Dual role: single entity

Rauma shipyard in Finland has produced Fennica, a vessel which will function as an icebreaker in the Gulf of Bothnia during the winter, and will lay cable or deliver supplies during the summer. The ship's dual-purpose required that engineers design a hull wide enough for ice breaking, yet which would avoid the heavy rolling a wide hull would normally experience in rougher seas. Tests proved the Fennica's superb mobility and performance in both conditions.
