Autonomous Buoy

On the agenda for this session: DF95s and IOMs on a course with 3 autonomous buoys in a good breeze — 15 to 20 knots of wind and a nice swell. 🎯 Session objective To validate the behavior of autonomous buoys in conditions of sustained wind and real swell. Do they stay in position? Do they respond correctly to the conditions? That's what we wanted to verify visually that day. 📡 Embedded technology A GPS was installed on two DF95s (one with an A rig and one with a B rig) to p

During our regatta on April 12, 2026, we deployed a complete course consisting of 6 autonomous GPS buoys on the waters of Choisy-le-Roi. No more cumbersome logistics or safety boat trips to anchor or adjust the course: everything was controlled remotely, simply from a smartphone. During more than 6.5 hours of sailing, we were able to adjust the buoy positions according to wind variations, ensuring a well-oriented course for the race. At the end of the day, the buoys still had

A modular platform perfectly suited to marine projects Autonomous GPS buoys require robust, compact hardware capable of reliable operation in demanding environments. M5Stack modules emerged as the ideal solution thanks to their modular architecture, which allows for the rapid assembly of a complete system without complex soldering or fragile electronics. Key strengths: Compact and robust format , ideal for integration into a waterproof buoy. Stackable modules , allowing the a

We have just finalized a joystick for piloting and moving the buoys. Until now, the buoys and the Course were piloted exclusively with a mobile phone and an integrated dashboard. This is very comprehensive and practical, with advanced features such as one-click course setup and repositioning, and buoy visualization on a map. However, this dashboard requires all buoys to be connected to the internet. Therefore, we developed a joystick that can operate in two ways: In addition

Find all the photos from the Class M regatta on 16/11/2025 at the CNCR, in Choisy Le Roy. We used three autonomous GPS buoys, two for the starting line and one as a leeward gate. They performed well, except for one whose computer shut down in the early afternoon, after several stable hours. Analysis of the problem to follow.

Click on the photo below to see all the photos of the Class M regatta from 08/03/2026 at CNCR, in Choisy Le Roy, with about ten racers. We used four autonomous GPS buoys, two for the starting line and two as leeward gates. They performed very well and remained on the water, very stable, from 9:30 am to 5:00 pm. On average, 40% of the batteries remained after 7.5 hours of use in light winds. Cliquez sur la photo pour accéder à toutes les photos de la régate A video of the rega

Beautiful day for regatta racing, with mild temperatures but unfortunately little wind. A few pleasant breezes allowed us to complete 8 races. We used 4 autonomous GPS buoys to mark the course and reposition it according to the wind's whims. The buoys performed very well, remaining on the water for 7 hours. Enjoy the video summary below.

Discover how quick and easy it is to set up a complete regatta course using autonomous GPS buoys . We are very pleased to have achieved this goal. These new generation buoys allow you to deploy, modify and manage a course in record time — with unparalleled precision and without using an anchor. If you are passionate about RC sailing, autonomous systems or innovative tools for regatta management, watch this video!

Why Autonomous Buoys? Make organizing regattas easier : position up to 6 buoys in just a few moments, effortlessly. Adapt the course to real conditions : define your regatta according to the wind and the body of water. Gain autonomy : the buoys move and position themselves on their own to mark the route. Parcours type de régate VRC Why did you create these buoys? Traditional buoys require a boat to be launched, with the risk of damaging the seabed from the anchor. Setting up
