76m2 multi-species Canadian freezer trawler Saputi, owned by Qikiqtaaluk Fisheries Corporation operates alongside the Canadian coast, fishing for shrimp and turbot.

SAPUTI succesfully tested the Thyboron trawl doors on a trip with bad weather in January and February, fishing for shrimps

Feedback from the Captain of Saputi, Danjal Niclasen:

“We tried the new thyboron  doors last trip and we’re very happy with the results. Saputi is an old lady now and under powered. We have been looking for something easier to tow and hold a good spread. The new Thyporon doors did just that. Towing in ice we had trouble keeping the pressure on our doors but these doors have the stability of a conventional bottom trawl door and the spreading force of the pelagic doors and we also used less wire ratio. So over all, we got more spread and they were easier to tow, so we had better catch rates”

By understanding the needs of fishermen operations Thyboron Trawldoors develops.

The main plates in the 10m2 big trawl door are made in high tension HARDOX450 steel, ensuring a strong construction.

The custom aspect ratio gives a perfect balance of weight because keeping a low center of gravity is essential.

The door is compact and extremely steady while keeping spread and posture intact both during turns and straight tows.

These doors can be operated with both 2 and 3 backstraps.

The CL/CD on 5.93 from this BLUESTREAM design is the highest on the marked for a semi-pelagic trawldoor and keeping the CD as low as possible, leaving this door close to twice as efficient as the big and heavy regular bottom doors.
