SeaDek Flat Fenders: Premium Protection for Your Boat
Protect your boat with style and efficiency. SeaDek’s Flat Fenders are designed with high-quality closed-cell EVA foam, offering durable defense that won’t deflate or deform.
Unlike traditional fenders, their low-profile rectangular design prevents them from rolling on the hull, ensuring that protection always stays in place without leaving marks or generating noise when colliding with docks or other boats. They are the perfect solution for saving storage space: lightweight, compact, and ready for action.

Innovation in Protection: Why Choose SeaDek Flat Fenders
SeaDek flat fenders represent the logical evolution in boat protection. Unlike traditional inflatable PVC fenders, which tend to roll and shift, leaving the hull exposed, our Flat Fenders maintain their position thanks to their non-slip rectangular design. Manufactured with our exclusive closed-cell EVA foam, they offer progressive cushioning that absorbs impact energy without bouncing.
In addition to their superior performance in docks and moorings, their greatest advantage is storage. Their flat profile allows them to be easily stowed under cushions, in narrow lockers, or stacked, freeing up vital space on deck. They are the preferred choice for sports boats, tenders, and racing sailboats where weight and space are critical. Being 100% customizable, they not only protect your investment, but also extend the aesthetics of your SeaDek deck to the waterline.
FAQ - Frequently Asked Questions
Why should I use flat fenders instead of round ones?
Round fenders have a main problem: they roll. When moving, they leave the impact point unprotected. SeaDek flat fenders “stick” to the hull, covering a larger surface and ensuring that protection is always where it is needed. In addition, they take up almost no space when stored.
Are they suitable for any type of boat?
They are extremely versatile. They are ideal for mooring in low docks, for rafting (tying up to another boat), or as a protective “cushion” in delicate maneuvers. They are very popular in speedboats, fishing boats, and as auxiliary fenders in large yachts.
Do they float if they fall into the water?
Yes, absolutely. They are made of closed-cell EVA foam, which means they do not absorb water. If they fall overboard, they will float indefinitely and will not become heavy from being wet.
Can they scratch the gelcoat or paint on my boat?
No. Unlike dirty rubber or hard plastic fenders that act like sandpaper with movement, SeaDek foam is soft to the touch and gentle on the hull finish. They protect without leaving abrasion marks.
Can they be personalized with the name?
Yes. We can mill your boat’s name, home port, or logo directly into the fender, offering a premium and permanent finish that will not erase.
How are the fenders cleaned?
They are cleaned the same way as your boat’s floor. Fresh water, neutral soap, and a soft brush are enough to remove salt and dirt. They are resistant to common stains in the marine environment.
