Can You Get a DUI on a Boat in Florida?

Many people are surprised to learn that Florida law treats boating under the influence (BUI) almost identically to driving under the influence (DUI). With hundreds of miles of coastline, the Intracoastal Waterway, and countless bays and rivers across Northwest Florida, BUI arrests are more common than most people think — especially during holidays and fishing season.

What Counts as BUI in Florida?

Under Florida Statute §327.35, it is illegal to operate a vessel while impaired by alcohol, a controlled substance, or a combination of both. The legal blood alcohol limit is the same as for driving: 0.08% BAC. "Vessel" includes motorboats, sailboats, personal watercraft (jet skis), and any other craft used for transportation on water — except seaplanes.

BUI Penalties

BUI penalties in Florida mirror DUI penalties closely:

• First offense: Up to 6 months in jail, fines up to $1,000, and possible probation
• Second offense: Up to 9 months in jail and fines up to $2,000
• Third offense (within 10 years): Third-degree felony — up to 5 years in prison
• BUI with serious bodily injury: Third-degree felony
• BUI manslaughter: Second-degree felony — up to 15 years in prison

Unlike a DUI, a BUI conviction does not result in a driver's license suspension. However, it does go on your criminal record and can affect employment, professional licenses, and future sentencing if you are ever charged with DUI on land.

How BUI Stops Work

The Florida Fish and Wildlife Conservation Commission (FWC) and local marine patrol units have broad authority to stop and board vessels for safety inspections — no probable cause required. During these routine checks, if an officer suspects impairment, they can conduct a BUI investigation including field sobriety exercises (modified for the marine environment) and breath testing.

This is a key difference from traffic stops, where officers generally need reasonable suspicion to pull you over. On the water, they can stop you at any time.

Defending a BUI Charge

Many of the same defenses that apply to DUI cases also apply to BUI cases:

• Challenging the accuracy of the breath test and the maintenance records of the testing device
• Questioning whether field sobriety exercises were conducted properly — conditions on a rocking boat are very different from a roadside
• Challenging the officer's observations and conclusions about impairment
• Environmental factors: sun exposure, fatigue, sea conditions, and dehydration can all mimic signs of impairment
