Thanks for excellent report!
I have been planning the same modification for our 3-cabin B40 (2001). My plan is to (as of now) to use a pair of Osculati Heavy Duty legs, as I want the table to be plenty of strong enough to slam onto in choppy weather. In Baltic Sea the waves may not be that high, but due to shallow sea the waves are often quite steep and I like the "cramped" interior design where we always have something to lean onto.
