1. Passenger Vessel Classifications

The number of passengers a vessel carries and its gross tonnage determine which Coast Guard regulatory subchapter applies. Getting the classification right is the foundation of every other passenger vessel rule.

The 6-Passenger Rule — OUPV License

An Operator of Uninspected Passenger Vessels (OUPV) license — commonly called a "6-pack" license — authorizes carrying up to 6 paying passengers on an uninspected vessel. The vessel does not need a Certificate of Inspection. The key word is "uninspected": the vessel is not exempt from safety equipment requirements, but it is not subject to Coast Guard inspection before each voyage.

OUPV Can Carry
  • Up to 6 paying passengers
  • Any number of non-paying guests
  • On uninspected vessels of any GRT
  • On inland, near-coastal, or limited-coastal routes (per license endorsement)
OUPV Cannot Do
  • Carry 7 or more paying passengers
  • Operate an inspected passenger vessel (COI vessel)
  • Operate beyond the geographic limit on the license
  • Act as Master of a vessel over 200 GRT
ClassificationRegulationPassengersTonnageLicense Required
OUPV (Uninspected — 6-pack)46 CFR Part 24 / 26Up to 6 payingAny GRTOUPV
Subchapter T (Inspected Small)46 CFR Subchapter T7–150Under 100 GTMaster (appropriate tonnage)
Subchapter K (Inspected Large)46 CFR Subchapter KOver 150Any (usually 100+ GT)Master 100 GT or higher
Subchapter H (Ocean Routes)46 CFR Subchapter HAny100 GT or moreMaster Ocean or Coastal

Subchapter T — Key Points

  • Capacity: 7 to 150 passengers
  • Tonnage: Under 100 gross tons
  • COI required: Yes — vessel must pass Coast Guard inspection
  • Stability: Must have stability booklet or letter on board
  • Lifesaving: Life rafts, immersion suits, EPIRBs as specified in COI
  • Examples: Head boats, dinner cruises, whale watches, dive boats

Subchapter K — Key Points

  • Capacity: Over 150 passengers
  • Fire protection: Structural fire protection; fire detection systems
  • Stability: More rigorous stability analysis; inclining experiment required
  • Crew: Larger minimum crew; fire brigade requirements
  • Drill frequency: Muster drills before every voyage with new passengers
  • Examples: Large ferries, casino boats, large excursion vessels

What Makes a Passenger a "Passenger for Hire"?

The definition of "passenger for hire" under 46 USC 2101 is critical. A person is a passenger for hire when "consideration is paid" — directly or indirectly — for carriage. This includes:

Counts as Consideration (Triggers License Requirement)
  • Cash payment for the trip
  • Fishing charter fee that includes transportation
  • Dive charter where fee includes boat ride
  • Admission ticket that includes boat excursion
  • Corporate event where employer pays for employee ride
  • Any in-kind trade where the operator receives value
Does NOT Count as Consideration
  • Splitting fuel costs only (pro-rata share)
  • Guest invited with no payment or benefit to operator
  • Crew member performing duties
  • Owner's family members riding along
  • Charitable event where operator donates the trip

2. Passenger Safety Briefing Requirements

46 CFR 26.03-3 requires that the operator of an uninspected passenger vessel give a safety briefing before or immediately after departure. Inspected vessels have additional requirements under their COI and Subchapter T or K.

46 CFR 26.03-3
Timing of Safety Briefing
The safety briefing must be given before departure or immediately after departure commences. "Immediately after" means as soon as it is practical to safely address passengers — before reaching open water or any potentially hazardous condition.
Briefing ItemRequired Detail
Life jacket locationsPoint to all PFD stowage locations; demonstrate donning if underway less than 3 miles from shore or in rough conditions
Fire extinguisher locationsIdentify all portable extinguisher locations and how to operate
Distress signal locationsShow where flares, horn, and EPIRB/PLB are stored
Muster stationTell passengers where to go and what to do if abandon-ship is ordered
Emergency exitsPoint out all means of exiting the cabin or enclosed space
Overboard emergency procedureExplain what to do if they see or hear a man overboard
No-go areas on deckIdentify restricted areas — anchor windlass, transom, engine hatches
Passenger countVerify number aboard matches manifest before departing

Muster Drill — Inspected Vessels

For Subchapter T and K vessels, a muster drill must be conducted before or at the beginning of each voyage. If passengers board at multiple stops, each new group must receive the safety briefing.

