I got my first multi, a Corsair F-27 tri. I later upsized to an F-31 as
it was a much better boat in the Lake Michigan type of chop. I then
went to a Manta 40 of which I picked up at Saint Petersburg, Florida.
I along with my brother took the boat up the ICW, Chesapeak Bay,
Jersey coast, Hudson river, Erie canal, Lake Ontario, Welland canal,
Lake Erie, Lake Huron, Lake Michigan down to Racine, Wisconsin
for the on the water boat show. A trip one day short of seven weeks.
One great thing about multi sailing or power is that you can travel
when most mono hulls are tied to the dock.

After having too many sailing days in pain from old sport injuries, I
decided to go power multi. I now have an as yet to be finished Trawler
style cat that I ordered as a 48 foot but through the build process it
got stretched to a 53.5 with swim step. After launch and 19 inches
down in the bow, the builder kept heming and hawing about how to
fix the problem. I finally got disgusted, called my marine surveyor
and we got a marine engineer who had cat experience and is a
hydrodynamist. With a new larger better shaped bulb and a total
re-make of the after section, the boat sits level, the transom is the
end of the hull. The boat as proven in the last sea trial done in 25
Knot breezes with 30 Knot gusts and short duration chop of 4 to 6
feet is very stable and the new hull slides through the water. All the
wake is created from the after section. The down side now is the low
horsepower engines versus too much weight giving a top speed of 11.5
Knots full speed in flat or choppy water. The swim step is now on top
of the hull where it should have been in the first place. In a 2 to 3 foot
chop I have stood on the swim step at 11.5 Knots without getting a
drop of water on me as I looked the tunnel to watch the water flow.
This boat is now a true 55 feet. Not fast but very stable. Because of
the weight, the boat is now a displacement type.

I learned to canoe and sail in wooden sail boats at age 8. I got
interested in multis when the Hobie cats arrived on the scene. My
F-27 was purchased in the mid eighties. I am now 70 so you can see why
I learned to sail in a wooden boat.


Thank you for sharing your experience with us, Stuart.

You're such a gentleman not to publicly name the designer or builder.
Those who really want to know can send you a private email.

What's the new boat called? Where will you be cruising this summer?
