[Public-list] Bulkheads question

[Mike Lehman]

Don,

The main [forward] bulkheak is 3/4" teak both sides. The secondary bulheads 
are 1/2" also teak both sides. The bulkheads fit into the slots in the cabin 
liner and should be tight. The forward bulkhead has 'stiffeners' [mine are 
2x3 pieces of oak] attached to both sides. These are not straight up and 
down. The outboard stiffeners are angled. You may want to look at some of 
the pitures on the A30 website

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
