Technology should simplify, not complicate
One of the main concerns for anyone adopting new technology aboard a boat is practicality. Does adding sophisticated instruments really mean having to deal with complex installations, permanent wiring and modifications to the hull or the sails? With SailSensor the answer is no. The system was designed from the outset with a clear objective: ease of use as the absolute priority, without ever compromising on the quality of the data gathered.
Whether you are preparing for a race or heading out for a training session, the last thing you need is to waste time with awkward mounting procedures. SailSensor fits in a matter of minutes, works straight away and is removed just as easily.
A single kit for all your sails
Unlike solutions that require dedicated sensors for each sail, SailSensor takes a different and far smarter approach: a single kit can be used on multiple sails. There is no need to buy one set of sensors for the mainsail, one for the genoa and one for the spinnaker.
When you change sail, you simply move the sensors from the previous sail to the new one. Magnetic mounting makes this a quick and natural operation. The result? An affordable and versatile system that adapts to the way you sail and to your sail inventory without multiplying costs.
This design choice comes from real on-the-water experience: anyone who sails knows that sails are swapped constantly according to the weather conditions, and the system has to adapt as quickly as the wind changes.
Magnetic mounting: no holes, no glue
The heart of SailSensor's practicality lies in its innovative magnetic mounting system. The sensors require no holes, no glue, no screws and no permanent modification to the sail. The principle is as simple as it is effective: each measurement point consists of a pair of opposing sensors, positioned one on each side of the sail.
The magnets built into the sensors hold them firmly in place through the fabric of the sail, locking onto one another from opposite sides. No tools are needed, no adhesives are needed, no work on the fabric is needed. The sail remains perfectly intact.
This is a key differentiator compared with other solutions on the market: SailSensor respects your sail and lets you instrument it without any structural compromise.
Pairs of opposing sensors: the secret of the measurement
The configuration of pairs of opposing sensors is not merely a mounting choice; it is the foundation of SailSensor's measurement principle. By placing one sensor on each side of the sail — one on the windward side and one on the leeward side — the system is able to detect the pressure differential between the two faces of the fabric.
This pressure difference is precisely the fundamental aerodynamic information: it is what generates the sail's lift, what determines whether the trim is optimal or whether there is room for improvement. With SailSensor, for the first time, this physical quantity becomes visible and measurable in real time.
The pair of opposing sensors directly measures the pressure differential across the sail surface. This is not an estimate or a theoretical model, but a real reading of the distribution of aerodynamic forces on the sail.
Removal in a matter of seconds
Just like fitting, removing the sensors is immediate. You simply separate the magnetic pairs and the sensors come off the sail without leaving any mark. No tools of any kind are required.
This characteristic offers concrete advantages in everyday life on board:
Sensor protection — You can remove them at the end of an outing and store them safely, protecting them from prolonged exposure to sun, salt and the elements while the boat is laid up.
Total flexibility — You can move them between different sails depending on the sailing conditions or the discipline (cruising, racing, training).
Simplified maintenance — The sensors are always accessible for cleaning, inspection and charging.
No tool required. Separate the magnets, put the sensors away, and your sail is exactly as it was before. Zero marks, zero residue, zero compromise.
From kit to sailing: setup in 4 steps
From the box to real-time data, the journey is very short. Here is how SailSensor setup works:
Position the sensors
Place the sensor pairs on the points of the sail you want to monitor. The magnets attach automatically through the fabric.
Switch on the system
Activate the sensors with a simple tap. The data-collection module starts up and begins communicating with each pair.
Connect the app
Open the SailSensor app on your device and pair the kit. Pairing is automatic and takes just a few seconds.
Sail with the data
You are ready. View the pressure distribution across your sails in real time and optimise the trim.
The whole process takes just a few minutes, even the first time. From the second time onwards it becomes a natural gesture, as quick as putting on your lifejacket.
Designed for people who really sail
SailSensor was not born in a laboratory far from the sea, but from the direct experience of those who live sailing every day. The system was designed by sailors for sailors, and every single design choice reflects the real needs of those on the water.
The compact dimensions of the sensors do not interfere with the shape of the sail and create no additional aerodynamic drag. The app interface has been designed to be readable with the sun in your face, with wet hands, with spray coming in sideways. The battery life covers a full day of sailing without a second thought.
Every detail has been conceived for a single objective: to give you useful information without taking even a second away from your sailing. Because the best technology is the kind you do not notice using.
