Some more experiments along these lines:
I can't answer your question, but I have made and sailed a model cat with a wing jib:
And quite a few mast aft wings, which are a...
Your rotating rib approach for the wing is ingenious.
I'm impressed by the stability these foils provide. I cut down the width of the cat considerably, and it is still very stable:
I think that this might be right.
Doug L's point that this is something like the Quant Scowl arrangement is also interesting. It makes me...
Less windy conditions:
WRT RM, my comment was based on observation. The boat seemed to be much more upright than I would have expected with a more conventional...
rc cat with outward facing foils
I have been looking at this type of foil on rc cats. As predicted by others, altitude control is an issue....
Very nice Gary. How did the performance in the two configurations compare?
See from 13:30.
Thanks again for the detailed explanation. I like the two flap idea. It seems to me that there should be other ways to exploit the leeway other...
I may not have explained the flap position properly:
Thanks for the explanations. In summary, would it be correct to say that if we ignore heave stability control, the outward facing foils should be...
I understand this, and it makes sense if only the leeward foil is deployed. But what if the foils cannot be retracted and the windward foil is...
I've seen some threads devoted to this question, but I'd like to raise it again. What is the problem with outward facing foils on a cat? In...
Do you think I would get away with a windsurfer sail?
I've had a look, but it is a bit hard to tell if they sail at all well. You are right, it is pretty simple, I may as well just test it....
Thanks for the correction, I don't know what I was calculating. How about "reasonable" sailing performance, I'm not really after "great".

An addition to the crazy ideas for home made multi hulls. I'm thinking about trying to make a proa from two old...
