The kefring worked great. I only had to kerf the keel from the bow back 1200mm.
This gave a very smooth curve. I'm currently busy preparing the foam to take a vacuum for the laminate. I'll post some pics when I get a chance.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
