Another option would be to fill between the bulkheads (between the bottom
and the floor) with expanding foam floatation. I'm not sure this would have
helped on the Titanic...

For each watertight compartment, figure the flooded waterline and make
sure the bulkheads are significantly higher (remember the Titanic).

Dear group,
I was recently cruising around the web looking at some shanty
boat plans, and noticed that none of the 5 or 6 plans i saw had any
bulkheads in the framing that would prevent the entire one piece hull
from filling with water should the hull be punctured. David Beede from
the Simplicity Boats website has a great concept design of a hull with
nice framing and plenty of beef to it. In the size of hull he drew, it
has a 4000 lb displacement with about a 4" draft. It would be a great
hull design. I was wondering if anyone had any advice for proper
placement of bulkheads in a shanty one piece hull. This would be much
easier to build than individual pontoons with bulkheads. Any thoughts?
Thanks..
