I am not a big fan of kevlar on shorter boats at least on white water boats because it does not save much weight/cost. However I think it would be really good on longer boats like yours. My only experience with composite layups is from whitewater boats which are subject to different stresses. I would guess that the book mentioned would be an excellent source. All the pure kevlar layups I have seen have used structural foam vacumbagged in the layers to add stiffiness where needed. Personally to avoid the cost of potential screwups I would mix kevlar, glass and maybe poly to achieve a happy medium between cost/weight. Walbridge's Boatbuilders Manual has lots of info on this too. John Sweet and Paul Schreiner would also be excellent resources as to layups. When you are vacum bagging, I think it is a little easier to accuratley estimate the finished weight. Again so much depends on if you want an ultralite or a expedition freighter layup....

: My paddling partner and I are thinking about taking a one-off from my new
: Guillemot 18. Yes, *gasp*, I'm actually contemplating smearing a bunch of
: epoxy and glass/kevlar/cf all over a bright, shiny, new boat!!

: We're thinking about laying up the fabric over the bottom of the well-PVA'ed
: hull, and then vacuum bagging it. We'll do something similar for the deck,
: and then still probably build a wood coaming, since it would be hard to do
: a one-off from a completed coaming.

: Deck and hull will be cut at the original sheer line, after removal from the
: wood boat, and then seamed "normally".

: Big question: any recommended compositing schedules out there? He'd like to
: use primarily kevlar, but we'd consider some glass or carbon for ease of
: layup or what not.

: He doesn't have the time/patience/skill to do a stripper, and doesn't like
: any of the existing s&g designs. Oh yeah, and he can't afford to have me
: build a stripper for him!
