  • Patent number: 4781136
    Abstract: A safety cockpit for a powerboat totally separable from the remainder of the boat. The cockpit has a single wall between the interior and the exterior formed of a sandwich material of an Airex rigid foam to which are epoxied, on either side, two layers of Kevlar polyamide cloth. The removable cockpit section may extend only a portion of the length of the boat. In this instance, the boat then also includes two sponsons attached together to form a permanent deck; the cockpit then sits in a cavity formed between the sponsons in front of the deck. Alternately, the cockpit section may extend the entire length of the boat. In this case, a sponson attaches to each side of the nose section. The nose section also will then hold the engine powering the boat. In either event, the cockpit and the remainder of the boat only adjoin and connect to each other along vertical walls of each.
