Cosmos 930

 Home-built from plans or kit

Designed by:
Schionning Designs

The Cosmos 930 is a compact, ocean capable cruiser with a serviceable payload for cruising (800 kg /~1760 lbs). With her light, slim hulls she can sail fast, and strip planked in cedar or Durakore, she is a viable project for home builders.

There are three main versions of the 930: with open bridgedeck; with a full bridgedeck cabin; and with an open sided bridgedeck cabin. All versions have the same dinette layout on the bridgedeck, with the cabin on top, the headroom in this area is 1.6 m (5 ft 2 in). A soft bimini cover can be used on the open top version, and the open sided version can be fully enclosed with 'zip in' flexible windows.

There is standing headroom in the centre of each hull for the galley and head and shower compartment. There is a double berth in the stern of each hull with sitting headroom, and a 'dive in' bunk in each bow.

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.