  • Demonstrate PFD donning — do not just point
  • Identify each crew member's emergency role
  • Explain the alarm signal and what it means
  • Show location of survival craft and launching procedure
  • Document drill completion in the log

Passenger Count Documentation

The number of persons aboard (POB) must be known at all times and must not exceed the COI limit. Best practice (and often required by regulation) includes:

  • Physical headcount before departure
  • Name or ticket log for each passenger
  • For offshore trips: float plan with passenger list
  • Leave a copy of manifest/float plan with shore contact
  • Update count if passengers disembark mid-trip

3. Passenger Manifest and Float Plan

While a float plan is not required by federal law for most small passenger vessels, it is mandatory in practice for responsible offshore operation and may be required by some state laws or COI conditions.

Passenger Manifest Requirements

Under 46 CFR 4.05-15, the owner/operator of a vessel involved in a marine casualty must provide a list of all persons aboard. Maintaining an accurate manifest at all times is therefore essential. The manifest should include:

  • Full legal name of each passenger
  • Emergency contact name and phone number
  • Medical conditions relevant to emergency response
  • Special needs or mobility limitations
  • Embarkation and planned disembarkation point
  • Total count of souls aboard (passengers + crew)

Float Plan Best Practice

A float plan is left with a responsible person ashore before departure. The Coast Guard recommends but does not mandate it for most small vessel operations. It should contain:

  • Vessel name, documentation or registration number
  • Description: length, hull color, engine type
  • EPIRB registration number and hex ID
  • Departure point, destination, intended route
  • Estimated time of departure and return
  • VHF channels monitored
  • Names and contact info of all persons aboard
  • Instructions: "If we have not contacted you by [time], call USCG at [number]"

When a Manifest IS Legally Required

Certain vessels and routes trigger a mandatory passenger manifest under federal regulation: passenger vessels on international voyages must maintain a manifest under 19 CFR 4.7; Subchapter K vessels must maintain records of persons aboard per 46 CFR Subchapter K; vessels subject to SOLAS must comply with passenger list and muster requirements. Additionally, some states require charter boat operators to file trip reports that function as manifests for search-and-rescue purposes.

4. Passenger Embarkation and Disembarkation

More passenger injuries occur at the dock than at sea. Safe boarding and departure procedures are a core exam topic and a critical real-world skill.

StepProcedure
Pre-boarding countCount and record all passengers before anyone boards
Gangway conditionInspect gangway, boarding ladder, or dock for slippery surfaces and stability
Fender placementConfirm vessel is fendered and lines are taut but not binding
One at a timeBoard passengers one at a time in rough conditions or when vessel is moving
Assist elderly/disabledStation a crew member at boarding point for every departure
Weight distributionDirect passengers to correct positions to maintain trim and stability
Gear stowageAll heavy gear below or centered on centerline before departure
Manifest updateRecord any late arrivals or no-shows; update before departure

Gangway Safety Requirements

  • Handrails: Required on both sides of any gangway or boarding ramp
  • Non-slip surface: Gangway treads must provide traction in wet conditions
  • Load rating: Gangway must be rated for the maximum load it will carry
  • Crew supervision: A crew member must be stationed at gangway during boarding
  • Cleats and lines: Vessel secured with sufficient lines so gangway angle does not change during boarding
  • Lighting: Adequate lighting required for night boarding

Boarding in Rough Conditions

  • Captain's discretion: The captain may refuse boarding if conditions make it unsafe
  • One at a time: When there is surge, board passengers individually with crew assistance
  • Timing the surge: Assist passengers across at the moment of least relative motion
  • PFDs at pier: Consider donning PFDs before boarding in extreme conditions
  • Capacity check: Verify capacity limits before the last passenger boards, not after
  • Trim check: Check vessel trim and heel before releasing dock lines

5. Passenger Crowding and Stability

Passenger crowd shifting is one of the most dangerous stability events on small vessels. The exam tests your knowledge of how passenger weight affects stability and what limits apply.

