It took a while but we have found time to carefully work through the lofting of the new proa.  The picture above shows the 3D solid model of the lofted boat. This includes details such as puzzle jointed butt joints between parts (rather than scarffs) and tabs on the frames with matching slots in the hull shells to help make the boat self-jigging.  The following image shows the nested parts:

The total nested materials are: (15) sheets 6mm ply, (11) sheets 9mm ply, (10) sheets 1/2″ 80kg/cubic m cross-linked PVC foam, (2) sheets 1/4″ foam, (1) sheet 1″ foam, mdf sheets for mold frames and some carbon cplate.

The appendages (daggerboard and rudders) have also been engineered and partially lofted.  Now we are on to producing the construction drawings for the boat!
