The boat was designed and constructed by Mundal Boat, a specialist in large innovative vessels made with sandwich composite material.

M/S Bluefin is a purse seiner, an effective type of vessel to catch aggregating species near the surface. A purse seiner fishes with a net called a seine that is laid out in a circle around a school of fish and drawn into a purse that closes the bottom, trapping the catch inside. The boat must be stable since it has to carry a heavy load.

M/S Bluefin is owned by Nye Bluefin AS in Nekkøy, was built in 2000 and then extended twice, in 2005 and 2006. In 2013 a decision was made to further extend the boat, adding 7.8 meters midship to increase the hold capacity. The boat was originally designed and constructed by Mundal Boat, a quality provider of commercial vessels established in 1981 in Sæbøvågen, Norway. Mundal Boat also took care of each of the rebuildings. The company is well known for first-class work and has been cooperating with DIAB for more than 30 years.

The specialty of Mundal Boat is design and construction of large innovative vessels in sandwich composite material. Composite boats are more durable and more economically effective than their wooden or steel-clad counterparts. As wooden and steel-clad boats are much heavier, they cannot reach such a high speed with the same engine. So the first benefit is that the boat uses much less oil for each journey.

In M/S Bluefin, Divinycell core material is used throughout the entire vessel. Used in conjunction with strong laminate, it offers the ideal combination of strength, stiffness and roughness.

During the latest rebuilding, where all the design and dimensioning were provided by Maritime Engineering AS, M/S Bluefin was extended with a new middle section using Divinycell core material. Three new cargo holds were added and the total load capacity is now 300 m3. The rebuilt seiner features a new deckhouse on the port side and an extended dayroom. It is now equipped for 11 people and will operate traditional inshore fishing.
