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 .....
