A unit of speed equal to one nautical mile per hour (1.852 km/h or 1.151 mph). The standard speed measurement in watersports and marine navigation.
Knots originated from the old practice of throwing a knotted rope overboard to measure a ship's speed. Today, knots are the standard unit for wind speed and boat speed worldwide. When a weather forecast says "15 knots," that's about 28 km/h or 17 mph.
Most watersports apps and GPS devices display speed in knots, km/h, or mph. For quick mental math: multiply knots by 1.85 to get km/h, or by 1.15 to get mph. Wind speed in knots is what determines your gear choices — a kitesurfer might use a 12m kite in 15 knots but switch to a 9m in 22 knots.
Watersports Tracker records your speed in your preferred unit and shows max speed, average speed, and speed over each section of your route.
Example usage
"Wind was 22 knots today — perfect for my 9m kite. My GPS showed a max speed of 31 knots on a broad reach."
Watersports Tracker records your speed, distance, route, and more — for 24+ sports.
