Federal law classifies a kayak, canoe, rowboat, paddleboard, or engineless sailboat as a “vessel,” and non-motorized vessel regulations borrow heavily from the rules that apply to powerboats. You get real exemptions from registration, from some visual distress signals, and from a few equipment mandates. You do not get an exemption from carrying a life jacket for every person aboard, from the navigation rules, from the federal law against operating while impaired, or from accident reporting. Knowing where the exemptions stop is the part that keeps you legal.
Safety Equipment You Still Have to Carry
Life Jackets
Every person aboard a kayak, canoe, or other recreational vessel must have a Coast Guard-approved wearable personal flotation device that fits and is readily accessible.1eCFR. 33 CFR Part 175 – Equipment Requirements Children under thirteen must actually wear the PFD while the vessel is underway, unless they are below decks or in an enclosed cabin.2United States Coast Guard. Child Wear of Personal Flotation Devices An open canoe or kayak has no enclosed cabin, so for practical purposes every child wears one.
Canoes and kayaks sixteen feet or longer are exempt from the additional throwable device (like a ring buoy) that other boats need. Racing shells, rowing sculls, racing canoes, racing kayaks, and sailboards are exempt from PFD carriage requirements altogether, but only when actually used for racing.3eCFR. 33 CFR 175.17 – Exemptions Calling a touring canoe a “racing canoe” does not qualify.
A Light After Dark
A vessel under oars or paddles does not need mounted navigation lights. The operator must have a flashlight or lantern ready to show a white light in time to prevent collision.4eCFR. 33 CFR 83.25 – Sailing Vessels Underway and Vessels Under Oars A small sailboat under seven meters that cannot practicably display the full sailing-vessel lights falls under the same rule. If you paddle or sail between sunset and sunrise, or in fog or heavy rain, keep that light within arm’s reach instead of buried in a dry bag.
A Sound Signal
Any vessel under twelve meters, roughly 39 feet, does not need a formal horn but must carry “some other means of making an efficient sound signal.”5eCFR. 33 CFR 83.33 – Equipment for Sound Signals (Rule 33) A pealess whistle clipped to your PFD meets the requirement.
Distress Signals on Coastal Waters
On coastal waters, most boats sixteen feet or longer need day-and-night visual distress signals. Manually propelled boats and open sailboats under twenty-six feet without engines get a partial exemption: they need night signals only, and only when operating between sunset and sunrise.6eCFR. 33 CFR Part 175 Subpart C – Visual Distress Signals In daytime, these vessels are fully exempt. On inland lakes and rivers that are not designated coastal waters, the federal visual distress signal requirement does not apply, though some states layer on their own rules.
When Registration Is and Isn’t Required
Vessel registration is handled at the state level, and most states exempt kayaks, canoes, and other craft powered solely by paddles, oars, or poles. The exemption disappears the moment you attach any kind of motor, including a small electric trolling motor. The vessel is then reclassified as motorized and must be registered, with an application, a fee, and display of decals. Fees and renewal periods vary by state.
For vessels above a certain length, some states also require a formal title, with thresholds commonly falling between fourteen and sixteen feet. Even on a paddle-only canoe that your state will not register, the twelve-character Hull Identification Number stamped on the hull by the manufacturer remains the primary identifier for theft recovery, recalls, and any later sale or motor addition that pushes you into a registration regime.7eCFR. 33 CFR 181.25 – Hull Identification Number Format
Right of Way on the Water
The Inland Navigation Rules generally favor less maneuverable vessels. A power-driven vessel underway must keep out of the way of sailing vessels, and sailing vessels must keep out of the way of vessels that are fishing, restricted in their ability to maneuver, or not under command.8eCFR. 33 CFR Part 83 – Navigation Rules In open water, that usually means a powerboat yields to your sailboat or kayak. The limits catch paddlers off guard.
In a narrow channel or fairway, the hierarchy flips. A sailing vessel or any vessel under twenty meters must not impede the passage of a vessel that can safely navigate only within that channel.9eCFR. 33 CFR 83.09 – Narrow Channels (Rule 9) A container ship coming through a shipping lane does not yield to your kayak. Stay near the edges and cross quickly, perpendicularly.
