Re: Adding cabin to deck
I like Ike...but I'm a big fan of sorting these things out with out having to hire a Navel Architect...unless you have very deep pockets....and little construction or engineering scene.
There is a concern, as pointed out by Ike, that you could change the characteristics of the boat so much that it will no longer be stable..
I suggest visiting a boat yard and having a look at some cabin construction methods/details.
