Hi
If the boat is designed to sail, stability without a mast and sails will not
be a problem. In most cases you will want to remove some ballast to reduce
stability and slow down the roll period. But it is sensible to talk to a
designer about how much you can remove.

Denny,
Following sugestions from this group, I did a little online shopping today.
Powerboat hulls just don't seem like good candidates to me. Even small
trawlers have engines in the 100HP range. I switched back to sailboats and
found a couple of centerboard boats at 28'. I am still a little concerned
about the stability. I'll have to give it some thought.

I think is is a fine idea. Is it the most efficient shape for the new
low-power boat mission? No. Is is cost effective? Absolutely.

$150,000 - probably more. An old 28 - 30' sailboat with clapped out sails
and a non-working engine could be found for a few thousand dollars. I have
a friend who just bought a nice sailable 32'er at a bank reposession
auction for $1000.

its is designed to have the ballast inside the hull, not hanging down 3'
below the boat. It will have much less draft than the keel boat, too.
