Thankyou all for your prompt and very informative responses to my questions.
I have received the following response from Matt McDonald, at Vectorworks Marine, which some may find of interest.
We will await futher announcements for the next batch of boats.

Jim,

To answer your questions; Phill Brander designed this platform, and we have
signed an agreement with him to produce this design in composite here in the
US. We have constructed new molds to his specifications and have done the
laminate design to make this in composite. We will be selling complete
boats as well as components for the home builder as we have demand. We can
not sell molds as this would violate the copy write design from Phill. He
is selling plans, I believe now, to make a plywood home version.

The prototype is just being finished now, and a formal announcement of the
project will be coming out after its debut. This will include pricing and
the schedule of availability. Pricing will be competitive with the other
boats currently on the market similar in configuration.

There are a couple of guys from Tulsa that have been to our facility and
seen the work in process. There are also some really good reports coming
from everyone who has sailed the original wood prototype in Australia. This
should be a really great platform.

Thanks for your interest, and we will add your name to the list of people to
contact when this comes out if you wish.

Matt
