3.13 Useful Information

Boat Speed and Engine Efficiency
Speed depends on many variable factors and therefore no
catalog or advertised speed can be guaranteed. Some of the
factors affecting boat speed are presented below.
（1） Atmospheric Condition
Engines will develop more power when the ambient air
and water temperatures are cooled. Power variations due to
temperature can be as much as 10﹪and for this reason greater
speed are generally obtained in spring and autumn, rather than
in the summer.
（2） Personal Equipment and Accessories
All personal equipment, accessories and extra passengers
will tend to decrease the speed. Often the effect of this added
weight is not taken into consideration when the performance of
the boat.
