What's the theory on reverse stems / ware piercing bows?

Originally posted by JimC Originally posted by iGRF Can't they just power staple them Ordinary staple gun staples are invaluable, but for a lot of boat building jobs they don't have the muscle to hold stuff down. Large mechanical fastenings that would have the muscle leave undesirably large holes in the wood when you remove them. Hence you end up with loads of clamps. Plastic staples which you don't have to remove ought to be a good thing, but I haven't tried (and I'd forgotten about them when I just bought a big box of staples).

Got it Good tip that, who wants to mess about with glue when a power stapler with light none rust nails would do, this is good, I'm feeling a trip to the man cave tonight to work out layout.

There are also proper nails made of plastic, one thing I can wield is a hammer, nod your head and I'll hit it..

But seriously I was thinking get it assembled then epoxy glass the leaky bits and the bits you kind of really want to stay stuck together and epoxy varnish the rest.

It's a bit of a weird shape that my main worry would be a fore and aft total snap in two failure, it wouldn't be the first time I built a boat which fell in two the moment I put it on the plane, being the first johnny to try and laminate kevlar we found out it's lack of resin absorption properties the hard way..

I can see straight stems maxing WLL to LOA and I guess I can see how the fine, very deep vertical bows on Cats work, preventing nose diving like the old Tornado and offering some resistance to leeway. What is the benefit of coming back past vertical, weight saving for max WLL seems possible but minimal to me. Is going through a wave thought to use less energy than lifting the boat and crew weight over? When you go through don't you increase wetted area and displace more water than going over, chucking spray up and around must be wasted energy as well. Not arguing, just asking.

Plastic, Modern composite nails, nails that melt when you heat them up, nails that can be sanded away, I think they're a blinding idea, I read somewhere in all the blurb that they are used for modern boat building.
