Boating Under the Influence (BUI)
Few places in Florida mix boats and law enforcement like our water: Lake Tohopekaliga (“Big Toho”), East Lake Toho, Cypress Lake, Lake Hatchineha, and Lake Kissimmee — the Kissimmee Chain of Lakes — draw bass tournaments, airboats, and weekend flotillas year-round, and with them FWC officers and sheriff's marine units running safety inspections that turn into BUI investigations. Here's what most boaters don't know until the handcuffs: a BUI carries the same fines, the same jail exposure, and the same felony escalations as a DUI — and it lands on your criminal record just the same.
What's different are the rules — and the differences are where BUI defenses are built. If you were arrested on the Chain, on Lake Cecile or Lake Runnymede, or anywhere on Central Florida's water, call or text 407-846-8008.
BUI Penalties Under § 327.35
Operating a vessel with normal faculties impaired or a breath/blood alcohol level of .08+:
• First conviction: $500–$1,000 fine, up to 6 months in jail;
• Second: $1,000–$2,000, up to 9 months — with a mandatory minimum 10 days in jail if within 5 years of the first;
• Third within 10 years: a third-degree felony, with 30 days' mandatory jail; a fourth is a felony regardless of timing;
• Enhanced tiers for a reading of .15+ or a minor under 18 aboard — a detail that catches family-pontoon cases;
• BUI with damage or minor injury: first-degree misdemeanor. Serious bodily injury: third-degree felony. BUI manslaughter: a second-degree felony with a 4-year mandatory minimum — and a first-degree felony for leaving the scene or for operators with prior DUI/BUI-manslaughter-type convictions, under 2025's Trenton's Law changes.
• Prior DUI convictions count in the BUI ladder (and vice versa) — your driving record follows you onto the water.
• A conviction also brings the DUI-style package of collateral terms: monthly-reporting probation, a required substance-abuse course and evaluation, community service, and vessel impoundment provisions.
Florida also toughened boating-crash laws in 2025 (“Lucy's Law”), including felony treatment with a mandatory minimum for leaving the scene of a fatal boating accident. The water is not the forgiving jurisdiction it used to be.
How BUI Is Different From DUI — and Why That Helps the Defense
• No suspicion needed to stop you. FWC can board for safety and registration checks without any traffic-stop-style justification — which sounds bad, but means the investigation's escalation (why did a life-jacket check become a BUI probe?) gets scrutinized instead.
• Your driver's license is not suspended. A BUI doesn't trigger the DMV machinery — no 10-day rule, no hardship license fight.
• Refusal rules are gentler — and widely misreported. Unlike driving — where a first refusal is now a crime — refusing a breath test after a BUI arrest brings a $500 civil penalty; refusal becomes a misdemeanor only with a prior. (Much of the internet, and some lawyers, have this wrong since the 2025 law changed the rules for drivers only.)
• “Normal faculties” look different on water. Sun, heat, dehydration, hours of engine vibration and glare — “boater's fatigue” — mimic impairment cues, and the “field sobriety” exercises done seated on a rocking deck or at the ramp are even less reliable than roadside ones. Juries who boat understand this.
• “Operation” is an element — and a fact fight. Florida defines operating a vessel broadly: being in charge of, in command of, or in actual physical control of it. So anchoring or killing the motor doesn't end the question by itself — but rafted-up, anchored, and sandbar scenarios on Big Toho make who was in control, and when, genuinely contestable in a way “who was driving” rarely is.
The Osceola Reality
Expect heavy enforcement on tournament weekends, holidays (July 4th on Big Toho above all), and night operations at the ramps — Big Toho Marina, the Kissimmee lakefront, Granada and Whaley's Landing. Officers are polite, the “safety check” is friendly, and every answer you give is evidence. Be courteous, hand over what's required, and decline to narrate your day on the water.
Frequently Asked Questions
Can I drink at all while boating in Florida?
Passengers can. Operators may lawfully drink too — the crime is impairment or .08+, not an open container. The practical line: if an FWC officer boards, your coordination and answers are being graded from “hello.”
I was anchored at the sandbar, not driving the boat.
Anchoring alone doesn't defeat the charge — Florida's definition of operation reaches being in charge or in actual physical control — but it opens a genuine factual fight about who was in control and when. Don't concede it at the scene by narrating; identify yourself and stay quiet about who was running the boat.
Will a BUI affect my driver's license or CDL?
It doesn't trigger the administrative license suspension a DUI does — but as a criminal conviction it counts as a prior for future DUI/BUI charges and shows on background checks. CDL holders should get specific advice.
Do BUI cases get reduced like DUIs?
Yes — the boating equivalents of reckless operation exist, and the proof problems above can make reductions and dismissals realistic with a real defense.