The 140-Pound Passenger Weight Standard

The Coast Guard uses 140 pounds as the standard assumed weight per passenger for small passenger vessel stability calculations. This is the figure used to determine:

GZ Calculation
Righting arm when all passengers move to one side
Freeboard Check
Whether deck edge submerges with full passenger load
Downflooding Angle
Whether the vessel can heel to the downflooding point
Exam note: When asked about worst-case crowding, assume ALL passengers move to one side simultaneously. The stability letter or COI specifies whether the vessel passes this test. If it fails the worst-case heel calculation, the COI passenger capacity is reduced until the vessel passes.

Effects of Passenger Crowding on Stability

  • Increased displacement: More weight pushes vessel deeper, reduces freeboard
  • Raised center of gravity: Passengers standing on deck raise G, reducing GM
  • Free surface effect: Any liquids aboard also reduce stability
  • Asymmetric loading: Crowd on one side creates static heel
  • Dynamic effects: Crowd rushing to one side in response to a wave can cause rapid roll
  • Reduced reserve buoyancy: Lower freeboard means less ability to recover from a wave

Operator Actions to Manage Crowding

  • Pre-departure: Distribute passengers evenly; brief them not to crowd one rail
  • Fish on side: When passengers crowd to fish, maintain vessel trim with throttle and helm
  • Whale watch: Instruct passengers to spread out; use PA system to direct movement
  • Heavy weather: Seat passengers low and centered; prohibit movement on deck
  • Anchor deployment: Move passengers aft before anchoring; brief before MOB recovery
  • Authority to order: Captain has authority to direct passenger movement for safety

6. Americans with Disabilities Act — Passenger Vessels

The ADA applies to passenger vessels operated by private entities as a "public accommodation." The Department of Transportation issued final ADA Accessibility Guidelines for Passenger Vessels (ADAAG-PV).

CategoryRequirement
Boarding accessVessels must provide at least one accessible boarding point where feasible. Fixed gangways must accommodate wheelchairs where practicable.
SeatingAt least a portion of passenger seating must be accessible. Knee clearance and aisle width must accommodate mobility devices.
RestroomsIf restrooms are provided, at least one must be accessible to persons with disabilities, including turning radius and grab bars.
Emergency evacuationOperators must have an emergency evacuation plan that includes passengers with mobility impairments. Pre-boarding assistance planning is required.
Service animalsService animals must be permitted aboard all passenger vessels. The animal must be under control and the passenger is responsible for the animal.
CommunicationSafety briefings must be accessible. Written or visual alternatives must be available for hearing-impaired passengers.
New vessel constructionVessels built after 2010 must comply with ADA Accessibility Guidelines for Passenger Vessels (ADAAG-PV) from keel up.

ADA Exam Key Points

What operators MUST do
  • Permit service animals (not just guide dogs)
  • Provide accessible boarding where feasible
  • Make reasonable modifications to policies and procedures
  • Provide effective communication alternatives
  • Have an emergency evacuation plan for disabled passengers
What operators are NOT required to do
  • Modify a vessel if it would fundamentally alter the nature of the service
  • Make modifications that create undue financial or administrative burden
  • Make structural changes that compromise vessel safety or seaworthiness
  • Carry passengers who pose a direct threat to the safety of others
  • Carry passengers whose condition the crew cannot safely manage

7. Charter Party Agreements

The charter party agreement defines the legal relationship between vessel owner and charterer. The type of charter determines who holds the operator license requirement, who carries liability, and how the vessel's COI applies.

Crewed Charter (Passenger-for-Hire)

Owner provides vessel AND crew. Passengers pay for transportation or recreation.

License:
OUPV or Master required
Inspection:
COI required if 7+ passengers
Insurance:
Commercial marine liability required
Liability:
Owner/captain liable for passenger safety

Bareboat Charter (Demise Charter)

Owner transfers full possession and control to charterer. Charterer acts as owner pro tempore.

License:
Charterer must have required license if carrying others for hire
Inspection:
COI travels with vessel, not the charter arrangement
Insurance:
Charterer typically provides own insurance or indemnifies owner
Liability:
Charterer assumes owner-level responsibility during charter period

What a Charter Party Agreement Should Include

Operational Terms
  • Dates and times of charter
  • Departure port and route
  • Vessel identification
  • Number of passengers allowed
  • Services to be provided
  • Weather cancellation policy
Financial Terms
  • Charter fee and payment schedule
  • Deposit and refund policy
  • Fuel surcharge provisions
  • Gratuity policy
  • Late departure penalties
  • Force majeure clause
Legal Provisions
  • Liability disclaimer / limitation
  • Indemnification clause
  • Governing law / jurisdiction
  • Alcohol and conduct rules
  • Captain's authority statement
  • Insurance requirements

8. Operating Limits in the Certificate of Inspection

The Certificate of Inspection (COI) is issued by the USCG and is the definitive authority on what an inspected vessel may do. Operating outside COI limits is a federal violation and may void insurance.

