You published it in I believe 76, in
Multihulls Mag. I probably still have the copy in my
Multihulls Mag collection somewhere. It was a 31-32'
open deck cat with all accommendations in the hulls,
like Tennant's racer/cruisers only earlier. I called
you from the US which cost quite a lot back then.

Stealing is a strong word. He

It's close though, let's not get into sematics.
But like I said, it happens all the time, especially
in the boating world.
You could have at least mentioned my name as the
originator instead of making like it was just your
original idea was your only real obilgation.
My guess is I inspired you to bring plans out
since because of lead time on the mag, you would have
to have done it right away, within a couple weeks. And

It should be noted at the time. Multihulls were
a very, very small number, probably less that 5,000
western multihulls other than day cats. Almost
anything you did then was new.
I ended up building several like it to my
designs in tortured ply and in other sizes.
I looked at your website and didn't find it

Let's admit it, at the time you were one of the
better known designers so it was a compliment to be
worth 'copying' from.
It told me that I could design it by myself just
as well which turned out to be correct and worked out
much better as I got just what I wanted in the
materials I wanted. That allowed me to build really
good, fast, safe, light, heavy load carrying
multihulls for about the same price as the laughable
Wharram cats of the time.

Actually I used flat table, floor molds since
69 working for Wellcraft powerboat builders as one of
my first jobs here in Fla. And is common in the
boating industry before then as was cores.
Also Marina84 in Ft Laud Fla used a 80x20' flat
mold back then to build one off power yachts, later
ungraded to 120x20' when I worked there.

It was the complete design concept, set up,
not a single feature, to the T. We talked quite a

While I like flat tables, I like round bilge
for speed, lower drag, more pointy bottoms to cut
damage grounding so I moved on to tortured ply as it
took so little time, cash. And to sell boats you
needed both to make a profit. I do use them now to
make car parts, plugs, molds.

Not in the US. It was used here many yrs
earlier. Since you were about the first to build
multihulls in glass, maybe for them. The rest of us
were smart enough to build in wood on one offs!!!
Though FG cats definately sold better, wood/epoxy is
lighter, stronger, easier, lower cost.

The how was entirely my own work.

I'd be interested as I'm getting back into
composites building Electric vehicle body/chassis for
my soon to be in production EV.
I really don't have problems the way I do my
flat table layups but always interested in new
methods. A problem here is you don't have 30 minutes
for the resin to flow as it goes off in under 15
minutes in our Fla heat. I'll check to see if longer
time resins are available.
