Schionning Cosmos 1320 FULL PELT
Description:

The Cosmos 1320 is a slim hulled and well proportioned performance cruiser which carries a comfortable payload of 2 tons. For many owners this boat will be the optimum size for cruising. She is long enough to carry a cruising payload without becoming heavily loaded - thus preserving good performance in all conditions and seakindliness in rough weather. Her low drag, slender hulls are big enough to provide spacious accommodation inside. However, she is small enough to have a size of rig that can be easily managed. Several commercial yards are building this popular model.

Building the Cosmos range
Plans for the Cosmos range of performance cruising catamarans are available for home builders and professional boat yards. The boats are strip planked in either Durakore (manufactured compound planks with a balsa wood core) or Western Red Cedar. With this method of construction the compound curves of the hulls and decks can be relatively easily accurately formed and building requires only a moderate level of skill and no complex or expensive tools. The result is a sleek looking, strong and light boat. Western Red Cedar is cheaper and a little easier to use but Durakore planking is about 30% lighter because of the significant weight saving in the core. The construction with Durakore gives a very high strength to weight ratio and will produces a lighter boat allowing either a little more performance perhaps for club racing, or a better payload for cruising.

Hulls are built separately upside down on temporary building frames. After being planked, the hulls are sealed with epoxy resin and glass, then turned by hand for sealing inside.
