The HL-78 type is taken the pelagic trawl door to the next level. The HL-78 has an extremely high lift (spreading power) with low resistance at the same time. The genius designed outer foils, together with the placement of the inner foils make it very easy for vessel to turn and turn fast while towing, without loosing any precious time while fishing. As the HL-78 model is so powerful, it makes it easy and safe to offer smaller sizes of HL-78 when comparing with other models on the market. The HL-78 aspect ratio is 1:1,78
