    What thickness is your lay-up either side of the core?? Also are you using poly, vinyl or epoxy?? The hull stringers look fine, try to put a 30-50mm radius where the bulkhead attaches to the hull, then re-inforce it with laminate. Not necessary, but does make it stronger. Otherwise she looks good!
    Have you built boats before?

    Looks like you will still want to radius and tape at least a couple of layers where frames and stringers contact hull. One very important aspect is prevention of water ingress into wood parts. This can't be too strongly emphasized as repairs to rotton wood framing is quite common, though preventable if ALL surfaces including faying (wood to hull or other wood) is also well coated. Epoxy is far better in this respect than polyester resin and it will extend the life of that wood. The stringers can be bedded in thickened epoxy and three coats of plain epoxy should be painted on all the bare wood surfaces.

    Foam stringers are better of you give then some shape and really have to think about the glassing and the glass to use . Stringers first and glassed over and then the bulkheads fitted and coved and glassed in place !!.
    Tell me how you would go about all i have just written . I will be back in circulation again in a couple of days am 10000ks away from home !!:D

    Just need to think a little !

    Bulk heads and internal framing is forming a skeletion and its how everything is attached thats the key to making it all work as one structure . To much galss or to little or even the wrong kind of glass and you created a stress point that will eventually fall apart just when you really dont want it to or If its a hard point could even damage the outer hull skin to the point of punching a hole through it because you didnt do the job properly !!.:confused:

    only problems using plactic pipes is the noise of everything moving about inside and make sure you have holes in the bottom for water to get out . leave nothing to chance !!
    The flapping sound of cables could piss you off maybe !!its not a good idea at all !!have been there done that and we ended up drawing all the cable looms out and covering them with bubble wrap to shut out the sound !!:eek:.
