My lifting foils and strut foils are canted forward to reduce the effect of ventilation. Bill Roberts has often raked boards forwards on big cats, it seems. NOTE: If foils are raked back, introduced air is quickly propagated down the foil onto the lifting area...which is not what you want.
Hollis Caffee told me today at the Gulf Coast A-class Championships said he may run his Rave in the Miami-Key Largo race again this year..last time there was lots of weed in Biscayne Bay from an east wind....which foilers do not want either!
PS: Woody Cope snaked away another big win. Way to Do, ButWheat!
