One problem with that info is that it assumes all bulkheads are 
perfectly watertight.  Many kayaks have a teensy hole in the centre to 
allow for air pressure equalization.  I put one in both front and rear 
bulkheads after seeing the hatch covers bulging (Kayaksport rubber).  No 
amount of rolling or other wet practice has ever resulted in anything 
other than a bit of dampness in the compartment.

If you're really paranoid about leaks, Doug, you're gonna have a lot of 
fun with an SOF.  What with sewing seams making holes in the fabric that 
are sometimes too large (just) to completely close with paint or 
varnish, you're gonna have to decide whether you want a bit of a leak or 
go crazy finding and filling every possible hole.  Since the reserve 
buoyancy in an SOF comes from flotation bags and not the skin's 
integrity, it's really a moot point, IMHO.

With composite kayaks, I think you have to differentiate between a leak 
that constitutes a leak and one that constitutes a potential structural 
failure.  The small one of the former is annoying, a large one or the 
latter, dangerous.