COI RestrictionWhat It Means
Passenger limitMaximum number of passengers stated on COI; may NOT be exceeded under any circumstances
RouteGeographic waters authorized: inland, near coastal, coastal, ocean, limited coastwise, etc.
Distance from shoreMay be limited to within 3 miles, 20 miles, 200 miles, or other specific distance
Sea state / weatherSome COIs restrict operation in wind above a Beaufort rating or wave height
Hours of operationDaylight-only restrictions are common on smaller or older vessels
Crew requirementsMinimum required crew listed; cannot depart short-handed
Equipment carriageSpecific lifesaving and fire equipment must be aboard and maintained
Stability letterVessel must operate within the weight and distribution limits of its stability letter

Route Classifications on the COI

  • Inland waters: Rivers, lakes, harbors — protected from ocean swells
  • Near coastal (NC): Within 200 miles of a harbor of safe refuge
  • Limited coastwise: Within a specific, restricted geographic area
  • Coastwise: Along the coast, within baseline limits
  • Ocean: Unrestricted blue-water operations
  • Lakes, bays, sounds: Specific protected waters only

What Happens if You Exceed COI Limits

  • Civil penalty: Up to $10,000 per violation per day
  • Criminal penalty: Willful violations can result in prosecution
  • License action: USCG may suspend or revoke the operator's license
  • Insurance void: Insurers routinely deny claims if vessel operated outside COI
  • Liability exposure: Personal liability for any injury or damage is unlimited
  • Vessel detention: USCG may detain the vessel until deficiencies are corrected

9. Passenger Conduct and Captain's Authority

The master of a vessel has broad authority over everyone aboard. This authority is not merely contractual — it is grounded in federal maritime law and is essential for safety of life at sea.

The Master's Authority Under Federal Law

Under 46 USC 11101-11104, the master has command over all persons aboard. This is not merely a nautical tradition — it is a statutory duty. The master is responsible for the safe navigation of the vessel, the safety of all persons aboard, and compliance with all applicable laws and regulations. This authority includes:

Authority TO:
  • Refuse passage to any person who poses a safety threat
  • Order passengers to a specific location on the vessel
  • Prohibit a passenger from consuming alcohol
  • Confine a disruptive passenger to a designated space
  • Return to port early due to passenger conduct or weather
  • Conduct a search if there is reasonable cause to believe weapons or drugs are aboard
  • Order abandon ship without further authorization
Authority LIMITATIONS:
  • Cannot refuse passage based on protected class (race, sex, disability, etc.)
  • Cannot use excessive force — reasonable force only
  • Cannot detain a passenger indefinitely in port — must summon law enforcement
  • Cannot authorize illegal searches without probable cause or consent
  • Cannot deny a passenger medical assistance
  • Cannot retaliate against a passenger for filing a complaint

Grounds to Refuse Passage

  • Visible intoxication: Passenger appears impaired — a direct safety risk
  • Over capacity: Vessel has reached COI passenger limit
  • Threatening behavior: Passenger has made threats or acted aggressively
  • Medical contraindication: Passenger's condition creates a safety risk the captain cannot manage
  • Prohibited items: Passenger refuses to surrender a weapon or contraband
  • Unaccompanied minor: Minor below minimum age without required adult guardian

Managing Disruptive Passengers Underway

  • Document everything: Log all incidents with time, location, witnesses
  • Verbal first: Give clear, direct orders before any physical intervention
  • Separate: Move disruptive passenger away from other passengers
  • Return to port: If passenger poses ongoing risk, return to port and summon law enforcement
  • Crew backup: Never handle a disruptive passenger alone — use crew as witnesses
  • Radio ahead: Request law enforcement meet the vessel at the dock

10. Revenue Documentation — License and Charter Requirements

Operating commercially requires specific documentation. The license type, the number of passengers, and the nature of the consideration paid all determine what paperwork is required.

