SOLAS Propeller Basics

  • 3 or 4 Blades: A 3 blade propeller usually offers top speed performance while a 4-blade propeller provides maximum thrust and smooth cruising operation.
  • DIAMETER: Propeller diameter is the distance across a circle encompassing all of the propeller blades.
  • PROPELLER Pitch: Pitch is the theorectical distance a propeller will move through the water for each revolution (i.e. a 21" pitch propeller should move a boat forward 21" for each revolution, assuming there is no slippage)
  • RIGHT HAND or LEFT HAND ROTATION: In most cases, right hand propellers are used for single engine applications and one left hand propellers are used for twin engine applications to achieve better steering control.
  • CUPPED BLADES: This is a technique used to enhance the performance of propellers under certain conditions. A cupped propeller will exhibit very high efficiency at high speeds as well as minimize cavitation under heavy loads.
  • RAKE: Rake is a special design feature. Positive rake benefits from normal bow lift to permit the use of a larger diameter propeller, while negative rake can provide extra blade strength for use in very high speed application.
