Vee Gull Notes
VEE GULL SPEED CHART
The speeds listed below are approximate and not guaranteed.
They are based on the listed displacement and may vary if
displacement (weight) varies. All speeds assume wellfaired
hulls driving through properly sized propellers with suitable
gearing to match the power and torque curves of the engine in
question. All speeds are in knots per hour. To convert to
miles per hour, divide by .87. Horsepower is given as
constant 24hour rated SHAFT HORSEPOWER (SHP); NOT brake
horsepower (BHP), nor intermittent ratings. If only BHP is
known, multiply this figure by .70 for approximate constant
SHP. Figures assume S.A.E. methods. If ratings given in
D.I.N., these will be about 8% less than S.A.E. If ratings
given in KW, this will give ratings about 75% of BHP (S.A.E.)
ratings. In all cases, it makes no difference if the engine
is diesel or gasoline powered.
