KEMIMOTO Boat Fenders for Docking Gray, Extended 2 PCS — Thick Closed-Cell Foam with Quick-Lock Straps

KEMIMOTO Extended Gray Boat Fenders are a two-piece, non-inflatable dock bumper set designed to protect hulls and gunwales for 15–25 foot boats during docking and mooring.

These upgraded boat fenders combine an enlarged, thickened closed-cell foam body with reinforced nylon straps and a quick-lock installation system. Built to resist sun exposure and abrasion, they eliminate the hassle of inflation and reduce the risk of air leaks while giving broader coverage where your boat meets the dock or another vessel. The set is particularly suited to low-freeboard watercraft such as bass boats, jon boats, pontoon boats and small fishing vessels.

How do these fenders protect my boat when docking?

The wider, thicker foam profile increases the contact area so impacts are distributed rather than concentrated, helping prevent scratches and dents along the hull and gunwale. The closed-cell foam resists water absorption and sunlight degradation, keeping the bumper buoyant and effective over time.

• Widened, thickened cross-linked closed-cell foam for expanded impact coverage
• Non-inflatable design removes leak and pressure-failure concerns
• Durable materials resist UV and saltwater exposure
• Protects both hull sides and gunwales on low-freeboard boats

What makes installation fast and secure?

Each fender uses an integrated strap with a fixed buckle so you lock it in place fast without complicated knots or tie-offs. Reinforced nylon rope attachment points add extra strength and keep the fender stable even in windy or choppy conditions.

• Integrated strap and quick-lock buckle for tool-free installation
• Reinforced nylon rope and secure fixings for storm resistance
• No inflation needed — ready to mount straight from the box
• Designed to stay in place during docking maneuvers and light contact

Which boat sizes and types work best with these bumpers?

KEMIMOTO recommends the extended fender for boats between 15 and 25 feet long and suggests one fender per 10 feet of boat length; for craft under 30 feet, use at least three fenders for full-side protection. The compact, wide shape suits low-freeboard boats that need extra gunwale coverage.

• Ideal for bass boats, jon boats, pontoon boats, ski boats and small fishing boats
• Suggested ratio: one fender per 10 feet of boat length
• Use three or more fenders for boats close to 30 feet for continuous protection
• Works well on docks, pilings and alongside other boats

How durable are these fenders for long-term use?

Manufactured from cross-linked closed-cell foam, these bumpers resist compression, waterlogging and UV damage better than standard air-filled options. The robust construction and reinforced attachments reduce wear under repeated collisions and harsh weather conditions.

• Cross-linked closed-cell foam resists water and sun damage
• Thickened body keeps shape after repeated impacts
• Reinforced straps and buckles reduce failure points
• Low maintenance: no pumping, patching or pressure checks

Who is this for: KEMIMOTO Extended Gray Boat Fenders are made for boat owners who want reliable, low-maintenance hull protection without dealing with inflatable units. They’re a strong fit for anglers, weekend boaters and pontoon owners who need broad coverage for low-freeboard boats and prefer quick, secure installation. If you’re outfitting a 15–25 foot watercraft or planning a set of three fenders for a boat under 30 feet, these bumpers deliver straightforward protection and long-term durability.
