With the top mast outside and slugs instead of a bolt rope, the track
is no big deal. Internal is smaller, maybe not lighter, certainly
less peculiar.

Fair enough. I have not finished the boat yet, much less tried the rudders.

The boom is removable. For regular trailering, I would mount the boom
on a stub mast which stays on the boat, with the sails on it. The
mast is lifted up with a gin pole and inserted into the stub mast.
Feed in the slides and go sailing. The mast can rotate seperately
to the stub mast if you have a wing mast. This makes setting up much
easier.

Could be less, but not a big deal. I usually work on double the
draft at the ;ee hull bow with the ww hull flying.

Do this regardless of the length, it will make it all much less
stressful. Put a 40' load on your trailer and drive it rouns until
you stop knocking over light posts, school kids and little old ladies.
Then the 35 will seem very easy. ;-)

No, the deck should be 18" minimum width. But it can taper from this
straight down to the waterline width.

2"

Ta, won't be for lack of trying.
