I have the same problem. I am 6'4" and living on my
boat with only 6' headroom. I started a thread today throwing out the idea of raising the
hull and
deck to add the room. Replies so far have been negative on the thread, but mostly because no one has done it and most think it is too much
work and cost. I am not so sure about that, but will continue the
research.
I have also started a conversation with a naval architect and custom boat
builder this morning who was recommended and he thinks it is very doable and will not affect stability too much. He has requested boat pictures and will help me decide if I am to go forward with it.
Granted each boat has it's own unique attributes which would affect this option.
Mast going through
deck or not, how is
rigging attached, are walls all covered with cabinets and
wood, etc. Mine has all ideal details for this
project.
Just something to consider.