6-Pack (OUPV) Documentation

  • OUPV license: Must be aboard the vessel and available for inspection
  • Vessel documentation or registration: Coast Guard documentation or state registration must be current
  • Equipment: PFDs for all aboard, fire extinguisher, flares, horn — as required by vessel class
  • No COI required: Uninspected vessel is not subject to COI requirement for 6 or fewer paying passengers
  • Commercial endorsement: Ensure OUPV license has correct ocean or inland endorsement for the route
  • Insurance: Not federally required but commercially essential; most marinas and charters require it

Charter Party Documentation

  • Charter party agreement: Written contract is best practice and may be required by insurance
  • Master license: If 7+ passengers, Master (appropriate tonnage) required
  • COI: Must be posted aboard in a conspicuous location
  • Stability letter: Must be aboard; compliance required at all times
  • Safety management system: Required for some Subchapter K and H vessels
  • Drug testing records: Commercial mariners in safety-sensitive positions subject to DOT drug testing; records maintained by employer

Commercial Fishing vs. Passenger Carrying

A commercial fishing license does NOT authorize carrying passengers for hire. These are entirely separate regulatory regimes. A vessel may hold both a commercial fishing permit and a passenger-for-hire authorization, but they cannot be used simultaneously for mixed fishing-and-passenger trips unless the vessel has the appropriate COI or OUPV license AND the commercial fishing permit explicitly allows it.

Commercial Fishing License
  • Authorizes: harvesting fish commercially
  • Does NOT authorize: carrying paying passengers
  • Issued by: NOAA / state fishery agency
  • Vessel type: commercial fishing vessel (CFV)
Passenger for Hire (Head Boat)
  • Authorizes: carrying paying passengers for fishing trips
  • Requires: OUPV or Master license + COI if 7+
  • Issued by: USCG
  • Fish caught: belong to passengers (recreational catch)

11. Alcohol and Intoxication Rules

Federal BUI law is stricter for commercial operators than for recreational boaters. The exam tests both the specific BAC thresholds and the jurisdictional reach of federal law.

RuleThreshold / StandardAuthority
Federal BAC limit — Commercial operator0.04%46 USC 2302; 33 CFR 95
Federal BAC limit — Recreational operator0.08%46 USC 2302
JurisdictionAll navigable U.S. watersFederal law preempts state
Enforcement authorityUSCG, state officers, local law enforcement46 USC 2302(c)
Sobriety testingUSCG may conduct field sobriety and breathalyzer tests33 CFR 95.055
Refusal to testCreates rebuttable presumption of intoxication33 CFR 95.060
Conviction penaltyUp to $5,000 civil / $10,000 criminal fine; up to 1 year imprisonment; license suspension46 USC 2302(d)
Passenger alcoholNot federally prohibited; state law varies; captain may prohibit aboard vesselCaptain's authority / state law

Federal vs. State Jurisdiction on BUI

Federal BUI law (46 USC 2302) applies on all navigable waters of the United States, including waters within state territorial jurisdiction. The Coast Guard can enforce federal BUI even on waters that are entirely within a single state.

State BUI laws may be more restrictive than federal law. When state law is more restrictive (lower BAC threshold, additional penalties), both federal and state law apply — the operator is subject to whichever is more stringent.

A conviction under federal BUI law is reported to the Coast Guard, which may then take license action under the mariner credentialing regulations at 46 CFR Part 5.

Passenger Alcohol — What the Law Says

Federal law does not prohibit passengers from consuming alcohol aboard a vessel. However:

  • Captain's authority: The captain may prohibit alcohol consumption for safety reasons and may refuse further service to any passenger who appears intoxicated
  • State law varies: Some states prohibit open containers of alcohol on vessels; check applicable state law
  • Dram shop liability: Operators who serve alcohol may face civil liability if a passenger is injured after being served by the operator
  • Minors: Serving alcohol to minors is illegal under all state laws and may trigger federal liability
  • Disembarkation: An intoxicated passenger who must drive from the marina creates a separate liability concern

12. Passenger Emergency Procedures

Emergencies with passengers aboard require the captain to simultaneously manage the technical emergency AND control crowd behavior. Both failure modes — mishandling the emergency itself or failing to manage passenger panic — can be fatal.

