In my mind there is little doubt that the stitching part of stitch-and-glue is a somewhat tedious process. Yes, it allows quite complex shapes to be developed, yes, it is not all that difficult, etc, but…. Pondering this, I cannot help wondering if there is an alternative for a built-from-sheet-ply design. Let me float this concept:
- forms are cut to the external cross-sections of the hull at regular stations (say every 12”);
- forms are mounted on a strongback to give the outside of the hull shape (does this make it a male or a female mould – I never can tell the difference!);
- ply hull panels are cut to pretty accurate shape (same as with normal S&G);
- the panels are temporarily fixed (screwed, stapled?) inside the forms and adjusted to a close fit along all chines;
- no stitching is done along the whole length of the bottom and side panels*.
- filleting is done inside the hull right along all chines;
- fixed bulkheads are added;
- internal taping over fillets, and external glassing, then proceeds as normal;
- * I accept that some stitching may be necessary at the vertical bow and stern joints.
