Eagle Notes
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.
