Yes, It is akin to flying an airplane consistently 2 feet above a runway covered with 1 foot high bumps and potholes, inside a shed with a roof...
Hello Andy, I think it is very good that you try all ideas and find out your own results. On the weekend I tried 8 different configurations...
RVELL, Thanks very much for your contribution! I agree completely that this may work OK, and that you can take off by adjusting the lift of...
It is of course possible to lift off with a fat stern by putting a positive angle of attack on the main foil. You can do this by simply raking it...
Phil, Some big decisions to be made if you are building a new boat. Looks like you have given up the bow rudder idea altogether. I think you...
Phil, If I continue this calculation.... In order to keep the boat balanced and sailing level when hit by a gust, without moving my body weight,...
I think Tom has made a key contribution here and has been prepared to admit his prior error....it seems we have now all been through this stage!!...
Hello Ray, It is very good of you to take the time to respond in this forum, I think this is a really crucial discussion as longitudinal...
RVELL, I am interested to know how actual loadings change on both main foil and canard when a forward pitching moment is applied. I am...
Hello Doug, Two foils is of course ideal as all boats need a rudder and centreboard anyway. John Ilett has done a fantastic job getting the two...
Here is a photo of my swing rig for a Moth being used in current Moth foiler testing. It uses a 2Kg carbon mast from Furya in Japan, extended to...
Pretty simple really, to keep the bow up, the canard always provides positive lift, which is assists the main foil by unloading it. If we were to...
I do not see why the canard must carry more load per unit area than the main foil. In normal running mode it has little or no load. As it pitches...
RVELL, The short answer is NO! The dynamic stability of the foils provides much better stability than when simply displacement sailing in what...
Dinghy foiler height control and longitudinal stability The biggest question with Dinghy Foiler design right now is how to manage both height...
Andy, This is the same logic I was using and is how the Miller sailboard works. The two main problems I found were: a) The foil at 40 degrees is...
Scow foiler I have been working for some time now using a non-winged Scow as the platform for trials. Appart from being simple, easy to rig and...
Stevo Bow Foiler Here are some photos of Phil Stevo's latest foiler with a bow rudder... Some very good engineering here and important lessons...
RVELL, Thanks for your good contribution. This is a very useful innovation and may help solve several problems.! On the monofoiler dinghy, I...
