A prop slip calculator is a tool used to estimate the amount of “slip” or loss of efficiency in a propeller. Slip is the difference between the theoretical speed of the propeller and the actual speed at which it moves through the water. It is typically expressed as a percentage, with a higher percentage indicating greater slip. Many factors can affect propeller slip, including the shape of the propeller blades, the pitch of the propeller, and the speed of the boat.
Propeller slip is important because it can affect the performance of the boat. A propeller with excessive slip will not be able to move the boat as efficiently as a propeller with less slip. This can result in reduced speed, increased fuel consumption, and decreased maneuverability. Propeller slip calculators can be used to help boaters select the right propeller for their boat and operating conditions.
