The Sea Hunter is designed for bottom fishing and bottom trawls, where the trawl-doors can be used without weights behind the doors. What characterizes the Sea Hunter is that it spreads the trawl very well, is stable and keeps its position in the water, even when the doors are going above the seabed. The Sea Hunter is effortless to haul and turn with, and is energy efficient. The Sea Hunter is also used for fishery on soft seabed, where the doors need to be kept some meters above the seabed. The Sea Hunter has also, in few cases, been used in fishery for prawns in the Barents Sea.


The Sea Hunter is manufactured from high quality Hardox 450 and S355 steel.


Markus, a trawler from Greenland, was the first to use the Sea Hunter. In 2016 they ordered a new sett of the Sea Hunter. The testimonial from the captain of Markus sums up quit well how good the trawl-doors are.

“I can’t say more about the trawl-doors than; they are great to shoot to tow and haul. The doors spread well and are actually the best trawl-doors we have had. They are at full spread even before the trawls reach the bottom. They hang well in the gallows and are great to work with.

We have been fishing for 10 days; the weather is good, as it was on our last fishing trip. The fact is that, compared to our last fishing trip, we are down from 16,500 liters/day to 15,800 liters/day. A 5 % fuel deduction so far.”
