head room ?

I am building a sail boat for sailing > not around ?
you will not serve the proa principle ... if you are building it around a ball room !

on sailing .... you are mostly sitting on down to navigate to cook some thing or be sleeping to rest up !
and if you arrived at your dream environment in polynesia >
you can pitch your tent over your bridge deck > and have your ball room !

I am having standing head room im my 100' because there > its build in > not around !
and plan on going to some beach to land on > not some marina ....

so .... for what are you limiting your loa ?
they dont charge on beaches .... or anchoring on open road steads
but from your lenght on the water you are having a comfort greater then any head room can provide .....
