: So what's the solution? I have yet to see any skin boats with bulkheads! How
: would one be installed amongst its numerous ribs? What about access ...
: how would a hatch be installed?

Take Shawn's and Matthews floatbag, drybag ideas and construct a large airbag/drybag w/ a pvc bulkhead end (or pvs perimeter) right behind the seat. Instal a hatch in that bulkhead and you have some skin redundancy, as well as fairly ok access. If the bag was really robust you could maybe(probably not) start pulling it all out as the gear was half unloaded.

For the front, maybe you could make drybags that were slightly smaller that the inner circumference and jam in place w/ a typical front airbag. Let out the air in the airbag and pull out the drybags. Maybe even a perimeter bulkhead to keep all in place.

Or make a net bulkhead that clips to the frame but doesn't let the airbag move forward, and really mak it bulge.

And those who like saving money, sitontops and structural expression combined, what about finishing the frame and only using airbags inside the yak and dispense w/ the skin altogther. Sure would look cool, tho a might slow.
