The platformOne robotic mark. The whole course, handled.
Sentenal replaces traditional buoys with a self-navigating mark you can deploy, position, and move on demand — bringing dependable autonomy to race management while staying deliberately simple to run.

One or two people assemble and drop the fleet in from shore, dock or RIB.
Activate AutoNav and the fleet drives itself to the course in an orderly line.
Each mark holds station within metres, holding the course precisely.
Shift the whole course, or any mark, in under two minutes as conditions change.
Place the Sentenals in the water and activate AutoNav. The system reliably drives them from the marina out to your pre-determined positions and holds station — you stay in full control without towing markers or chasing position changes.
As the only marks on the course, Sentenals deliver total consistency. Reposition the entire course — or a single mark — quickly and precisely, keeping everything aligned when the breeze shifts or you run races back to back.
Swimmers and crews come first. Protected thrusters minimise the risk of contact, and redundant navigation, power and communications keep the fleet predictable when conditions turn.
Sentenal comes in 1 meter, 1.2 meter, 1.5 meter and 3 meter hulls — with a 4 meter in development — and is built to be lived with: modular assembly, quick part swaps, and a stackable shape that makes storage and transport effortless. Interchangeable top covers, in a range of shapes and colours, swap in seconds to suit any conditions.
Every Sentenal at a glance — name, battery, and online status. Add or remove bots in a tap.
Set a path and fleet, and the bots move together from marina to course, no support boat.
Build and adjust race courses on an interactive map, assigning marks to roles in real time.
Set safe corridors the fleet follows, avoiding boats, moorings and hazards on the way out.
