A boat used for fishing brings its own body of regulation, largely independent of fishing rules, and it is enforced on the water.
Registration and numbering
Most motorized vessels must be registered in the state of principal use, and the registration number must be displayed on the forward half of each side in a specified size, color contrast and style, with the validation decal placed as the state requires.
Requirements for non-motorized craft vary — some states register canoes and kayaks, many do not.
Registration reciprocity for visiting boats is common but time-limited, typically expressed as a number of consecutive days.
The equipment list
The federal baseline, with state additions, generally requires:
Life jackets — one wearable Coast Guard-approved PFD for every person aboard, plus a throwable device on any boat 16 feet or longer other than canoes and kayaks. Federal rules require children under 13 to wear one while a vessel is underway, and states layer their own age rules on top.
Fire extinguisher where the vessel has enclosed fuel or engine spaces, of the correct classification and within date.
Sound-producing device — a horn or whistle.
Visual distress signals for coastal and certain other waters, with the requirement varying by where you operate. Approved options include pyrotechnics, an orange distress flag and an electric distress light; flares carry expiry dates that are checked, and the signals must be readily accessible rather than stowed in a locker.
Navigation lights operating between sunset and sunrise and in restricted visibility.
Engine cut-off switch use is now federally required for certain vessels while on plane.
Where people fall short
Expired flares, a fire extinguisher that has lost charge, life jackets in the wrong size for the children aboard, and missing or unlit navigation lights.
None of these are difficult to satisfy, and all of them are visible in an inspection.
The other layer
Boater education certification is required in many states, often tied to birth-date cutoffs in the same way hunter education is.
And operating under the influence is enforced on water as it is on the road, frequently with the same thresholds and consequences.
What an inspection actually checks
Boarding officers work a list, and it is short: registration and numbering, one wearable PFD per person in serviceable condition, the throwable if the vessel requires one, a fire extinguisher of correct class and within date, a sound device, navigation lights, visual distress signals where required, and the engine cut-off link.
Serviceable condition is where most failures happen. A PFD with a torn strap, mildew or a seized buckle counts as unserviceable even though it is aboard, and the requirement is one that fits each person, which is why children aboard need their own sizes rather than adult spares.
The paperwork side
Registration numbers must be displayed on the forward half of each side in the specified size and contrast, with the decal placed where the state requires. Faded or peeling numbers are a citable defect on their own.
Reciprocity for visiting boats is time-limited and counted in consecutive days, so a long stay in another state can quietly move you out of compliance without anything changing on the boat.