Man Overboard with Passengers Aboard

  1. 1Shout MOB and throw a life ring immediately — assign crew member to point at victim continuously
  2. 2Execute immediate turn — Williamson turn, Anderson turn, or racetrack depending on conditions
  3. 3Assign one crew member to manage passenger crowd control and keep passengers away from rescue side
  4. 4Direct passengers to move to the opposite side from recovery to reduce heel and improve freeboard
  5. 5Radio MAYDAY or PAN-PAN with position and description of victim
  6. 6Assign crew to recovery operation; keep passengers seated and away from working deck
  7. 7Log time, position, description, and all actions taken

Fire Aboard with Passengers

  1. 1Sound alarm — FIRE, FIRE, FIRE — and assign crew to attack fire with extinguisher
  2. 2Move passengers away from fire, upwind, and toward designated muster station
  3. 3Broadcast MAYDAY on VHF Ch 16 with vessel name, position, souls aboard, and nature of emergency
  4. 4Assign crew to don passengers into life jackets if abandon-ship appears likely
  5. 5Shut down fuel supply to engine if fire is in engine room
  6. 6Evaluate whether to fight fire or abandon ship — do not risk passengers on an unwinnable fight
  7. 7If ordered to abandon ship, initiate controlled disembarkation with disabled and children first

Abandon Ship with Passengers

  1. 1Give the order clearly: ABANDON SHIP — everyone into life jackets NOW
  2. 2Deploy life raft or survival craft and inflate/launch per equipment instructions
  3. 3Disembark in order: children first, then elderly and disabled, then remaining passengers, crew last
  4. 4Activate EPIRB and handheld VHF before leaving vessel
  5. 5Assign crew members to assist each group into the raft
  6. 6Account for every person using the pre-departure manifest
  7. 7Keep group together — tie life raft to another floatation device if available
  8. 8Signal rescuers with flares, mirror, whistle, and EPIRB signal

Critical Emergency Principles with Passengers Aboard

Control the Crowd First

Passenger panic kills. Before managing the technical emergency, get clear orders to passengers — loud, calm, authoritative commands. A panicked crowd rushing to one side can capsize a vessel.

Communicate Early

Radio MAYDAY as early as possible. Do not wait until the situation is catastrophic. Early communication brings faster rescue response and creates a legal record of your actions.

Crew Assignments

Every crew member must have a pre-assigned emergency role. Brief crew before each trip. In an emergency, there is no time to assign roles — everyone must already know their job.

13. Practice Problems with Solutions

These questions are representative of the format and difficulty level on the USCG OUPV and Master exams. Attempt each one before reading the solution.

Q1. You hold an OUPV license. A dive shop wants to pay you to take 8 divers to a reef 5 miles offshore. Can you do this trip under your current license?

Answer: No. An OUPV license authorizes carrying a maximum of 6 paying passengers. Eight paying passengers require at least a Master's license AND a vessel with a Certificate of Inspection from the Coast Guard. To do this trip legally, you would need: (1) a Master's license in the appropriate tonnage for the vessel, (2) the vessel to have passed a USCG inspection and hold a valid COI authorizing 8+ passengers, and (3) the COI to authorize the route (5 miles offshore within the near-coastal limit).

Q2. A passenger vessel stability calculation assumes a worst-case scenario where all passengers crowd to one side. A 35-foot head boat has a COI limit of 22 passengers. What total weight is used for the worst-case heel calculation?

Answer: 22 × 140 lbs = 3,080 lbs. The Coast Guard uses 140 pounds as the standard assumed weight per passenger. With 22 passengers at the COI maximum, the worst-case side load is 3,080 pounds concentrated on one side of the vessel. The stability analysis must demonstrate that the vessel will not reach the angle of downflooding with this loading. If the vessel cannot pass this test, the COI passenger limit is reduced until it does.

Q3. A passenger arrives at the dock clearly intoxicated and demands to board for a 3-hour sunset cruise. He is a paying customer with a ticket. What should the captain do?

Answer: Refuse boarding. The captain has both the authority and the duty to refuse boarding to any passenger who poses a safety risk. Visible intoxication is an explicit ground for refusal. The fact that the passenger holds a ticket and has paid does not override the captain's authority. The captain should: (1) calmly inform the passenger they cannot board for safety reasons, (2) offer a refund per the charter party agreement's terms, (3) document the refusal in the log with time and reason, and (4) if the passenger becomes threatening, contact marina security or local law enforcement. This is not discriminatory because intoxication is a conduct-based safety concern, not a protected class.

