I am open to discuss construction techniques and such in this forum.
I am curious about one thing - did you build this using cold mold
techniques?
Actually this boat is a traditional plank on frame construction. We did
incorporate a ply/ plank bottom to reduce maintanance issues. But other
than that it is built using traditional methods. I did improve on the deck
to hull construction. CC used the margin plank/beam and butted the side
frames and deck frames into that. I married the deck frames directly to the
side frames and treated the margin planks like planks. Much thinner and
lighter but still very strong. We used a gel epoxy throughout the boat
along with about 7000 silicon brone boat screws. While we did not have to
steam any of the planks or other components we did utilize very hot water
baths for 20 minutes for the more agressive bends.
By the way, anyone interested in buying one of these? G
I'm not that's for sure.
Although if you could transfer that drive technology to a 23' CC that
will do 30 mph on extended runs - like say for eight hours - I'd be
all over it. :)
Just for the record, we are using a 15000 watt battery pack that weighs 828
lbs. Add to that the battery cable, 2/0 welding cable, the charger, this is
a plug in, Controllers etc.
With battery technology what it is today we are lucky to push a nice little
light weight hull like ours as much as we can. The future however is
looking brighter for much better batteries with higher capacity and much
less weight. Still I would venture a guess that a 23' CC would probably
weigh 3500 4000 lbs? Our baby weighs in at a mere 2200 without passengers.
I used a monocoque construction which enabled me to use much smaller
scantlings through out the boat. She was designed for this application.
For your application if you want to go green, bio-diesel then you have a
real stink pot G
