Propeller Calc vs One Touch Tow Lite

This calculator can determine pitch, gear ratio, RPM, propeller slip and speed parameters. Enter any four variables, and it will calculate the fifth. Use the toggle switch to choose which field to calculate. Pitch is the theoretical forward movement for one complete turn of the propeller. Every inch of the boat in contact with the water induces drag. Therefore, the distance travelled differs since the propeller is "slipping" behind the theoretical distance it should travel with each rotation. The difference between theory and reality is called slip. Depending on your application, slip typically ranges between 5% and 20%. A lower number is only sometimes what you are after. Slip of a prop changes with operating conditions and is not a direct measure of efficiency. Please consult professionals for guidance. Happy powerboating

The One Touch Tow Lite is a tire monitoring system for your trailer. The system monitors the trailer’s tire temperatures and tire pressures. This data is collected from the sensors provided when the One Touch Tow system is purchased. The tire sensors can be retrofitted onto nearly any trailer, truck, or RV. This application has a list page, showcasing all of the user’s trailers, a trailer page, which displays the trailer’s data (tire pressure & tire temperature). The app also has a setting page, allowing users to update tire sensors and change the thresholds of the tire pressures and temperatures.
