SeaDek is made from thin EVA foam which is UV stable and is easily maintained and stain resistant. Not only does it give you a non skid surface it is soft to touch and if you fall or rub your knee on it it wont hurt or scrape. Its a bit like neoprene to the touch and compresses when a load comes on it, so impact is softened.
There are more advantages; SeaDek’s impact absorbing surface lessens fatigue. Many powerboats use it under the helm station so the drivers feet are cushioned. Cockpit coamings are also a favorite as leaning against SeaDek is more comfortable than a hard gel coat surface.
