CTruk Kicks Off Work on Enhanced SWATH Workboat

CTruk has utilised the wealth of performance statistics and operational feedback gained during its composite SWATH workboat CWind Astute’s first year at sea to fine tune the design for the next build.

The Brightlingsea yard has recently started work on a 20m SWATH OWSV for Dungeness-based Technical Marine Support and CWind under the latter’s boat share scheme.

The use of waterjets is the main difference on the new SWATH (small waterplane area twin hull) workboat. Rolls-Royce Kamewa FF41 jets are expected to increase the vessel’s manoeuvrability as well as responsiveness to sea conditions when approaching the turbine transition piece.

A revised engine and transmission layout will optimise the base vessel’s longitudinal centre of gravity (LCG), meaning ballast volumes are reduced and the entire vessel is lighter.

Coupled with the weight savings already gained from composite construction, this will serve to further enhance the fuel efficiency for which CTruk’s innovative workboats are renowned.

The new design’s refined hull shape also gives extra displacement, optimising inherent versatility with the option to carry more weight. The ability to reduce draft if required will also allow the craft access to shallow harbours and to beach safely.

End user feedback has resulted in a more ergonomic wheelhouse console arrangement, with slightly increased height expected to positively impact operator fatigue in harsh conditions. The (removable) passenger pod is also longer, for heightened passenger comfort and increased stowage. As with CTruk’s popular 20T multi-purpose catamaran, the deck modules can be moved or even lifted off to offer true multi-role capability.

The vessel is due for delivery in March 2014.
