For Sale: MCA Commercially Coded 9 m Ocean Dynamics Ribworker Aluminium Diesel Jet RIB (440 HP / 324 KW)

Ocean Dynamics Ribworker jet boat for salePassenger and workboat coded Ribworker: 12 passengers plus 2 crew or 1000 kg cargo or combination, Yanmar 6LY2A-STP 440 HP (1650 hours), Hamilton 274 water jet, aluminium hull.

Fast and fun passenger RIB, capable of power-braking or spinning on its axis – slowly for precision manoeuvring, faster for jet boat spins for exciting passenger trips.

Excellent workboat: towing, precision manoeuvring even at slow speeds in strong tides, pushing and simply carrying gear, operates safely in just 0.45 m of water. Ideal dive and rescue boat, with an unusual amount of deck and storage space, no propellers so huge safety and operational advantages.

Ribworkers are known for versatility, manoeuvrability, strength and longevity. Shearwater is an excellent example of a Ribworker, very nimble and responsive for a RIB her size and very economical on fuel (red diesel).

Price negotiable according to buyer's requirements for equipment and spares, training and ongoing support (if any).

No VAT to add if buyer purchases boat with business - please see business sale particulars page for details.

Please note: the refit gallery shows the refitting of Atlantic Eagle / Brandaris II, the first 9m Ribworker, not Shearwater, the boat we have for sale. It is the same make, model and size as Shearwater - a 9m Eagle Class Ocean Dynamics Ribworker - but older (36 years old) still working as a salvage and support vessel in the North Sea.

Photos of Brandaris II are included here to show one of many refit options for the 9m Eagle class Ribworker - from an open to a cabin RIB. Aluminium is tremendously versatile; one of the Ribworker's strengths is that they can be refitted to suit new owners.
