Abstract
The sail force gauge utilizes an electronic system to measure the vectored force of the mainsheet or jib sheet. By gaining the vectored force of the sheet, a relative vectored force upon the sail can be acquired thru simple trigonometric equations. To obtain the vectored force measurement, a multi-axis load cell will measure the force in the lateral and axial directions. These forces can be used to calculate the vectored force of the mainsheet. By knowing the dimensions of the boom length, the sheet block positions, and the vector angle, the resultant angle of the boom can be calculated as well as the perpendicular sail force acting upon the boom. From these calculations, the relative axial force acting upon the boat can be calculated.
