Sail Area Calculator
Introduction
Calculating sail area is crucial for sailors and boat enthusiasts alike, as it determines the power and efficiency of a sailboat. With the help of a sail area calculator, you can accurately estimate the surface area of sails, aiding in performance optimization and safety on the water.
How to Use
To utilize the sail area calculator, input the necessary measurements of your sailboat’s sails into the designated fields. Once you’ve entered the required information, click the “Calculate” button to obtain the precise sail area measurement.
Formula
The formula for calculating sail area varies depending on the type of sail. However, for a standard triangular sail, the formula is:

Where:
- BaseBase represents the length of the base of the triangle (usually the boom’s length).
- HeightHeight refers to the vertical height from the base to the top of the sail.
Example Solve
Let’s consider a sailboat with a triangular mainsail. The base (boom’s length) measures 10 meters, and the height from the boom to the masthead is 12 meters.
