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.

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."
