Removable covering deck for the boat SEAWAVE prevents water from into the boat. Additionally, it offers easily accessible additional storage space. The deck attaches quickly and easily to the inflated boat with velcro. The SEAWAVE deck comes with four light metal reinforcements that help hold the shape and increase the stiffness of the deck and the boat itself. The deck also includes a plastic collar reinforcement that accommodates a standard spray skirt to make the boat completely watertight. The deck arrives with both types of reinforcements in a closable textile bag.
