Construction 2nd Monomaran started.


Last week Next Generation shipyard started with the building of the 2nd Monomaran for Coastwise Offshore Services. The vessel will be built under the name “COS Mate” and is a full sister vessel of the Next Generation Shipyards Endurance class type NG 2727.

The contract involves a special new type of vessel which combines the stability of a catamaran with the speed and fuel efficiency of a monohull.

The design provides the stability of a traditional catamaran and the speed and fuel efficiency of a monohull.

This combination is reflected in the name under which the new type of vessel is put onto the market: 30 Pax Monomaran Crewtender – Endurance class NG2727. The vessel will be delivered to Coastwise Q3-2022 and sail under the name of COS Mate. The aluminium vessel is over 27 metres long, provides ample and comfortable room for 30 passengers and can carry a load of 15 to 22 tons. It will be fitted with a deck crane. Its cruising speed is 27 knots. The design is innovative and sustainable, which means that Next Generation Shipyards presents a concept which appeals to the market and symbolises the role which the Groningen region wishes to play in the field of energy transition and renewable energy.

Once the vessels have been completed, Coastwise Offshore Services will outsource the commercial management of the Monomaran Crewtender to SeaZip Offshore Service in Harlingen.
