Daggerboards delivered for innovative RoRo ships
Becker Marine Systems delivers Anti-Drift Daggerboards for innovative RoRo vessels with wind propulsion.
Another exciting project has left our premises: In calendar week 15, the two Daggerboards were successfully delivered.
The RoRo vessels are being built for the French shipping company Louis Dreyfus Armateurs (LDA) and will transport aircraft sections from France to the final assembly line in Mobile, Alabama (USA). The first vessel is expected to enter service by the end of this year.
Becker Marine Systems is supplying a foldable “jack-knife” daggerboard system. Key technical specifications:
- Fin area: 8.8 m²
- Lift force: 300 kN at 8° and 14 knots (per ship)
As the Wind Assisted Propulsion System (WAPS), the vessels will be equipped with six Flettner rotors. This combination of wind support and our Anti-Drift Daggerboards significantly boosts efficiency and reduces emissions.
We are proud to contribute to sustainable shipping with our technology – and to be part of this forward-thinking project.
What is a Daggerboard?
The daggerboard developed by Becker is an Anti-Drift Device – a passive, retractable fin system that reduces the vessel’s lateral drift caused by crosswinds or thrust from a Wind Assisted Propulsion System such as Flettner rotors. Thanks to its special geometry and strategic underwater positioning, it generates lift that counteracts lateral movement. This not only stabilizes the course but also improves fuel efficiency – making it a key contributor to the overall performance of wind-assisted propulsion systems.
