G'day,

With our hull shapes, it may be feasible to use the same moulds for various
size boats. For example, an 18m/60' hull 2m/6'8" wide could have near flat
surfaces for the middle 3m/10' and near flat areras 300mm/1' either side of
the keel and deck join. To make a 15m/50 footer, 1.5m/5' wide, leave out
the near flat strips. This would mean an extra join lengthways, but thiis
area has heaps of reinforcing anyway, so this is not such a big chore.

Another option is to cut and shut the bows to make a 15m long hull from an
18m mould. Similar to constant camber methods.

Regards,

Rob