Q4. You are operating a Subchapter T vessel with 45 passengers when you hear an explosion in the engine room and smell smoke. What is your immediate priority sequence?

Answer: Sound the alarm, control the crowd, fight fire, communicate, decide.

  1. Sound the fire alarm — alert all crew immediately
  2. Order passengers to the muster station — keep them away from the engine room and upwind
  3. Assign a crew member to assess the fire and attempt suppression with the fixed system and extinguishers
  4. Assign a second crew member to begin donning passengers in life jackets
  5. Broadcast MAYDAY on VHF Ch 16 with vessel name, position, nature of emergency, souls aboard
  6. Shut off fuel supply to the engine room
  7. Evaluate: fight or abandon ship — do not risk 45 lives on an unwinnable fire

The key exam point: passenger crowd control happens simultaneously with the emergency response, not after. Failing to move passengers could result in panic, stampede, or destabilization of the vessel.

Q5. A charter customer wants a bareboat charter of your 38-foot vessel for a week. He says he has 20 years of boating experience but no license. He plans to take 10 friends. Is this legal?

Answer: Not legal as described. A bareboat charter transfers control of the vessel to the charterer. However, if the charterer is taking 10 "friends" who are paying for the trip, those friends are "passengers for hire" and the charterer is now an operator of a passenger-for-hire vessel requiring a license and COI. Without a license and COI, the trip is illegal for 10+ paying passengers. Even as a bareboat charter, if consideration is being paid for transportation, the passenger-for-hire regulations apply. A true bareboat charter works legally only if the charterer operates the vessel for their own pleasure and guests are genuinely not paying for transportation.

Q6. Your COI specifies the vessel is limited to "inland waters only." A customer wants to cross a bay from one dock to another — a 2-mile trip that is technically within state waters but outside the inland demarcation line. Can you make this trip?

Answer: No — not without a COI amendment or deviation request. The COI's route restriction controls, not the vessel's physical location. "Inland waters" on a COI refers to waters inside the demarcation lines established by the USCG. If the crossing requires going outside the inland demarcation line — even briefly — the vessel is operating in near-coastal waters, which the COI does not authorize. Operating outside the COI is a federal violation regardless of the distance or the apparent simplicity of the trip. To make this trip legally, the operator would need the USCG to amend the COI to add a near-coastal or limited coastwise route endorsement.

Q7. During a whale watch with 55 passengers, a humpback whale surfaces 50 yards away on the port side. All 55 passengers rush to the port rail to look. What should the captain do immediately?

Answer: Immediate PA announcement to redistribute passengers; use helm and throttle.

Steps in order:

  1. Get on the PA immediately — calm but authoritative tone: "Everyone, please spread across the deck for the best view. We need even weight distribution to give you the smoothest ride." Frame it as a benefit to them, not a safety order (passengers respond better)
  2. Use slow speed maneuvering to turn the vessel so the whale is directly ahead — removes the one-sided crowding problem entirely
  3. If vessel has already heeled significantly, apply opposite helm and differential throttle to help bring vessel back upright
  4. Monitor freeboard — if the deck edge is at or near the waterline, stop the vessel and broadcast a more direct order
  5. Brief crew to assist in redistributing passengers physically if the PA announcement is insufficient

The exam point: 55 passengers × 140 lbs = 7,700 lbs suddenly on one side of a small vessel is a genuine capsize risk. This happened in a real incident (the Leah Marie on Lake Erie in 2003) — passenger rush to one side caused capsizing and deaths.

Q8. A USCG boarding team tests you and your mate with a breathalyzer. You blow 0.03% and your mate blows 0.05%. Who is in violation of federal law?

Answer: Both are below the 0.04% federal commercial limit — but the mate at 0.05% is technically over 0.04% and IS in violation. You at 0.03% are NOT in violation of the BAC limit.

Detail: The federal commercial operator limit under 33 CFR 95 is 0.04% BAC. Your mate at 0.05% exceeds this limit and is in violation. You at 0.03% are below the limit. However, 0.03% BAC does not mean you are unimpaired — the Coast Guard can still take action under the "impairment" standard even below the per se BAC limit if observed behavior indicates impairment. Additionally, the vessel owner/operator can be held responsible if they knowingly permitted an impaired crew member to operate.

