Construction
Built from marine or boatbuilding plywood and completely fibreglassed in an epoxy matrix both inside and outside, the Magnum 12 is designed for very easy building: no compound curves, no unnecessary complications, ease of construction, easy maintenance and a long life.
The 3/16" (4mm) panels, cut flat from our expanded plates dimensioned drawings, are bent around the frames and fastened to the transom and bow with stitches
The plans show all dimensions needed for each method: accurate expanded plates dimensions and all bulkheads and transom dimensions with spacing for building on strongbacks if desired.
With no lofting, beveling or scarfing required, the sides and bottom panels are cut from standard 8x4 plywood (1.2m x2.4m) and joined with a simple fiberglass butt block. All seams are then taped with fiberglass and epoxy (see our "Boatbuilding Forum " section for details.) As these epoxy joins are much stronger than the plywood, the assembled hull is then completely fibreglassed for extra strength and easy maintenance, resulting in a boat with less maintenance and a better finish than a production fiberglass hull.
Required Skills:
All our stitch and glue boats are easy to build. No woodworking skills or special tools are required. The plans include all dimensions and patterns to cut all the hull parts flat on the shop floor.
Materials
The following list of materials is approximate and intended for calculation of approximate costs. We offer no guarantees of accuracy. The list is for all timber in the construction of hull, deck and interior, including building stocks, temporary bracing etc. Allowance has been made in the quantities for about 10% wastage. These figures allow for building with 3/16 in (4mm) Marine Ply for the hull and side deck, 1/4 in (6mm) plywood for the bulkheads and joinery and cockpit sole. Resin & glass quantities are only approx.
