The Spine has gone from 3 pieces to one, as the resin holding it together dries in my shed. 

It slotted together beautifully (although reading the post 'DC Designs' on Sailing Anarchy made me second guess the rocker - but then stuck with what  Geoff recommended....). The only real hassle was the $20 scales that would reset before we could add the hardener to the resin - FRUSTRATING.

We'll be dropping the spine into the mould tomorrow and then start cladding the mould with foam.
