<p>Each craft may be assembled from a number of hulls (1) of similar shape and size. The hulls are joined together by fixed brackets (3) which have cross members bolted together to extend over two or three hulls are required. The brackets are joined together with longitudinal members to form a rigid rectangular frame. Each frame is fixed to the hull and a number of frames may be used to cover the length of the hull. The hulls may then be adapted to rowing with the mounting of outriggers, or to sailing with the mounting of a mast, or to a powered design with the fixing of an outboard motor.</p> |
