Wilderness 930

Home-built from plans

Brand:: Schionning

Designed by:: Schionning Designs

Description:

The Wilderness 930, with a payload of 700 kg (~1500 lbs) was designed for weekending, short cruises or 'lightweight' liveaboard. With a hull length-to-beam ratio of 13:1 she can be raced reasonably effectively if kept light. Loaded, she has a very good cruising performance. The well proportioned bridgedeck cabin is low, with 1.5 m (~5 ft) headroom, keeping the windage low and giving excellent visability from the helm. The hulls have standing headroom. There is an access door on either side of the cockpit so it is just a short distance through the saloon to the stairs, when it is necessary to crouch. Plans are available from Schionning designs or their agents. No pre-cut kits are available for this model.

The Wilderness Range
The Schionning Wilderness range of cruising cats is especially designed for simple and quick home or professional construction. Most of the boats, including the hard chine hulls and the furniture, are built from joining ready-made, pre-glassed balsa or foam cored flat panels, for example, from DuraKore. These can purchased as pre-cut kits, available in several options, for most models in the series.

The range has good load carrying potential as fits its purpose as a cruiser, yet hulls are slender enough at the waterline to give a very good speed potential. A generous bridgedeck clearance helps avoid slamming when sea conditions deteriorate. The hulls are flat bottomed, as natural in a chine catamaran construction. The flat run aft encourages planing – but the bottom panel is Veed forward to prevent noisy under-hull slamming. The hulls are also flared forward, on the inside, giving additional buoyancy reserve and thus more safety at sea. The flare also helps to deflect spray from reaching the decks.

Though built mainly of flat panels, the Wilderness range does not have the angular look of a chined boat. Compound curves are strategically incorporated both to improve appearance and to reduce air drag. The deck sections are strip-planked using the already constructed parts as a mould; this allows the decks to be rounded on the turn of the hull. Strip planking the bridgedeck cabin roof also produces similar beneficial curves.
