If the waterline length is 20 feet, what is the maximum safe speed of a sailboat? Answer by solver91311(18785)   (Show Source): You can put this solution on YOUR website! No. The hull speed of a sailboat is 1.3 times the square root of the waterline length. (actually, 1.34 is a better approximation, but who's counting). So you want: All you have to do is substitute 20 in place of the and do the arithmetic. John My calculator said it, I believe it, that settles it
