For 30 years, CLS and Pen Duick have cooperated, equipping skippers with several generations of ARGOS beacons. To improve the safety of the skippers and provide organizers with real-time positioning services, CLS began to equip sailing vessels with March YI beacons: light, waterproof and shockproof, with autonomy of 110 days.
CLS provides satellite tracking beacons for 91 participants and uses advanced technologies to locate and track vessels. Using satellite-based systems operated by CLS, race organizers, the general public and families of skippers and explorers can monitor step-by-step the progress of modern-day heroes. For more than twenty years, CLS has equipped tens of thousands of navigators and explorers, both on solid ground and on the oceans.
