MARINE propellers are designed to provide the
maximum thrust and the minimum torque for the
optimum propeller rotation speed and the required cruising
ship speed which allows ships to efficiently travel at their
design speed. However, it is important to know how the
marine propeller performs during off-design situations as well
as deign point by knowing its open water performance. This
is important for all naval marine propellers whose missions
require them to perform at a wide range of speeds.
Choosing the correct marine propeller is a vital
