New Kentucky Boating Laws: Safety Gear, BUI, and Fines

Kentucky boating laws require most motorized vessels to be registered with the Department of Fish and Wildlife Resources, require anyone born on or after January 1, 1975 to carry a safe boating certificate, set specific safety-equipment rules, and treat operating under the influence as a criminal offense with escalating penalties. A 2021 update widened who needs the certificate, so even boaters who have been on Kentucky water for decades may now be out of compliance without realizing it.

Who Needs a Safe Boating Certificate

Kentucky does not issue a boating license the way it issues a driver’s license, but it does require boater education for a large share of operators. Under a 2021 change, anyone born on or after January 1, 1975 must carry a Kentucky Safe Boating Certificate Card, or equivalent documentation, when operating a personal watercraft or a motorboat of any horsepower on public waters.¹ Before that law, the certificate was only required for operators aged 12 to 17 on vessels with 10 or more horsepower.

The course is approved by the Kentucky Department of Fish and Wildlife Resources and covers navigation rules, emergency procedures, and state-specific regulations. You can take it online or in person, and it ends with a proctored exam. Once you pass, the certificate does not expire.² Visitors can use a certificate from their home state if it came from a NASBLA-approved course.

No one under 12 may operate a motorboat or personal watercraft with 10 or more horsepower on Kentucky public waters, certificate or not.²

Registering Your Boat

Every mechanically powered vessel used primarily in Kentucky has to be registered through your county clerk’s office with proof of ownership.² Base registration fees run by length:

Class A, under 16 feet: $22.20
Class 1, 16 to under 26 feet: $42.28
Class 2, 26 to under 40 feet: $52.85
Class 3, over 40 feet: $68.71

Those figures cover the registration only. County clerk fees, titling, and property tax apply on top.²

You’ll receive a certificate of registration and a validation decal, and both must be on the vessel. The registration number goes on both sides of the bow in plain block letters at least three inches high, in a color that contrasts with the hull.² Faded or missing numbers are enough to draw a citation.

If you sell a boat, notify the county clerk of the transfer within 15 days. The buyer takes the endorsed title to the clerk to close out the transaction.² Boats registered in another state can operate on Kentucky waters for up to 60 consecutive days before Kentucky registration is required.

Required Safety Equipment

Every vessel must carry a U.S. Coast Guard-approved life jacket for each person on board, sized appropriately and readily accessible. Children under 12 must actually wear one at all times on the open portion of any vessel that is underway.³ Violating the child life jacket rule is a $50 fine.⁴

Motorboats with enclosed engine compartments, closed fuel storage, or living quarters must carry fire extinguishers. Vessels from model year 2018 and newer must carry 5-B or 20-B rated extinguishers with a date stamp; a single 20-B counts for two 5-B units. Boats built between 1953 and 2017 can use either the newer 5-B/20-B extinguishers or the older B-I/B-II rated ones, as long as they are in good and serviceable condition.⁵

Boats operating between sunset and sunrise must display navigation lights appropriate to their type, and boats with permanently installed fuel tanks need ventilation systems to prevent gas fume buildup.

Personal Watercraft Rules

Personal watercraft follow the same general rules as other motorboats plus a few restrictions that catch people out. PWC operation is limited to the hours between sunrise and sunset. There is no running-lights workaround.²

Every person on a PWC must wear a Coast Guard-approved life jacket at all times, not just have one aboard. If the craft lacks self-circling capability, a lanyard-style engine kill switch has to be attached to the operator whenever the craft is underway.² Federal law separately requires anyone operating a recreational vessel under 26 feet, which covers nearly all PWC, to use an engine cut-off switch link while on plane or above displacement speed, if the vessel is equipped with one.⁶

Personal watercraft are prohibited on Cedar Creek Lake.²

Operating Rules on the Water

Idle speed under Kentucky law is the slowest speed at which a boat can maintain maneuverability, which typically means putting it in gear without advancing the throttle. Any posted “No Wake” buoy or sign requires that speed.² These zones cluster around marinas, docks, ramps, and congested traffic areas.

Operators are liable for any injury or damage caused by their boat’s wake, even outside a posted no-wake zone.² If your wake swamps a kayak or damages a moored boat, the signage does not shield you.

Water skiing is prohibited within 100 feet of any commercial boat dock, swimming area, or moorage harbor, and within 2,000 feet of a lock or dam.² Individual lakes may add horsepower or speed restrictions, so read the posted signs before opening up.

Boating Under the Influence

Operating any motorboat, vessel, or water ski while intoxicated or under the influence of drugs is illegal under KRS 235.240.⁷ The threshold is a blood alcohol concentration of 0.08%, the same as for driving.⁸ Kentucky does not apply a lower BAC to boaters under 21, unlike its driving laws.

By operating a vessel on Kentucky waters you give implied consent to a breath or chemical test if an officer has probable cause to suspect impairment.⁷ Refusing the test is itself an offense.⁴

Penalties climb with each conviction:

First offense: $200 to $250 fine or 24 hours of imprisonment
Second offense: $350 to $500 fine or 48 hours of imprisonment
Third or subsequent offense: $600 to $1,000 fine or at least 30 days in county jail, or both

These penalties sit outside Kentucky’s driving DUI statutes. A boating-under-the-influence conviction does not trigger driver’s license suspension or the penalties under KRS Chapter 189A.⁴ Intoxicated boating that causes serious injury or death can still bring separate felony charges under other criminal statutes.

Reporting a Boating Accident

If a boating incident results in death or a person disappearing from a vessel, the operator must notify the Kentucky Department of Fish and Wildlife Resources or the nearest conservation officer immediately, by the quickest available means. A written report follows within 48 hours.⁹

The same 48-hour written-report deadline applies when someone is injured badly enough that they can’t perform their usual activities. For property damage over $500 or a total vessel loss, you have 10 days.⁹ Reports must include location, time, nature of the accident, and identifying information for all people and vessels involved. Failing to report a qualifying accident violates KRS 235.250 and can bring misdemeanor charges and civil penalties.

Fines for Common Violations

Conservation officers with the Department of Fish and Wildlife Resources enforce boating laws alongside local and state law enforcement, and they can conduct vessel inspections to check registration, equipment, and operation. Fines are tiered:

Registration violations under KRS 235.230: $15 to $100, with each day of continued violation counted as a separate offense.⁴
Reckless operation or no-wake violations under KRS 235.420/235.430: $15 to $100 for a first offense, $100 to $300 for a second, $300 to $500 for a third or subsequent.⁴
Child life jacket violations under KRS 235.203: $50.⁴
Failing to obey a boating citation: $50 to $200, charged separately.⁴
General chapter violations: $50 to $200 where no more specific penalty applies.⁴

The individual fines are modest, but repeat offenses stack and a continuing registration problem counts as a fresh violation every day it goes unfixed. Boating under the influence carries the sharpest teeth, with jail time possible on a first offense and mandatory on a third.
