Buying a Used Boat in Florida: The Complete Guide

Before you start shopping

Buying a used boat in Florida is more involved than buying a used car. Florida is a non-titled state for most vessels under certain ages, hull condition can hide expensive problems, and sales tax rules are different from what you might expect. Spend an hour up front and you'll save yourself thousands.

Start by deciding how you'll actually use the boat. Offshore fishing 30 miles out is a completely different boat from family tubing on a lake or backwater redfish on the flats. Be honest about 80% of your trips, not the dream trip you'll do twice a year.

Set a realistic total budget

The purchase price is usually 70–80% of year-one cost. Budget for sales tax (6% Florida state + up to 1.5% county, capped at $18,000 for vessels), registration, insurance, a marine survey ($20–25 per foot), and any immediate maintenance the survey turns up.

If you're financing, expect 15–20% down on a used boat and rates 1–2 points above auto loans. Many Florida dealers have lender relationships that can pre-approve you before you commit to a specific boat.

Always get a marine survey

On any used boat over $15,000 — and any boat regardless of price if you're financing or insuring it — pay for an independent marine survey. The surveyor works for you, not the seller. They'll check hull moisture, engine compression, electrical, fuel system, steering, and run an oil analysis on the engines.

Find a SAMS (Society of Accredited Marine Surveyors) or NAMS certified surveyor in your area. A survey costs $400–$1,500 depending on boat size and is the single best money you'll spend.

The sea trial is non-negotiable

Never buy a boat you haven't run in the water. The sea trial should cover starting from cold, idling, holding RPM at cruise, hitting WOT (wide-open throttle), trim response, and steering at speed. Watch the gauges — temperature creeping up, oil pressure dropping, or RPMs that won't reach the manufacturer spec are all engine red flags.

Florida sales tax and registration

Florida charges 6% state sales tax on the purchase price, plus local discretionary surtax (varies by county, capped at $5,000 of the price). Vessels over $300,000 get a tax cap of $18,000. You pay sales tax when you register the vessel at your county tax collector.

Registration is required for any boat with a motor used in Florida waters. Bring the title (if titled), bill of sale, and ID. Annual renewal cost is based on length.

Red flags to walk away from

• Soft spots in the deck or transom (likely water-saturated balsa core — five-figure repair)
• Stress cracks at engine mounts, around fittings, or radiating from corners
• Oil with milky/foamy texture (water intrusion in the engine)
• Seller won't allow a survey or sea trial
• Title issues — liens, branded titles, or VINs that don't match documentation
• Recent paint over the hull bottom that wasn't disclosed

Buying from a dealer vs. private seller

Florida dealers add a markup but bring real value: warranty (often a 30–90 day powertrain), inspected used inventory, financing, trade-in handling, and post-sale service. Private sales are cheaper but you take on all the diligence and risk yourself.

For first-time buyers and anyone not comfortable with a wrench, a Florida dealer is almost always the better path. Browse dealer inventory on The Marina to see what's currently available across the state.
