Newbuild North Sea beam trawler has twin Optima nozzles

MAY 7, 2018 — Hakvoort Brothers, based in Urk, the Netherlands, has taken delivery of UK 46, the first new beam trawler built for the North Sea in twelve years. The vessel was outfitted by Damen Maaskant Shipyards Stellendam over the past ten months using a 41-m hull from stock.

Beam trawlers use outrigger booms to tow two trawls, one on each side. In the North Sea they are commonly used to catch shrimp and flatfish. The last such fishing boat to join the Dutch fishing fleet was the Catharina KW-145, launched in 2006. Prior to that, Maaskant delivered two others; the Cornelia BR-14 in 2004 and the Jan Cornelis GO-22 in 2006. Both these were also built to the Damen Maaskant design.

A key feature of the newly delivered UK 46 vessel is the installation of twin Optima nozzles manufactured by Damen Marine Components (DMC). This is the first time that Maaskant has installed these in a fishing boat.

Optima nozzles manufactured by DMC lowresThe nozzles are Damen Optima L/D 0.4 models with a diameter of 3.63 m.

The stainless-steel collars surrounding the propellers deliver improved thrust both ahead and astern and so require less engine output for a given speed. In addition, they also enhance performance at low speeds and give less resistance at higher speeds.

The vessel's fishing winch also represents a milestone for both Maaskant and DMC. It is the first such winch to be manufactured by DMC and was built to a design by Maaskant. A third Damen company also played a role in the fit-out of UK 46, with Damen Anchor & Chains supplying its trademark products to the vessel.

"It's been a real pleasure to complete this trawler and see her afloat at last, and to work with our sister companies to make it a success," says Eric Moerkerk, deputy director at Damen Maaskant Shipyards Stellendam. "The hull has been here at Maaskant for more than ten years and we have long looked forward to it being out at sea where it belongs. This is the first time that we have fitted a trawler with nozzles and while it is early days for the vessel, the indications are that she is working well and the nozzles are delivering the expected efficiencies. The next three fishing boats that we will be building will also be fitted with nozzles from DMC."
