The Intex® Mariner is the perfect boat for the hardcore camper or fisherperson, as well as for anybody looking for a high quality, durable boat. The Mariner is GS certified. It is constructed from Intex’s® three-ply SUPER-TOUGH™* vinyl. Two outer layers of heavy-gauge PVC are laminated to an inner layer of polyester mesh. Not only is this extremely tough but it allows for a more rigid hull. When combined with an inflatable keel, all around rock guard and grab rope, rotational oar locks, motor mounts, fishing rod holders, grab handles and a rigid floor, the Mariner is in a class by itself!
