Sentenal replaces traditional buoys with self-navigating marks that hold station precisely — windward-leeward, triangle, or custom layouts. Reposition the entire course on demand instead of spending 10–30+ minutes resetting by hand.
Sentenal is a smart, self-navigating robotic platform designed for open water yacht, canoeing, and rowing events — and sailing regattas of every format. It replaces traditional buoys with precise, quick, and easy deployment, allowing race officers to focus fully on managing the race.
Simply place the Sentenals in the water and activate AutoNav. The system reliably drives them out to your pre-determined positions, holds station accurately, and waits for the next command. You remain in full control without towing markers or worrying about position changes during the race.

Deploy from the marina, dock, or RIB with one or two people. Modular assembly and stackable design make setup fast and transport practical.
Select a path and fleet, set start and end points, and the Sentenals move together in an orderly line — no support boat required.
Each mark holds station at its assigned role. Build windward-leeward, triangle, or custom layouts in Layout Mode on the interactive map.
Breeze shifted? Move the whole course or individual marks in under two minutes — ideal for wind shifts and back-to-back races.
Reposition the full course in under two minutes — ideal for wind shifts and back-to-back races, compared with 10–30+ minutes traditionally.
Set safe, pre-defined corridors on the map that the fleet follows to course positions — avoiding other boats, moorings, and hazards during deployment.
Visual waypoints show the route on the map. Live Stop and Slow Mode controls give you safety and precision at any moment.

In Layout Mode, you build and manage race courses directly on an interactive map. Assign Sentenals to roles — windward mark, leeward gate, offset mark — and adjust course variables in real time with full, safe operation of the fleet on the water.
Channel Control lets you define safe corridors that Sentenals follow when heading to their course positions. The result is clear, predictable, and controlled navigation — making it safe to send multiple marks out to set up the course.
As the race officer, you can reference these channels in the Sailing Instructions, so competitors know to stay aware of them during deployment and racing.
