the boat recently towed it on a trip to some islands off Key West got caught in
some bad thunderstorms the dink was jumping clear of the water on some waves
towed like a charm left the plug out stayed empty even in the storms had a good
time once we got there. Have a good day.

Hi John
Recently finished the boat I built
from your plans. It works great and is pretty. You
should be getting some pictures in a few days. Any questions should
be emailed here hardymarine@earthlink.net
Its a new ISP from
the one I had when I ordered the plans. Love the boat! Planes
in a good chop and is dry, sails well, makes 22 miles an hour with a 15 HP
Mercury, is self bailing and unsinkable as it
is made of foam. Thanks again. Have
a good day!
