On FISHER^® Freedom pontoon boats, you get the best in a long-lasting deck with the optional PERMADECK^™ deck. This surface is made with tough marine-grade aluminum to withstand the challenges of the elements. Extruded aluminum planks are joined at the seams with foam to assure a quiet ride in rough chop. It won't absorb moisture or rot, and it won't warp or split from temperature or humidity conditions. And because aluminum transfers heat down through the pontoon tubes and into the water, you'll feel cooler, too. PERMADECK is backed by a limited lifetime guarantee to the original owner. See your local FISHER dealer for complete details.
