This looks reasonable. Unlike the normal, vertical sails, kites produce much smaller heeling moment, so the lee hull is not heavily loaded (nor...
You may be right... or not. This layout is so uncommon, that little is known about its hydrodynamics in practice. Traditiona Coble works, as well...
I meant the leeway with respect to the centerline. When heeled, the immersed hull is rotated by a few degrees, plus some helm to balance the boat....
My crude idea about Coble looks like this: [ATTACH][ATTACH] [ATTACH] Hull length 4m, width 1.6m, hull draught 0.32m, 0.9m with rudder....
Coble is a very unusual boat, which "futuristic" solutions fascinated me for years. She doesn't have any centerboard nor protruding keel. All the...
This idea is sometimes used in Moth dinghies, especially for training [ATTACH] regards krzys
2.25m pram, lapstrake plywood construction
Our family boat. 5.5m Miś, traditional plywood construction, designed by Zbigniew Milewski in 1970, built by Władysław Michalski in 1975, still...
4.5m proa built of extruded PVC plates in one day, during a festival in Bydgoszcz. Then sailed for two years on Jamno lake, destroyed by a storm...
5m Pacific proa built during a festival in Szczecin in two days (plus two weeks of preparation). Sailed along Baltic coast for several years.
5m cuddy sailboat made of tortured ply
Not in this layout, where wings are also the float struts... krzys
Long floats, working as tail booms. So, the same potential issue with too much pitch stability. I agree that S.65 looks awkward, especially in...
Your long floats seem to allow for the increase of angle of attack by about 3deg only. You will need very efficient flaps to take off. Compare...
Apparently not. Piaggio P.7 hadn't one Piaggio P.7 - Wikipedia https://en.wikipedia.org/wiki/Piaggio_P.7 regards krzys
