Video is at half speed, hopefully showing speed and sailing characteristics of design. New leefoil for free sailing model achieving better balance. Along with a better adjusted sail . Model is sailing to windward, winds 10 to 14 mph with some stronger puffs with out dagger boards or fixed rudder. leefoil proa
Look at the direction of the water ripples caused from the wind and when the sail stalls to get an idea on how high the proa is pointing. Also watch foil in the steadier puffs .Boat heels foil sink to a depth rises as it reaches speed stabilizes .Once stable the gust just excellerate the boat foward with out heeling. lee foil proa...
