By now you should have your deck and cabin top camber pattern prepared.   If you have not already done this look at your plan and transfer the measurements for the deck widths, cabin lay-in, cabin heights etc., on to the bulkheads.   Mark out each bulkhead ready to receive the decks and cabin structure.

   It is a good idea to cut several temporary camber boards to be used as intermediate supports for the cabin and deck during construction.  As it is unlikely there will be enough bulkheads to support the deck structure while you are moulding it in place or, bonding on a pre-laminated section, these camber boards should be installed until the deck and cabin are complete.   Temporarily fasten the camber boards to the deck shelf and they will then either support the hardboard form work that makes up the in-place mould, or the parts of the pre-laminated deck as mentioned above.
