When Guests Chipping In Becomes an Illegal Charter: Passengers-for-Hire Rules for Boat Owners

Federal law (46 U.S.C. 2101) defines:

• Consideration: an economic benefit, inducement, right or profit, including money, going to a person or company. It does not include a voluntary sharing of the actual expenses of the voyage, whether by money or by donating fuel, food, drinks or other supplies.
• Passenger for hire: a passenger for whom consideration is contributed as a condition of carriage on the boat, whether it goes directly or indirectly to the owner, charterer, operator, agent or anyone else with an interest in the boat.

So the question isn't "did money change hands?" It's "was anything required in exchange for the ride?"

BoatUS explains it with a fishing example:

• "I'll take you fishing if you chip in for gas and bring lunch." The gas and lunch are a condition of the trip, so it's a charter, and the operator needs a Coast Guard credential.
• "I'll take you fishing." Friend: "Great, let me pay for gas and bring lunch." That's voluntary, so it's not a charter.

The Coast Guard's 2025 release says the same: voluntarily sharing actual expenses among friends is fine, but taking passengers in exchange for money or other consideration is not, without the proper license and vessel. Keep it truly voluntary, and only for real trip costs (fuel, food, ice, bait), not a "per person" price, boat payments or a profit.

"Consideration" is broader than cash for the ride. Red flags include: a set price per person or per hour, posting trips on social media or classified sites, payments that go to a friend or a company instead of to you, "donations" that are expected, trading a boat ride for services, or a business taking customers out as part of a deal. If there's any business angle, ask the Coast Guard before the trip.

A boat under 100 gross tons carrying not more than six passengers, at least one of them for hire, is an uninspected passenger vessel (46 U.S.C. 2101). It doesn't need a Coast Guard inspection certificate, but the Coast Guard says:

• The operator must hold a Coast Guard credential. The most common is the Operator of Uninspected Passenger Vessels (OUPV) endorsement, often called a "six-pack" license. The Coast Guard's release says all operators carrying passengers for hire must hold a Coast Guard license, and BoatUS notes you need one even for a single passenger for hire, with the credential aboard.
• Drug and alcohol testing: the operator and crew must be in a drug testing program, even for a one-person business (Coast Guard and BoatUS). BoatUS says proof can be a letter from a third-party administrator or a wallet card.
• Extra safety rules: uninspected passenger vessels have their own equipment rules in 46 CFR Subchapter C (our fire extinguisher guide notes some of the differences).

The licensed captain has to actually run the boat. The manning rule (46 CFR 15.605) says each self-propelled uninspected passenger vessel must be under the direction and control of a person holding a Merchant Mariner Credential endorsed as OUPV (or higher). Having a licensed friend "along for the ride" while you, unlicensed, drive the paying guests doesn't meet that test. Boats on international voyages have extra crew requirements.

The Coast Guard's 2025 release (May 24, 2025) lists a civil penalty of up to $49,848 for operating a vessel carrying six or fewer passengers without a Coast Guard license.

If a boat under 100 gross tons carries more than six passengers, including at least one for hire, it's a small passenger vessel and must be inspected by the Coast Guard and carry a Certificate of Inspection (COI) (46 U.S.C. 2101; the Coast Guard's 2025 release points to 46 CFR Subchapter T). The Coast Guard notes that a legitimate boat carrying more than six passengers for hire typically shows an inspection decal and posts its COI. An ordinary recreational boat can't simply "add more seats"; getting a boat inspected and certificated is a major project.

In a true bareboat (or demise) charter, the renter takes full possession and control of the boat and runs it, or hires a captain of their own choosing. Owners sometimes use a "bareboat" contract to dodge the rules while really providing the captain; the Coast Guard treats that as an illegal passenger operation. A Coast Guard investigator explained in a May 2026 release about a terminated Florida charter: "Once an owner dictates which captain the renter must use, it is no longer a bareboat charter." In that case, the boat carried 11 passengers and was cited for no Certificate of Inspection, no credentialed operator, no drug and alcohol program and no valid Certificate of Documentation.

Also, under 46 U.S.C. 2101, a boat chartered with no crew provided or specified by the owner becomes a small passenger vessel (needing inspection) if it carries more than 12 passengers.

Discover Boating describes peer-to-peer boat sharing as owners renting their boats to others when they're not using them, much like house or car sharing sites. Renting your boat through an app or website doesn't change the law. BoatUS reported in 2020 that many peer-to-peer platforms didn't verify captain credentials, and that a Coast Guard official in Chicago estimated that in summer 2017, 90% of boats offered on one platform didn't comply with federal rules. Before you list:

• Decide whether you're renting the boat bareboat (the renter operates or hires their own captain) or offering a captained trip (then the captain needs a credential and the rules in steps 4 and 5 apply).
• Read the platform's terms on who is responsible for licensing, safety equipment and compliance; usually it's you.
• Check state rental (livery) laws, which may require safety briefings, renter age checks or boater education for renters.

A typical personal (recreational) boat policy is written for pleasure use. Many exclude or suspend coverage when the boat is rented out, chartered or carrying paying passengers, which could leave you personally exposed after an accident. Before any paid use:

• Read the exclusions and "use" sections of your policy, or ask your agent for a written answer.
• If a rental platform offers insurance, find out exactly what it covers, when it applies, whether it's primary, and what your own policy does during the rental.
• Commercial use generally needs a commercial or charter policy.

Our insurance claim guide explains why a denied claim is so costly.

• Get the credential: for an OUPV endorsement, 46 CFR 11.467 requires at least 12 months of experience operating vessels (with at least 3 months on ocean or near-coastal waters for a near-coastal endorsement), plus the Coast Guard's exam, medical, drug test and other general requirements.
• Join a drug and alcohol testing program.
• Equip the boat to the uninspected passenger vessel rules, and consider the Coast Guard's voluntary UPV safety exam and decal, which the Coast Guard and BoatUS say passengers can look for.
• Documentation: if your boat is documented, make sure its Certificate of Documentation is valid and endorsed for the trade (see our documentation renewal guide); the Coast Guard cited a missing valid documentation certificate in the 2026 case above.
• Insurance and business: a commercial policy, and any state or local business or charter licenses.
• Ask the Coast Guard first: the Coast Guard's release invites owners who want to operate commercially to contact their local Coast Guard office for guidance.

The Coast Guard and BoatUS suggest asking the captain for:

• A Coast Guard-issued Merchant Mariner Credential (the captain's license), which must be aboard
• For more than six passengers, the Certificate of Inspection; for six or fewer, the voluntary UPV decal is a good sign
• Proof the operator is enrolled in a drug and alcohol testing program
• A safety briefing and enough life jackets for everyone (see our passenger briefing guide)

The Coast Guard notes that legitimate businesses advertise their compliance; if they don't, treat it as a warning sign.

The Coast Guard can stop and board a boat, terminate the voyage and escort everyone back to the dock. Its releases list civil penalties ranging up to tens of thousands of dollars per violation (for example, no credentialed operator, no Certificate of Inspection, no drug testing program, no valid documentation). The 2025 release adds that violating a Coast Guard order (such as an order to stop operating) can be a Class D felony with jail time and fines. Exact amounts are adjusted for inflation, so check the latest Coast Guard information.

If you suspect an illegal passenger operation, the Coast Guard asks you to contact your local Coast Guard Sector Investigations office or the Coast Guard Investigative Service (CGIS). In an emergency on the water, call VHF channel 16 or 911.
