They are all demountable.

There is a 400mm/16" step between the cabin floor and the bridgedeck,
so there is all round vision from the helm while standing, or with an
elevated chair.

5' wide hulls are fine, as long as the waterline is kept narrow.
Nothing less than 12:1 length to waterline beam. Once you know your
boat weight, this can be tweaked accordingly. Adding another 5'/1.5m
is a very cheap exercise.

It is great that you are getting your ideas on paper. It all looks
possible to me at first glance. The devil is often in the detail, and
this shows up with 3d drawings. I will do some of these when I get a
moment. Please remind me in a couple of weeks if I have not done
them. Possible mast height depends on speed required and weight.
Rare Bird's mast is a little under 18m/60' so 65' should not be a
problem for you. The booms can be raised to clear the hardtop. Hull
size will depend on the weight. Start making lists of what you want
on the boat and what it weighs and costs and we can work from there.
