Hi James,
the frames shown in my plan indicate the real otter shape of the hull,
that means with all the plates and everything. When you build up your
hull and add the ship side to these bulkheads, without substracting the
thickness of the ship side, your hull would get fatter as it should be.
So before you copy the frames onto your piece of wood, you have to think
about how to build up the ship side, how thick will be the ground layer
of wood, how thick the layer of fibre glass and so on and at the end you
draw the frames onto the piece of wood without this thickness, this
means smaller.
I noticed this on the plan, it is written somewhere. The reason for this
is, that there are different methods to build up the hull.
I bet you didn't substracted it, if you would have done this, your frame
143 wouldn't reach all the way down to the keel. As I said before, the
frames are templates!!! you have to put a little work in them to get out
your frames, for your methode to build the hull.
Hope that helps, check this please and mail me back.
