How It Works

Sailing Simplified... by a simple system.

What’s Included in Your SailGauge Kit - SailGauge transducers, Display, and Master Module which is connected to the boats existing wind instruments.   Although simple, the power of the system is its ability to scales to include mobile device connectivity, autopilot control, and enables future autonomous operation.

How SailGauge works

The patented system starts with a SailGauge transducer at the base of the sheet block of each sail.   The sensors measure and calculate the forces and has no moving parts to fail.

The transducer can be scaled from 20ft to 2000ft boats.

Installation is straightforward

The SailGauge transducer mounts in the place of the padeye for the sheet blocks of either the foresails or main sail.    No modification of the rigging is necessary.   For the mainsail, the sensor can be mounted to the traveler or separately to the deck routing block.

Setup only requires distance measurements of the location of each sensor with respect to the jib furler or mast.

1. Mount sensors at sail sheet blocks (no standing rig modifications).
2. Input sensor dimensions relative to mast and furlers.
3. Input dimensions of sails
4. Connect sensors and master controller to display and wind instruments via your boats existing network. 
5. Power up and let SailGauge start learning.

Sensors have no moving parts and measure forces and angles. Sensors can be scaled for boats 20 to 2000ft in size

Sensor data and measured dimensions of boat features are used to calculate forces real time


Next comes a crazy bunch of math

Using real‑time force and angle measurements, our software computes optimal trim settings and adapts continuously to wind and course changes.

Vector calculations setup the 3D forces for use in the sail aerodynamic lift calculations.

Knowing the angles and vectored force, the driving forward force and lateral force are calculated


SailGauge learns the best trim

Once the aerodynamic lift is known... the patented system actually starts learning what trim is the best for each point of sail.

By knowing what is best, it can now provide assistance to the sailor and provides a path for future autonomous operation of the boat.

Relax... Your boat already knows how to sail.

SailGauge knows the positions and status of the sails and the best way to trim them.  Once installed, it calculates trim adjustments and delivers clear instructions—via display or mobile app—when it matters.
