Sentenal is the autonomous race-mark product line of BlueSense Ltd — designed by New Zealanders, tested on the water, and built to make race days simpler, safer, and fairer.
We understand the pressure on race organisers to deliver safe, fair, and memorable events. Sentenal exists to take the stress out of course management — so teams can focus entirely on the athletes and the quality of the racing.
No complex menus. No unnecessary features. Just robust, fault-tolerant technology that performs when the weather turns and the race clock is running.

Built and refined for the toughest environments on the water, by people who know racing.
Redundant navigation, power, and comms keep the fleet working when conditions are demanding.
Hardware, software, and autonomy tested with direct input from race officers, volunteers, and clubs.
"Because it all comes back to the swimmers, sailors, and crews. Welcome to smarter race management."
