 MAGNUM 12 CONSTRUCTION

MAGNUM 12 CONSTRUCTION

Just about anybody can build a boat using the Bowdidge Marine Design Plywood Composite system. This method eliminates many members that ordinarily require fitting, fairing, and beveling. Thus, it's ideal for beginners. A jigsaw and drill are about the only power tools required. The resulting boat is incredibly light weight, strong, and durable.

This quick and easy boatbuilding method consists of plywood planking panels cut to shape from patterns in the plans which are "stitched and glued" together at the seams. Such a boat can be assembled in a matter of hours after cutting out the parts.

Build method in summary:

  • Build the strongback
  • Cut hull parts and assemble onto the strongback
  • Glue together and then glass the hull
  • bog, fair ready for painting
  • Roll hull over
  • Glass the interior 
  • Install buoyancy foam for compliance to meet LEVEL flotation
  • Install seating and casting deck (optional)
  • Fit and glass the sole down
  • Install side decks and other optional fittings
  • Paint the hull
  • Launch day
