[Public-list] Bulkheads question

[Don Lang]

The vessel I have has no bulkheads installed.
Can anyone tell me the thickness they should be?
I have read (elsewhere) differing opinions on whether the bulkheads should be fastened to
the deck or not. Many production vessels stop the bulkheads short of
the deck to prevent deck fractures and stresses. I'm not sure what to
do in the case of the Alberg 30. 
I understand that its best to mount the bulkheads on say 1/4" or 1/2" of rubber (or other flexible material) so they are
off the hull thus not creating hard spots (that tend to flatten the
hull and create fractures under load) when the bulkhead flexes and instead rely
on the tabbing to spread the load.  I plan on using 4" & 6", biaxial cloth
and west system epoxy for the tabbing and overlapping the cloth in
layers to spread the load. Should the tabbing be continuous or only every ?? inches.
As  my boat is an empty hull I have no way of knowing what was there and how it was installed.
All suggestions and opinions are greatly appreciated.
Best regards, Don #473
