Pat,

I have never done this but have an idea. If you can reach the forward bulkhead location from the cockpit, I think I would start with a piece of styrafoam -the old slightly crushable and crumbly kind. To get something stable I think you will need something at least an inch thick. Cut a couple holes in the center so you have something to grab to get it back out. I would cut he styrafoam bulkhead a rough slightly oversize shape then press it into place. It will crush against the inside of the hull and get you really close to a bulkhead pattern. You can easilly rasp it into shape if you dont get the fit right on the first try.

Once you have the styrafoam fitting well you can transfer the pattern to something thinner and harder to refine your bulkhead pattern.

: Hi
: I recently purchased a kayak but it has only one bulkhead and
: wanted to install a fwd bulkhead. In order to get a sizing for
: the bulkhead I marked the outside of the hull at the place where
: the bulkhead was to go with 1" intervals and using a spirit
: level measured from the level to the hull at the intervals.
: Results of the plot were poor so thought I'd see if anybody had
: good way of going about this!
: Many thanks
