A summer afternoon on the water ends differently than most people expect when a marine patrol pulls alongside. Washington enforces boating under the influence as a criminal offense, not a ticket, and the coastal waters around Westport, Ocean Shores, and Willapa Bay see real enforcement during salmon season, razor clam digs, and holiday weekends. The Rossback Firm handles criminal defense from downtown Aberdeen, and a BUI arrest is one of the more misunderstood charges that comes out of Grays Harbor County.

What counts as boating under the influence in Washington?

Operating a vessel while under the influence is a gross misdemeanor under RCW 79A.60.040(2). The statute reaches four situations: an alcohol concentration of 0.08 or higher, a THC concentration of 5.00 or higher shown by a blood analysis, being under the influence of or affected by intoxicating liquor, cannabis, or any drug, and being under the combined influence of alcohol and drugs.

A lawful prescription is not a defense. The statute says directly that being entitled to use a drug under state law does not answer the charge.

Reckless operation of a vessel is a separate offense in the same section and is charged as a misdemeanor. The two frequently appear together, and reckless operation is sometimes where a BUI case ends up after negotiation.

Does this apply to a kayak, a canoe, or a paddleboard?

Yes. Washington defines a vessel broadly enough to cover watercraft used or capable of being used as a means of transportation on water, with narrow exclusions for inner tubes, air mattresses, sailboards, and small rafts or flotation toys of the sort swimmers use.

That means a kayak on the Chehalis, a canoe on Lake Quinault, or a drift boat on the Humptulips falls under the same statute as a 24 foot charter boat leaving Westport. People are routinely surprised by this. The absence of an engine does not put a paddler outside the law.

Passengers drinking on board is a separate question. Nothing prohibits passengers from consuming alcohol on a recreational vessel. The restriction runs to whoever is operating.

Can you refuse a breath test on the water?

You can, and the consequence is different from a motor vehicle case. Washington added implied consent language to the boating statute in 2013. Anyone operating a vessel in this state is deemed to have consented to a breath test when an officer has reasonable grounds to believe the person was operating under the influence.

Refusing that test is a class 1 civil infraction under RCW 7.80.120, carrying a monetary penalty of up to $1,000. There is no license revocation attached, because a vessel offense is not a motor vehicle offense.

Blood is handled separately. When the arrest follows an accident involving serious bodily injury or death, or the officer has reasonable grounds to suspect drug impairment, a blood test may be taken with consent and a valid waiver, under a search warrant, or where exigent circumstances exist.

The handheld unit a marine officer carries on the boat is a screening device, not the evidentiary test the statute addresses. Submitting to that portable device is voluntary.

How serious is a BUI conviction?

A gross misdemeanor in Washington carries up to 364 days in jail and a fine of up to $5,000. The court may also order restitution for damages or injuries caused by the offense.

Unlike a motor vehicle DUI, the BUI statute does not impose mandatory minimum jail time, a mandatory ignition interlock, or an administrative license action. That gives a defense attorney more room to work on sentencing, and it is one reason a negotiated resolution can look quite different from a DUI outcome.

The absence of a driver’s license consequence is real but often overstated in people’s minds. The conviction still shows up on a criminal record, and employers running a background check do not distinguish between a boat and a car.

Will a BUI affect a future DUI case?

This is the consequence almost nobody sees coming. A conviction for operating a vessel under the influence counts as a prior offense under RCW 46.61.5055, the statute that sets DUI sentencing.

The practical effect is that a BUI from a July weekend on Willapa Bay can turn a later first-time motor vehicle DUI into a second offense for sentencing purposes. That shift moves a case from a mandatory minimum measured in hours to one measured in weeks, raises the minimum fine, and lengthens the license revocation. Anyone weighing a quick resolution to a BUI charge should understand that the plea is not self-contained.

Who is actually enforcing this on Grays Harbor and Willapa Bay?

More agencies than most boaters realize. County sheriff marine patrols handle much of the local enforcement, supported by the state boating program, and Washington Department of Fish and Wildlife officers have enforcement authority on the water as well. Along the coast, the Coast Guard operates in the same waters and applies its own federal standard.

Contacts often begin as safety equipment checks rather than as investigations. A marine officer coming alongside to verify life jackets, registration, and required equipment is a normal part of boating here, and the legal standard for that contact is not the same as the standard for pulling a car over on Highway 12. A conversation that starts with a life jacket count can turn into a BUI investigation quickly.

Enforcement also concentrates predictably. Opening weekends, the razor clam digs at Copalis and Mocrocks, the Westport charter season, and the Fourth of July all draw extra patrols.

When does a boating case become a felony?

When someone gets hurt. Assault by watercraft is a class B felony where serious bodily injury is approximately caused by operating a vessel while under the influence or in a reckless manner, and a death on the water brings a felony homicide by watercraft charge. Those cases move to superior court and are prosecuted very differently from a gross misdemeanor.

What The Rossback Firm examines in a BUI case

Boating cases have defense angles that DUI cases do not. Standard field sobriety tests were designed and validated for a person standing on solid ground, and a deck moving in Grays Harbor chop is not that. Officers sometimes administer seated tests or improvise, and the reliability of what they observed is a fair subject for cross-examination.

Fatigue is another factor. A full day of sun, wind, engine noise, and constant motion produces the tired, glassy-eyed, unsteady presentation that boating safety literature has long described, and that presentation looks a great deal like impairment to an officer who met the person five minutes earlier.

The rest is conventional defense work applied to an unusual setting. Was the person actually operating the vessel, or had someone else taken the wheel? What justified the contact and what turned it into a criminal investigation? Were the implied consent warnings given correctly before the breath test was requested? Was the breath testing equipment operating properly, and where was the test administered?

A BUI on the Washington coast is a gross misdemeanor with up to 364 days in jail, a refusal infraction that can cost $1,000, and a lasting effect on how any future DUI gets sentenced. It also carries defenses that do not exist in a roadside case, which is why these charges are worth examining closely rather than resolving quickly. The Rossback Firm defends boating and criminal cases for people in Westport, Ocean Shores, Aberdeen, Raymond, and communities across Grays Harbor and Pacific counties. If a day on the water ended with an arrest, a consultation before your first court date in Montesano is the right next step.
