BASIC CONSTRUCTION: is similar to our Marc 1 series with ³/₈" sheet ply bottom over 1 x ⁷/₈"., stringers four a side on the bottom with ⁷/₈¹¹ square stringers two a side on the topsides. The craft has laminated chines, keel and gunwales with the rims sawn from ⁷/₈^" timber. The planing area of the bottom is framed at 2'6" centres with two laminated ribs between the frames. These ribs are formed with three laminations 1 x ³/₁₆" and are screwed and glued in after the hull is turned over. This forms an extremely strong bottom construction which allows the craft to be driven at high speeds in rough water.

FULLSIZE PATTERNS: are supplied with the plan for all frames, stem, rims and transom plus detailed drawings of all hull con­struction and written instuctions on building procedure.
