DGzRS prototype — 12.75 m twin-jet sea rescue boat
The German Maritime Search and Rescue Service (DGzRS) commissioned a new prototype to replace their proven 9.5/10.1-meter class vessels. The goal was to develop a completely new class that maintained high seaworthiness while offering improved speed and maneuverability. Key requirements included separating the drive train from the control station to reduce noise and facilitate medical evacuations.
Our design process prioritized iterative testing and ergonomic validation to meet the rescuers' strict demands. We utilized a full-scale wooden mock-up to confirm excellent all-round visibility and optimize the control station layout for the volunteer crews. Additionally, tank tests at Aalto University validated the hull’s seakeeping performance before construction began.
The vessel is constructed from glass- and carbon-fiber-reinforced plastic (GFRP/CFRP), offering a lightweight yet robust alternative to aluminum. This material choice allows for flexible spatial design and reduced maintenance costs. The deckhouse is fully elastically mounted to further minimize noise and vibration, while suspended seats provide safety for the entire crew.
Propulsion is provided by a twin-jet system with 425 hp Cummins engines, delivering speeds over 34 knots and allowing operation in shallow waters. The boat features advanced safety systems, including a low-lying rescue platform and an automatic positioning system that allows the foreman to switch control positions. This prototype represents the future of maritime safety for the North and Baltic Seas.
