Aluminum Fishing Boats
Aluminum fishing boats in Florida: welded vs. riveted hulls, best-fit rivers and lakes, saltwater corrosion care and a pre-purchase checklist.
Aluminum fishing boats are light, tough and simple, which makes them a common choice for Florida anglers who fish rivers, creeks and lakes or who want a boat they can launch almost anywhere. This page covers what they are good at, where they fit in Florida and how to judge one before buying.
At a glance
- Typical length: roughly 10 to 22 feet
- Built for: freshwater and sheltered-water fishing, easy trailering and rough use
- Typical crew: 1 to 4 people
- Common propulsion: outboard, from small tiller motors to mid-size console setups
What it's built for
The category runs from basic jon boats with flat bottoms and bench seats to modified-V hulls with consoles, casting decks and livewells. What they share is a hull made of marine-grade aluminum, either welded or riveted, that tolerates bumps against stumps, oyster shell and ramp edges better than many fiberglass boats.
Light weight is the core advantage. An aluminum boat usually needs less horsepower to get on plane, can be towed by a smaller vehicle and is easier to push off a sandbar. Small jon boats can even be launched from shorelines or primitive ramps where a heavier boat would be impractical.
Where it fits in Florida
Aluminum boats shine on Florida's rivers and smaller lakes. The St. Johns River and its creeks, the Suwannee, the Withlacoochee, the Peace River and countless smaller lakes across Central Florida suit a boat that is light, shallow and easy to handle around docks and fallen timber. Flat-bottom jon boats are popular for duck hunting and fishing in marshy areas where draft matters.
On the coast, aluminum boats are common in tidal creeks and backwaters along the Nature Coast and Big Bend, where shallow, rocky bottoms reward a hull that can take a scrape. Keep in mind that light, flat-bottomed hulls pound in chop and have limited freeboard, so big open water such as Lake Okeechobee in a north wind, Tampa Bay or any offshore run calls for caution or a larger boat. Always respect the capacity plate and check the marine forecast.
Some areas, including parts of the Everglades and certain waterways, have speed, motor or access restrictions. Check our environmental rules page before you go.
Pros and trade-offs
| Pros | Trade-offs |
|---|---|
| Light and easy to tow and launch | Rides harder and is louder in chop |
| Tolerates bumps on rocks, shell and stumps | Saltwater corrosion needs constant attention |
| Needs less horsepower to perform | Lighter hulls are pushed around more by wind |
| Simple layouts that are easy to clean | Fewer comfort features than many fiberglass boats |
| Good choice for shallow rivers and creeks | Riveted seams can leak as they age |
Ownership costs to plan for
Aluminum boats are often among the simpler boats to own, but costs still add up. The main drivers are engine size and age, how much saltwater use the boat sees, and whether you add electronics, a trolling motor and batteries.
Saltwater owners should budget time and supplies for fresh-water rinsing, sacrificial anodes on the engine and corrosion inspections, especially where stainless fasteners touch aluminum. Trailer upkeep, registration, insurance and covered storage round out the list. Florida sun is hard on seats and wiring, so a cover pays for itself over time. See boat maintenance and boat ownership cost for more detail.
What to check before buying
Before you buy
- Look for white powdery corrosion, pitting or thin spots, especially near the transom and keel
- Check riveted seams for weeping or loose rivets; fill the hull with a little water on the trailer if the seller allows
- Inspect welds for cracks on welded hulls
- Check the transom for flex and for rot in any wooden core or backing
- Lift the floor if possible to look for trapped water or waterlogged foam
- Run the outboard and check for steady idle, good water flow and no overheating
- Examine the trailer bunks and rollers; poorly fitted supports can dent aluminum hulls
- Match the hull identification number to the title and registration

Financing
Many aluminum boats are bought with cash, but a larger rig with a console and bigger engine may be financed. Use the Boat Loan Calculator to estimate a payment for the full package, and see Boat Financing for how boat loans generally work.
Frequently asked questions
Can you use an aluminum boat in Florida saltwater?
Yes, many aluminum boats are used in Florida's bays and rivers, but salt speeds up corrosion. Rinse the hull and trailer with fresh water after every trip, flush the engine and watch for contact between aluminum and other metals.
What is the difference between welded and riveted aluminum hulls?
Welded hulls are joined with continuous seams and are generally stiffer, while riveted hulls are joined with fasteners and are often lighter. Riveted seams can loosen and weep over time, so check them carefully on a used boat.
Are aluminum boats noisier than fiberglass boats?
They often are. Waves slapping the hull and gear dropped on the deck carry more sound through aluminum, and lighter hulls can ride harder in chop. Carpeting, foam and careful trim help.
