Dehler 30 OD.
The Dehler 30 OD was purpose-built for short-handed racing. Around 80 have been built, and they race all over the world.
What makes her different.
The Dehler 30 OD was designed by Judel/Vrolijk for one purpose: fast, safe, short-handed offshore racing.
Carbon-fibre and fibreglass construction

B&G autopilot and navigation systems
A data platform that happens to float.
Modern offshore racing is won on information as much as instinct. Alliance carries a full B&G instrument system – a small network of sensors that streams live data to both sailors and to the autopilot, every second of every race. Here's what's going on under the deck.
Live sensor data
Sensors at the masthead and in the hull read wind speed and angle, boat speed, heading, heel, and depth – dozens of readings a second.
An autopilot that never tires
The B&G autopilot holds wind angles (true and apparent) and heading. It's closed-loop control – read the sensors, correct the helm, hundreds of times a minute.
Racing the boat's digital twin
Every boat has polars – a performance model saying how fast she should go at every wind angle. The goal is to chase the target speed as much as possible.
Logged, replayed, improved
With our PredictWind DataHub, our races are recorded. Meaning we can replay the track and the numbers to see where we gained, where we lost, and what to change next time.
