Ncik, the "Kelsall method" is not entirely unlike how the ply Blades are built only modified for composites.
Basic process is:
1. Pre-laminate Developed flat panels.
2. Stand the two (port and stbd) on a table with the deck shear line defined with blocks.
3. Join the panel on centreline
4. Force the cl down into the desired rocker.
5. Clamp into position.
6. add internal structure
7. add decks.
Despite what Bill seams to think it doesn't allow you to forgo a hull deck joint.
In reply to some other questions and comments up thread...
When strip planking with foam apply a layer of uni to one or both sides (depending on allowable stiffness) of the foam before cutting it into strips. This allows you to make full length strips and the added stiffness removes a lot of the issue with fairness and seams etc.
Your heated foam system is the way I would have gone too, if you set up a vac bag over the foam and increase the level of suction as you work you'll find it much easier to work the foam into the right shape. Obviously having a second person with a heat gun helps too.
