[Rhodes22-list] Measured Hull Speed

[Ronald Lipton]

Hull speed is not an absolute limit - it is just the point where the power
vs speed curve becomes very steep.   To do a proper job one should
plot speed vs engine RPMs and see where there is a significant change
in the slope (I have neve seen cush a plot myself).
