Adding Great Stuff will add weight to the boat. It will sink lower.
The only way to get more bouyancy is to increase the size of the hull - and...
Prepreg is about 30% resin.
Lots of technology and work to get there.
NO. That was exactly NOT my point.
The drive does not have to be the same as the whole boat.
You can easily have a submerged "fish drive"...
A propeller is not half immersed (most of them).
Any fish copying drive would be immersed (with rare exception).
If you want freedom of ideas,...
Then it should be easy.
When will you demonstrate your idea?
Seems like it could be cheap to demonstrate.
At least at the beginning.
Great videos and the best offer I've had in a long time.
I'll be interested in more heavy weather sailing video!
From your previous discussion, that's what I thought you'd want.
After thinking about this, I believe you would get more speed by filling in the gap between the hulls.
I don't know what to do to mount...
Your "power" idea is pretty neat.
Another thing the typical peddle boat has problems with is wave interference drag between the hulls.
Great, when's the launch? :)
This is just Ferrier's patented system from 30 years ago.
Nothing wrong with it, but nothing new either, from the very minimal information...
That's a pretty big request.
You only covered dingy design from about 100 years ago to yesterday.
Want to know about the best materials and...
Thanks, somehow I didn't pay attention to the heel to windward.
I assume there was either a lull or the helm brought the boat into the wind for a...
I think I understand the situation you describe, but I don't know what difference it makes to giving a benefit of any kind.
Are you saying a raft...
What do you mean by support?
Isn't that what displacement means in a multihull?
How is control affected?
He's saying that when you start sailing...
Did you mean "to have the Windward ama out of the water"?
I was just suggesting that Ama bows fwd of the Vaka bow is better than Ama bows well behind!
There were some daysailing tri's from Australia...
I really am looking forward to this boat.
The ama's need to be raised so all the hulls are not in the water at the same time.
Raise up the fwd...
Someone tell me what actually happened.
Looks like the skipper lost his grip on the tiller and too much weather helm caused the veer?????
PVC spacers are going to be a sure failure point.
Or have you calculated that also?
