Sailboat Speed Calculator

FAQs

How do you calculate the speed of a sailboat?

Sailboat speed is influenced by various factors, but one common way to estimate it is using the following formula:

Speed (in knots) = 1.34 * √(Sail Area in square feet) * √(Wind Speed in knots)

Please note that this is a simplified formula and actual sailboat speed can vary based on wind direction, hull design, sea conditions, and other factors.
