Thank you for your interest in my Skoota powercats
So far I have designed a Skoota 20, 24, 28 and 36. Several 20's and 24's
have been launched. Two 36's are building. A 32 is on the "drawing board",
actually "screen" of course. I don't have any plans to draw any larger
powercats
The 20 and 24 are true trailable boats. The 28 is "transportable", so is
something you might do once a year, maybe when taking it to another
cruising ground, as we plan to do, as I mentioned in my last post.
So you can take it apart for transporting by road but sensibly it will
require boatyard help to assemble. Each hull is under 4ft wide, so the two
go together and are under 8ft total. The cuddy is 12ft by 9ft10in x 6ft2in.
So, if you can transport it at under 10ft width, it all easily goes on one
flat bed trailer, 28ft + 12ft = 40ft. If you want to keep it under 8ft wide
then the cuddy can travel on its aft bulkhead, so it is 6ft 2in wide but
10ft high. On a flat bed trailer you'll still be low enough to get under
bridges etc. The cockpit panels, anchor lockers bolt in place and sit on
the hull tops for transport.
If you look at the build photos you can see that the hulls were built in
the builders basement, (check the videos of moving them and turning them
over). However it was completed in a small shed in Sequim, Wa. This shed
had a 10ft wide door. So after building the boat we disassembled it and
took it outside in pieces (all by man/woman power). Then the two hulls were
loaded on a flat bed trailer and pulled by a friends pickup 40 miles to
Port Townsend.
There the hulls were again man/woman handled off the trailer and set up
ready for the cuddy and cockpit. That was on a Thursday, in the snow. On
the Tuesday the weather improved and we used a flatbed truck to deliver the
cuddy. We could have fitted the cuddy ourselves, but when we arrived at the
boatyard the crane driver said "its my lunch break, I'll drop it in place
if I can do it in 10 minutes" which he did. We had left Sequim at 11.30am
and by 1pm the boat was fully assembled and could have been launched
(except we still had to connect up the engines). Instead it was launched on
the Thursday.
The empty weight of the complete boat is about 1.6T, or say 3600lbs.
Floating on its WL it is 2.3T, say 5100lbs. The antifouling line (actually
Coppercoat - which works very well in the PNW) you see in the
pictures/videos is 40mm (11/2in) above the 2.3T mark, so even while
cruising to Desolation Sound we were lighter than 2.3T
The engines are actually twin 20hp, which gives 16 knots WOT. The max I
recommend is twin 60hp to give speeds in the mid 20's. We cruise at 10-12
knots and do 5-7mpg. The engines are too small to use fuel flow meters. But
the consumption figures are accurate. That's because last summer we were
using the 3gal fuel tanks that came with the engines. So I had to refill
them every couple of hours.
A trip from Vancouver to Saturna was typical. We motored 38 miles in 3 hrs
20 minutes, so averaged over 11 knots, and used just 5gal of fuel (over
7mpg). When I got back to Saturna I refilled those tanks with a 5gal can
and still had a bit left over. We now have our "big" 17 gal tanks installed
which should give us a range of about 200 miles.
The 20, 24 and 28 Skootas all use asymmetric hulls. The 32 and 36 use
symmetric hulls for better load carrying and because they will be more
offshore rather than inshore boats. The narrow, asymmetric hulls are wetter
in bigger waves - but work well in the Georgia Strait, Inside Passage or
ICW of course. We motored about 1000 miles last year with no problems.
Our boat was built by Josh Turner of Wheelhouse Woodworks. He did a great
job, very fast, very careful, very accurate. Highly recommended. We paid
him for 2300 hours, but we painted the boat, which is why it doesn't look
that good close up. I don't (want to) know what the materials cost was.
Guessing about USD30,000 as you see it. Josh says he can build another one
for about USD120,000 for labor and materials, ex engines
I hope that answers your questions. If you have more maybe you should email
me direct rather than have me answer on the mailing list. Your choice

Thanks, Richard, for the detailed response on Skoota.
I hope you will continue to answer such questions on the List rather than by private email. We only learn when we share.
