Jigsaw by Name , Jigsaw by Nature

As mentioned , Jigsaw's hulls are made from multiple sections  , each approx 5 meters in length and over 2 meters in width . These are required to be joined before they hit the water and the process of this joining has gotten more difficult since the decision was made to build in wood rather than steel . The connection points should be seamless , structurally sound and connect quickly  , not an easy proposal .

Skin connection is relatively simple , the inner skin of 12mm ply will butt up directly against its opposing section , the outer layer is held back 200 mm from this edge and a 400mm panel is fitted across this gap as the hulls are joined together , another layer or (butt block) is fitted on the inside of the inner skin across the 850mm distance between the transverse frames .

This gives 3 layers of ply with staggered joints across this section of the hulls , and is likely stronger than the rest of the hull .

Connection of the Chines , Stringers ,Keel and Gunwales is more complex as these are constructed of lamination's of solid timber , but again one of the lamination's is butt jointed to its opposing section ( outer piece this time )  , the inner lamination is scarf jointed with a additional section added and a inner reinforcing layer of fiberglass is added for additional strength in a U section covering the top and sides of each of the longitudinal structures.

The fiberglass U section provides a stronger connection than a third layer of wood as it attaches to a far greater surface area.
