Why Choose Fiberglass Pontoons?
Fiberglass pontoons offer a distinctive blend of longevity, versatility, and low maintenance unmatched by traditional aluminum or wooden pontoons.

Unlike wood—which is susceptible to rot—or aluminum, which can corrode and dent, fiberglass offers a robust, flexible, and lighter-weight solution. For houseboat kits, saltwater platforms, or custom marine applications, fiberglass pontoons are increasingly becoming the gold standard.

How to Choose the Right Fiberglass Pontoon
Assess Intended Use
Define if you need a platform for recreation, commercial activity, or full-time live-aboard use. Key features and performance metrics will differ between work barges, saltwater cruisers, and family boats.
Determine Size and Capacity
Length impacts stability and usable deck space. Roamer Marine Inc. and Southern Star Mfg offer custom lengths suited for everything from tiny homes to large ferries.
Consider Water Conditions
If boating in saltwater or brackish estuaries, prioritize models (e.g., www.beachcatboats.net) designed for corrosion resistance and impact durability.
Safety and Flotation
Pontoons with water-tight baffles (Roamer Marine Inc.) or internal bulkheads (Southern Star Mfg) provide redundancy in emergencies, preventing capsizing or sinking.
Budget: New vs. Used

Installation and Maintenance Tips
Professional Installation
While DIY is possible, heavy pontoons often require cranes or specialized lifting equipment. Professional fitting ensures alignment and secure integration into decks.
Sealing and Fastening
Ensure all mounting hardware is marine-grade stainless steel to eliminate corrosion risk. Properly sealed joints and fastenings prevent leaks and structural fatigue.
Regular Inspection
Check for cracks, blisters, or delamination of the gel coat. Routine cleaning with mild soap and freshwater prolongs finish—especially after saltwater use.
Storage and Mooring
Fiberglass pontoons can tolerate long-term outdoor exposure, but covered mooring reduces UV degradation and staining.
Repairs
Most surface scratches and minor punctures are repairable with marine-grade fiberglass kits. For structural damage, consult the manufacturer or an experienced marine technician.
