: Need to ask for help from those with more experience. I am building
: a CLC Arctic Hawk, nearing the time to put the deck on at last.
: Instructions call for a 3/32" hole to be drilled center top
: of both bulkheads to vent pressure.

I put a 2 mm hole in the centre of the bulkhead (not top). This should place the hole above water which ever way up the kayak is. The holes are for pressure relief. A hot kayak on the beach being dropped into cold water (when launched) has to do something to the internal air pressure.
