Is this your idea of not doing much??? [ATTACH]
[ATTACH] This is the book. My Dad was inspired to build something similar when I was a teenager. It was amazingly fast in spurts, but tricky to...
The Mini40 RC class has some successful foilers to compare with. If you're on Facebook, there's this group: Mini 40 Multihull | Facebook If not,...
When I wrote that, I meant the boat's wetted-surface area, but I should have referred to its overall drag instead. I hate being too negative, but...
Is this the boat you're referring to? [ATTACH]
Sorry, but I don't think this is very promising. Compared to a Moth: Your boat is a lot heavier, with more wetted-surface area, and a fraction...
If you say that it's your opinion that having a better section shape wouldn't make much difference, then I wouldn't argue with you. But you can't...
I think the answer is that you could probably get away with this in a lot of existing boats, but you would lose the efficiency & steadiness that...
But you need the foil to be on the opposite side of the hull from the kite to keep it stable. If you tack the sail without the foil, you'll lose...
Wouldn't the worst case have the load concentrated at the center, instead of uniformly distributed?
Why were you doing that?
I could have sworn I had an article about sailing B-Lions, but I haven't been able to find it so far. I think it was one of Bob Smith's series of...
Do you really need to have two of them? Sabots seem to do just fine with only one. (It's symmetrical, of course.)
Without thinking too much about it, it looks to me that (Blue = Catamaran) & (Red = Trimaran).
Great explanation Tom. You should write a book!
A few comments for the uninitiated: "Recovery" typically refers to the increase in pressure on a foil aft of its minimum value, as it approaches...
On a similar note: Foil drag can be reduced considerably by inducing ventilation. You may not be pleased with some of the side-effects though :)
It's possible for a turbulent flow to separate and then reattach, thus forming a "turbulent separation bubble." This could be caused by a local...
I've got absolutely no clue what you're saying. But, nevermind, I did some more digging into family history and it looks like he built the boat...
Sure. Those photos I posted are all Moths (11' long). But I don't see anything wrong with larger ones (the ones with higher freeboard anyway)....
