De-foaming hulls to remove waterlogged foam?

Has anyone tried to remove the waterlogged foam from the SJ hull?
Anyone have an idea of how much the wet foam may weight?
A guy on X.h2o Quoted he got 65 lbs of wet foam out.
It looks like a major job if it only removes 2kg of water.

Talk to rickxp about that....Hes the man at defoaming superjets lol.

I did the exhaust side of my hull and got a lot of water out but probly wasnt worth the hassle, just hit the waves faster.