When two sailing vessels meet with risk of collision, right of way turns on wind direction. If each has the wind on a different side, the one with wind on the port side yields. If both have the wind on the same side, the windward vessel yields to the leeward.10eCFR. 33 CFR 83.12 – Sailing Vessels (Rule 12) For two kayaks approaching each other, no federal rule assigns priority. The general duty of good seamanship applies: both operators take early, obvious action to avoid collision.
One zone to know: federal law puts a 500-yard protection perimeter around any U.S. naval vessel longer than 100 feet, and the rule applies to “every description of watercraft,” paddleboards and kayaks included.11eCFR. 33 CFR 165.2015 – Definitions Give any large gray hull a wide berth.
Paddling After Drinking
Federal law makes it a criminal offense to operate any vessel while intoxicated. Under 46 U.S.C. § 2302, an impaired operator faces a civil penalty of up to $5,000 or prosecution for a class A misdemeanor carrying up to one year in prison.12Office of the Law Revision Counsel. 46 USC 2302 – Penalties for Negligent Operations and Interfering With Safe Operation The statute says “vessel” without limiting it to motorized craft, so canoes, kayaks, rowboats, and paddleboards are covered.
Most states set the blood alcohol threshold for boating under the influence at 0.08%, matching motor vehicles.13Alcohol Policy Information System. Operators of Recreational Watercraft A handful of states use different numbers. Not every state applies its BUI law to non-motorized craft: some define “vessel” broadly enough to cover a canoe, others restrict the statute to motorized watercraft or exclude human-powered devices entirely. Check your state’s definition before assuming you cannot be charged.
Many states also have implied consent provisions that mirror driving law. By operating a vessel on state waters, you may be deemed to have consented to a breath or blood test when officers have probable cause for impairment. Refusing the test can trigger administrative suspension of boating privileges, separate from any criminal BUI charge.
When You Have to Report an Accident
A collision or capsizing in a canoe or kayak triggers the same federal reporting obligations as a powerboat crash. File a report with your state’s boating authority if any of the following happens:
- Death or disappearance: within 48 hours.
- Injury requiring treatment beyond first aid: within 48 hours.
- Property damage totaling $2,000 or more, or complete loss of any vessel: within 10 days.14eCFR. 33 CFR Part 173 Subpart C – Casualty and Accident Reporting
The $2,000 threshold is lower than most paddlers assume, and it covers damage to any property, not just your boat. Hitting a dock, scraping another vessel, or losing expensive gear in a swamping can cross the line fast. Reports go in on a Boating Accident Report form through the state agency that handles recreational boating.
Clean, Drain, Dry Between Waters
Kayaks and canoes are common vectors for aquatic invasive species, and enforcement is tightening. The U.S. Fish and Wildlife Service protocol applies to all watercraft:
- Clean: remove all visible plants, animals, and mud from the hull, deck, paddles, and gear before leaving the water access point.
- Drain: empty all water from the vessel, including water trapped in scupper holes, seat wells, or inflatable compartments.
- Dry: allow everything to dry for at least five days before entering a different body of water. If that wait is impractical, towel-dry thoroughly and rinse with hot tap water (120°F or higher when possible).15U.S. Fish and Wildlife Service. Clean, Drain, Dry
Many states require watercraft inspection stickers, decontamination at checkpoints, or both, with penalties that vary widely. At the federal level, the Lacey Act authorizes substantial fines for transporting injurious species. Organized events on infested waters increasingly require proof of decontamination. Wildlife agencies do not recommend bleach or chemical disinfectants on hulls because the chemicals can damage equipment and may not kill all invasive organisms.
If You Cross an International Border
Paddle across an international border, even briefly, and you must report your arrival to U.S. Customs and Border Protection immediately on returning to U.S. waters. The requirement applies to all vessels arriving from a foreign port or place, regardless of size or propulsion method.16U.S. Customs and Border Protection. Pleasure Boats A kayaker crossing from Canada on the Great Lakes or along the Pacific Northwest coast is subject to the same reporting duty as a yacht returning from the Bahamas.
Report through the CBP ROAM app or by calling a designated telephone reporting number. Float plans are no longer accepted as a reporting method. An in-person inspection at a port of entry may still be required, so plan your crossing to land at or near one.
