JimB I am sure it will be possible to build variable area foils either by extending the section width, swing wings etc. You are certainly on the...
As reported in other sections of this forum: Dihedral provides very good initial stability and tends to rolls the boat in to windward....
Fully pivoting foils I agree with Jim B completely! There are several people in Australia and Germany currently developing solutions with the...
Alan, John Ilet commented in Melbourne that at high incidence angles the flap was in fact fully up and the boat was still lifting. You see this...
Incidence vs flaps A question for Tom Speer. At take off, with relatively low speeds, if you have a choice between increasing incidence of the...
Phil, Any thoughts on why you are not yet getting better performance than displacement hulls yet? What about on reaches?
Hello Doug, In principle you are quite correct! What I notice in practice is that it does not take much windward heel to get a big effect. You...
