A new perspective on sailing

Trimming by feel?
Now see the forces.

You can feel the wind and the pull of the sheets. But how do you know what your sails are actually doing?

Feel

Experience the wind, the motion of the boat, and the behavior of your sails — the way sailors always have.

Measure

SailGauge sensors reveal the forces on your sails that were previously difficult to see.

Understand

Measurements become clear feedback, so you can make better-informed adjustments.

Wind instruments tell you about the air. SailGauge measures forces in the sail-control lines, helping you understand how your trim changes the loads on your sails. More information, without taking away the feel of sailing.

Development & testing

Taking the time to prove it on the water.

SailGauge is engineering-driven: bench and lab tested, and tested on the water. We believe sailors should see the work behind the technology — not just the finished claims.
