MarkSetBot improves the quality and sustainability of racing, makes it possible to run more races in less time and results in happy racers and race committees.

"[MarkSetBot] has added a lot of quality to the racing. We don’t need to wait when we have a big wind shift as the marks can now be moved very efficiently, which ensures the competitors aren’t waiting a long time for the racing. Sometimes when the water is very deep, the mark layers need a lot of time to reset the course but with the robotic marks, it can be done very quickly. This makes it easier to get a higher degree of accuracy, and so the quality of the racing is much higher."

Maria Torrijo, Principal Race Officer, RC44 Cup

“The robotic racing marks from MarkSetBot proved their worth from the outset, not only protecting the seabed as part of ClubSwan Racing’s commitment to sustainability but also able to be easily repositioned to take account of windshifts.”

The Nations League Swan One Design

“I’m amazed at how accurate the MarkSetBots are. I noticed it when I was pinging the line. Every ping, they were in the same exact place. In shifty venues, you’re able to make course adjustments so easily by just pressing a button. It was very efficient and I think we were able to run races in conditions that otherwise would have been a lot more challenging and maybe not possible.”

Victor Diaz De Leon, Professional Sailor

“I recently did a Club-Swan 50 event and they used really cool self-propelled, no anchor GPS-controlled race marks – they were working in current and good breeze and waves and it made for simple racecourse adjustments and far fewer people needed to run the races.  If you are a starting-line perfectionist PRO this gives you free reign to move the mark up to about five minutes before the start and still allow people to ping the pin.

Fewer people.  Fewer anchor lines.  Fewer boats needed.  Less fuel.”

Ken Read, President, North Sails
