TYPE 32 BLUESTREAM – FIXED FOIL, MANUAL OR HYDRAULIC
A smart development of our well-known TYPE 22 BLUESTREAM, which has been on the marked since 2017 lead us towards the new TYPE 32 BLUESTREAM. The BLUESTREAM technology is the still key feature of the new pelagic trawl door. By developing a door with a more fluent and efficient waterflow Thyboron Trawldoor has succeeded in making an even more powerful design than the TYPE 22. The concept is simple- a door that creates greater spread with same resistance as the previous model.
From knowledge gained by CFD simulations, wind tunnel and flumetank testing we have made the new design with deeper and longer foils, when these trawl doors are towed through the water, the double foiling Bluestream-system forces water through the deep foils at higher speed thus creating a greater amount of lift while at the same time reducing drag impact.
From a testing period we have seen and gotten the feedback that this design shows to be more steady and easy handling than the previous TYPE 22.
As one of our patented features, the TYPE 32 BLUESTREAM also comes as a FLIPPER model. The FLIPPER system has also gone through an improving development since we have now made the flaps much easier to use and it is now possible to have it as either a manual solution or a hydraulic solution.
Both options are easier than the old system to operate from the vessel without any dangerous moves outside the vessel. The manual solution is operated by two springlocks on each foil that helps to open / close the foil and locked in the wanted positioning. The hydraulic system allows the fisherman to positioning the foils with only a few push on a hydraulic pump.
With the flipper function it is possible to reduce the spreading power of the trawl door by easily closing 1 or 2 flaps in the door. This system offers a lot of adjustment possibilities for many different fishing setups and provides extremely high stability when fishing deep or fishing very close to the surface with a lot of turns. Furthermore, this feature can increase the efficiency of the trawl doors even more than with only the BLUESTREAM technology implemented.
