The Sea Bat is a pelagic trawl-door designed for fishery close to the surface of water as well as for fishery in deep waters. The Sea Bat is easy to use, great to shoot and hangs well in the gallows-top. The Sea Bat is great for pelagic fishery for mackerel, blue witing, herring and also for Redfish in the Irminger Sea.


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


The testimonial from the pelagic fishing vessel Finnur Fríði sums up quite well how fishing with the Sea Bat is. This is from 2009

“We are currently using a 3,200 mesh Egersund trawl and the long line is approx. 30 fathoms below the surface of the water. The trawl is incredible stable in the water, just as we like it. We have also fish in shallow waters without any problem.

We are currently fishing for mackerel and the Sea Bat’s are doing their job perfectly.

I can conclude that the trawl-doors are doing their job perfectly and we are satisfied.

(…) We have also fished for herring and Blue Withing and the trawl-doors did their job just as perfectly as with the fishery for mackerel. The trawl-doors are great and it’s good to know, for me as the captain, that the trawl-doors are made of quality hardox steel.”
