[Public-List] Bulkhead repair

[Gordon Laco]

Good morning Greg, 

It’s considered best practice to have a relatively wide strip of dense foam between the edge of a bulkhead and the skin laminations of the hull.  The foam should  itself be glassed to the hull and the bulkhead with tabbing.   The idea is to spread the effect of a ‘hard spot’ from the bulkhead edge over a wider area than point (or rather line) contact.

I think you’ll find specific information in books on the subject
