Default Tracing a pattern?

I'm putting in a bulkhead in a gutted power boat. I'm looking for info
on how to trace the curved surface of the hull vertically with the
chines etc so I get a close fit with the bulkhead material. If anyone
know any tips tricks or tutorials please let me know. Thanks

Use cardboard. Make yourself a very large compass (not the direction finding
kind but the kind that has a needle point on one side and a pencil on the
other)

Set up the cardboard far enough away from the sides of the boat you wish to
trace and use the compass to scribe a line on the cardboard by following the
sides of the hull chines and all.

Wilbur, This process is called "spilling" or at least it is on the
west coast boat yards.

That is because the spelling is wrong. Try 'spiling'. Only one 'l'

I added a partial (about half the beam) bulkhead to my fine bluewater
cruiser and that is the way I figured out how to fit it to the shape of the
interior where I put the bulkhead. The finish carpenters used this method
but on a smaller scale with store-bought compasses to fit teak trim in the
Irwin's when I worked there. I just scaled their method up. It worked great.
My custom bulkhead fits like it came from the factory that way. Never heard
the term "spilling."
