I've been thinking about this some more and believe from the dinghy aspect the hull may actually be a low drag efficient planing hull. A lot of...
Hi Thanks for your input. I have started to survey whats worked and find for example there are 3 lasers smallest sail is 4.7m2 I have I think...
Fenced V foil sail inflatable. Plan B. Following some helpful comments from the forum conclude that the V foil proposal whilst relatively simple...
OK thanks for the honest advice. I might still have a go if only the new sail set up works OK will give me some satisfaction not to many...
Doug did you mean wetted-surface are of boat or foils ? I thought you meant boat but could see that the v foils compared to a laser radial pylon...
Hi yes. The Optimus rig is I think 3.3m2 Since this picture increased rig with a sail from a windsurfer of around 5.5m2 and a lot higher mast of...
Hi thanks for your efforts. So are your conclusions would need 32 knot wind speed for 150lbs thrust with 5.5m2 sail rather than 15kn? in which...
I figured that a heel to port for example the projected area of port foil would increase giving increased lift and at moment of heel added angle...
Thanks for that. So I think idea might be feasible just. Assuming take off the AC75s seem to get faster speed than wind speed due to higher...
Hi thanks for your input. The hull is a planing hull and I think with my 4hp outboard would do around 7 knots guessing 150 lbs thrust. Believe...
Looking in a bit more detail at Radial laser 5.76m2 sail and 60kg hull. Inflatable is 50kg plus mods plus rig around 65kg plus me allowed 150kg....
Hi thanks you could be correct one reason I wanted to make construction simple as possible. I think the moth can do 15 knots plus and has 50% more...
Inspired by the AC75 racing I am toying with the idea of fitting foils to my Caspian inflatable I converted to sail with an Optimus sail rig...
Hi I have made about 20 moulds for GRP including a twin skin sea sled dinghy, Cruiser aft cabin, cockpit mouldings and cockpit roof . I have used...
