Design & Development

  Mariner 36 4

Mariner 50 is a small coastal marine fishery vessel, which requires high standards of professional fishermen.

The vessel was designed and built in accordance with the Nordic Boat Standard 1990 rules.
Architectural solution: a mono hull with an engine room in the aft part, a cargo hold in the middle part and a pilot room with a cabin in the forward part. The cabin is equipped with berths for four people, a cook-room, a toilet.
The hull is made of aluminum alloy, which increases ratio of the payload capacity to the fuel consumption unit and reduces running coasts.
The innovative design of hull lines with a bulbous bow, provides a longer hull length on the waterline compared to a traditional hull and accordingly greater seaworthiness, a decrease in the amplitude of longitudinal pitching and improved fuel economy.
The vessel has a large working deck, two refrigerated cargo holds for fish containers or two RWS cargo holds (seawater cooling).
A fishing gear for work as a stern trawl, longline, jigging, potting, net, seine, etc can be exposed on the working deck.
The propulsion equipment installed on board corresponds to the Heavy Duty Commercial rating, with warranty support with an annual no limited operating time.
Thanks to its unique layout, the Mariner 50 is a versatile vessel and can be used for various purposes, such as a work vessel, a charter sport fishing vessel, a water taxi, etc.
The vessel can occasionally be operated in the ice brush.
Classification – CE B-Offshore, Nordic Boat Standard 1990.
