ALTAIRE Shetland fishing Karstensen

Karstensen Shipyard delivered the new 79.95-metre ALTAIRE, a pelagic trawler, to Altaire Fishing of Shetland at the end of June 2023

Newbuilding 469 “ALTAIRE” was handed over to owners Altaire Fishing Co of Shetland on 29 June 2023 from Karstensen Shipyard.

The hull for “ALTAIRE” was built by Karstensen Shipyard Poland in Gdynia, and arrived in Skagen in November 2022.

New “ALTAIRE” replaces skipper Chris Duncans previous command of the same name. The new vessel will operate along the same pattern as the existing vessel, with a traditional pelagic trawl fishery, where target species are mackerel and herring.

Altaire Fishing Company is owned by Interfish of Plymouth, headed by Jan Colam together with skipper Chris Duncan and chief engineer Ivan Reid both from Shetland.

Karstensen Shipyard is very proud with the new delivery, which continues long standing working relations with both Mr Colam and Altaire Fishing Company. Cooperation has been with maintenance and repairs on “Altaire” for a good few years. And with newbuilding of KS-465 “Artemis” which is jointly owned by Interfish and Wiseman Fishing Company.

The vessel design, specification and arrangements is a result of an extensive and close cooperation between owners and yard where all solutions are optimized and tailor made to suit owners and crews specific requirements.

Main focus has been set on optimizing working, safety and comfort for the crew, optimizing catch handling- and storage facilities and optimizing of fuel consumption. In order to reach above targets, the vessel is fitted out with all the newest developed machinery and equipment.
