Default RE: RC multihulls?

HA ! I thought you would like the size. !

Yes, it would be a problem to transport - but my goodness, set up with minitaure Harken winches, travellers and blocks, along with static (non-working) bits and pieces you must admit it would be a wonderful sight.


Here is a photo of a rudder foil on a scaled down 1 Meter US boat (State of Washington) built from the Mini40/F-48 plans obtained from Mike Friend (a fellow UK multihull enthusiast) It is "PULSE" and I believe it was UK Championship in late 1990's as I recall. You can see that there isn't a need for huge foils, just enough to start downward pressure as water flow moves over the foil. At slow speeds, (light wind) you don't need the foil, so very little negative angle is required. As wind picks up, boat speeds up and more water/pressure takes place to begin to try to force the stern down and keep bows up.

In my old 1 Meter, I had a small foil that had only 1 degree negative angle. Some will use up to -3 degrees. Hope this helps.
