thanks to the folks who provided feedback on my lofting question.

Im going to build the ranger {15'} instead of the prospector (16')
canoe, and im going to construct it with a kevlar-carbon layup instead
of wood strip. Can anyone suggest the best way for me to adjust the
size of the stations to accomodate the thin, uniform thickness of the
composite layup compared to the wood. I'm going to use 3 layers of
5oz kevlar and one or two layers of unidirectional carbon so im
guessing it will be about 1/8"-3/16" thick max. how thick is the wood
stripping and is it relatively uniform in thickness ie can i just add
1/2" to all my patterns and have a decent work around?

also i would like to not use foam core in my layup for simplicity and
minimizing weight...but will the canoe sink like a rock if its swamped
if its just kevlar/carbon/epoxy? I am wondering if i should use a
1/8" atc core cell between layers of kevlar...for buoyancy and
stiffness.

Lot of guessing and questions there that would suggest you have a
bunch of R+D to do before you start spending loads of money on Kevlar
construction. Personally I would build a couple of smaller less
complicated vessels or do a bunch of testing on kevelar and foam layup
first to start to get a feel for the materials, techniques, and other
talents necessary for the type of construction you are contemplating.
This will also answer or negate a lot of your questions above. And if
nothing else, break down and get a good set of plans or a good book
for a tried and true design so you have something to refer to, or
better yet, someone to call if you have any questions or problems.
I am not trying to be an ass here, and I have been watching your
threads, just being honest and trying to save you a lot of time,
frustration, and money, hope you understand.
