About

Kiwi-built autonomy for the world's racecourses.

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.

Our philosophy

Keep it simple, Keep it reliable.

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.

How we build

Refined on the water, with the people who race.

Designed in New Zealand

Built and refined for the toughest environments on the water, by people who know racing.

Tough and fault-tolerant

Redundant navigation, power, and comms keep the fleet working when conditions are demanding.

Proven with race teams

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."
