This unique boat is the first of its class and is designed as a streamer support boat for operations offshore with seismic survey ships. She is designed with a single point lift arrangement to allow her to be davit launched and recovered from the mother ship whilst underway and deployed for streamer handling operations. She is very robustly built yet through careful weight control and structural optimization she comes in at under 7 tonnes when light and she packs a surprising amount of equipment including a complex hydraulics package into a very compact arrangement. She is fitted with twin Yanmar 240bhp engines and Ultrajet 305 waterjets which give her excellent slow speed manoeuvrability as well as a top speed of over 20 knots and a bollard pull of nearly 2 tonnes. Her hull form was extensively model tested at Newcastle University and she is very stable and exceptionally seaworthy to allow her to offer maximum performance offshore.