Q9. A passenger with a mobility impairment requests boarding assistance but your vessel has no accessible gangway. The ADA requires you to provide access — but you are on a 30-year-old wooden boat with a steep boarding ladder. What is your legal obligation?

Answer: You must make reasonable modifications, but structural changes that are not "readily achievable" or that would compromise vessel safety are not required.

The ADA requires "readily achievable" barrier removal and "reasonable modifications" to policies and procedures. For this vessel:

  • You ARE required to: provide crew assistance with boarding, use alternative boarding methods (portable ramp, step stool) if feasible, offer the lowest available boarding point
  • You are NOT required to: structurally modify the vessel if it would compromise seaworthiness, install permanent accessible gangway if it creates an undue burden or safety risk
  • You CANNOT: simply refuse to serve the passenger because it is "too hard"
  • Best practice: Have a written accessibility policy; contact the passenger before the trip to plan safe boarding; document all assistance provided
Q10. A passenger falls overboard from your 6-pack charter boat 8 miles offshore. You have 5 other passengers. What do you do?

Answer: Immediate MOB response — shout, throw, turn, assign, radio, recover.

  1. Shout "MAN OVERBOARD" — loudly so everyone aboard hears it
  2. Throw a life ring toward the victim immediately; if you have a horseshoe buoy with a light and whistle, throw that too
  3. Assign one of the remaining 5 passengers or crew (if any) to point at the victim continuously — never let the pointing stop
  4. Note time and GPS position of MOB
  5. Begin Williamson turn or Anderson turn to return to victim
  6. Radio PAN-PAN on VHF Ch 16: "PAN-PAN, PAN-PAN, PAN-PAN, this is [vessel name], we have a man overboard at position [latitude/longitude], vessel is [description], [number] souls remaining aboard, we are maneuvering for recovery"
  7. Direct remaining passengers to move to opposite side from recovery to give freeboard on recovery side
  8. Approach victim from downwind; stop engines before victim is near propellers
  9. Recover victim using swim ladder, life sling, or crew assist
  10. Provide first aid; if hypothermia suspected, keep victim warm; report to USCG when complete
Q11. What is the minimum required content of a passenger safety briefing on an uninspected vessel operating under an OUPV license?

Answer: Under 46 CFR 26.03-3, the safety briefing for an uninspected passenger vessel must cover at minimum:

  • Location of all life preservers (PFDs) and how to use them
  • Location of all fire extinguishers and how to use them
  • Location of all visual distress signals (flares)
  • Emergency procedures to be followed
  • Location of the first aid kit

The briefing must be given before or immediately after departure. There is no requirement to do it before leaving the dock — "immediately after departure" allows a brief delay if departure conditions require the captain's full attention. However, the briefing must be completed before reaching open water or any potentially hazardous condition.

Q12. You are completing a charter trip when your last remaining passenger tells you she left her bag aboard, and demands you take the boat back out. You are already docked. Are you obligated to do this?

Answer: No legal obligation to take the vessel back out; but you do have duties regarding the property.

The charter trip is complete. You are not required to operate the vessel for any additional purpose. However:

  • You likely have a duty to safeguard personal property left aboard — take possession of the bag and make it available for the passenger to retrieve from the dock
  • If the charter party agreement addresses lost/left property, follow those terms
  • If the bag was left at a mooring or anchor location offshore, you would need to retrieve it on your own terms — the passenger has no right to commandeer the vessel
  • Document the property and return it through the marina or arrange a reasonable pick-up
Q13. A service dog belonging to a visually impaired passenger vomited on the main deck. Another passenger is severely allergic to dogs and demands the service dog be removed or confined. What does the ADA require?

Answer: The service dog stays. The captain must accommodate both passengers through management, not removal of the service animal.

Key ADA principles in conflict:

  • Service animals must be permitted on all passenger vessels — removing the dog is an ADA violation
  • The handler is responsible for the animal's behavior; the vomiting should be cleaned up promptly
  • The allergic passenger's needs must also be accommodated through reasonable means: moving the allergic passenger to the greatest distance from the dog on the vessel, ensuring the area is cleaned, providing fresh air positioning
  • Neither passenger takes priority over the other — the captain must find a solution that allows both to remain aboard
  • If the service animal poses a genuine direct threat (aggressive behavior, uncontrollable), the handler can be asked to remove the animal — but allergies and cleanliness concerns do not meet the "direct threat" standard
