Hi Robert,
Yes, Rob, Michele and I were a good team for a long time but after five
years I feel I need to move on.
Designing catamarans is really quite easy as they've been developing
for a long time so a lot of it is now empirical. The challenge has
been to design in Polycore, a flat panel material, and making it look
good.
I've never been quite sure about the extra sailing loads argument as
the rigging loads on a cat are taken by strips of uni in the top and
bottom of the bulkheads, not a big deal. Also weight isn't necessarily
a big factor. Where a proa saves weight is in not having so much
material as they don't have such an extensive fitout, and not so much
solid bridgedeck and saloon. I think a proa built with the same
accommodation and appointment as a cat will weigh about the same. Where
a proa gets it's performance is in the extra waterline length. It's
pretty pointless comparing proas with cats as they are such different
beasts fulfilling different rolls.
The biggest downer in designing conventional cats is using a
conventional stayed rig. I'm missing free standing carbon masts
already.
Actually I'm still playing around with them as I have the contract to
build all the carbon masts for the Norwalk Islands Sharpies range
www.nisboats.

It is sad to hear but can understand. I thought the tension and
cooperation were a good and productive coordination, but not always
easy. It must be a little frustrating for Mark to have to design for
all those extra sailing loads and subsequent weight, but the regular
money and lack of dealing with sticky stuff would compensate.
I may be interested in helping on the website but am not sure if I
have the skills,
Robert
