BOAT SPEED CALCULATION

            Boat Speed ( knots ) = 0.6 x L / T

            where:

            L =  Waterline Length (ft)

            T = Time (sec) for something to pass along length of boat.

                    e.g. for 20 ft  waterline and 2 second;

                             k = 0.6 x L / T

                            k = ( 0.6 x 20) / 2 

                            k = 12 / 2 

                            k =  6 knots
