MarkSetBot: Intentionally Engineered for Better Race Management
Better Visibility. Better Control.
Better Stability. Better Racing.
A decade of race course innovation
MarkSetBot is the world’s first and most advanced robotic sailing mark system.
When you manage a race course in changing conditions, you need more than a robotic mark that simply holds position. You need a platform you can see, trust and rely on.
Holding a GPS position is only the beginning. MarkSetBot combines a highly visible, stable platform with steerable central propulsion, multiple layers of control and connectivity, and a complete race-management ecosystem developed through years of real-world racing.
Purpose-built for both championship racing and the realities of volunteer-run race management, every part of the MarkSetBot system is intentionally engineered to help race managers run better races with fewer resources.
Nearly 80,000 days on the water.
Used in 42 countries. Proven from local club racing to the highest levels of the sport.
That’s a Botter Way™ to manage the course.
And with 96% customer satisfaction, race managers agree.
Designed for Maximum Visibility
Easy to spot. Easy to round. Easy to trust.
MarkSetBot’s intentionally large, rounded topside isn’t cosmetic—it’s functional. Its size makes the mark easy to identify from a distance, even in chop or fading light, giving race committees confidence that competitors can see the course clearly.
Its rounded profile also eliminates protruding edges and maintains a consistent shape as the Bot holds position, giving racers a clean, predictable mark to approach and round.
Larger Visible Profile.
Larger Sponsor Opportunity.
MarkSetBot’s larger topside profile also provides visibility for sponsors. All that space becomes prime on-water real estate, turning your marks into professionally branded platforms that elevate your event while adding to your bottom line.
Engineered for Precision
Everything about MarkSetBot is intentionally engineered to improve performance while making race management easier.
MarkSetBot’s single-motor design is built for precise, efficient movement on the water. Its steerable central propulsion system delivers the right amount of thrust in exactly the direction it’s needed. This allows the Bot to move smoothly and accurately—not simply forward and backward—while making the continual adjustments required to hold position.
The result is responsive, predictable control that makes setting and adjusting the course easier for race managers.
Stability Runs Deep
MarkSetBot uses a deep-mounted, steerable central propulsion system that lowers the center of gravity and improves stability on the water. A shallower propulsion system can lose its grip in chop and struggle with current. MarkSetBot keeps the propeller immersed when waves kick up, delivering predictable control in real-world racing conditions. Combined with its wider hull, the result is greater stability and a Bot that holds position with authority.
No rocking. More reliable positioning.
A Robotic Mark You Can Rely On
The engineering matters because of what it allows race committees to do.
Change Courses Faster
Respond quickly when conditions change, reducing downtime and helping you run more races in a day.
Set Courses with Precision
Make course settings and adjustments accurately in minutes, helping maintain your intended course.
Do More with Less
Reduce the number of race committee and on-the-water support personnel needed to manage the course.
Stay Connected to Your Bots
Reliable race management depends on reliable communication and easy access to control. MarkSetBot gives race managers six ways to stay connected to and control their Bots across a wide range of racing environments.
Cellular
Dependable primary connectivity for everyday race management.
Starlink Integration
Expanded connectivity for remote and demanding environments.
HorizonLink
Long-range off-grid communication when cellular coverage isn’t available.
Bluetooth Remote
Local control when you’re close to the Bot.
SMS Control
Another layer of communication redundancy.
Stop/Anchor Buttons
Easy-to-reach buttons allow RC personnel to stop or anchor the Bot quickly.
Six layers of redundancy. One connected race-management platform.
Built for Every Course.
Proven at the Highest Levels.
From the America’s Cup to the 52 SUPER SERIES, professional race organizers choose MarkSetBot for the qualities that matter most on the water: reliability, visibility and performance.
MarkSetBot has proven itself in some of the world’s most demanding sailing environments. And that same technology is available to yacht clubs and volunteer race committees looking to run more precise, efficient and professional racing.
