Peter, "Beyond this speed the vessel tends to squat (trims down by the stern)" "More lifted => more planing."
If you aren't careful you will end up agreeing with me on the definition of a displacement hull.
"Regarding the actual power required for a round bottomed proa travelling at speeds considerably above 1.34 root LWL, I suggest you accept Rick’s calculations, he has quite a lot of experience with easily driven hulls of this type."
I am not interested in the power requirements for a round bottomed displacement hull. I am interested in the power requirements of a FLAT bottomed fast displacement hull, like the HP, that does not squat.
Should I assume that you are unable to provide accurate numbers?
Sincerely,
Talador
