Semi Pelagic Range
Semi Demersal
Single spoiler semi-pelagic models designed for demersal fishing with reduced drag and exceptional stability.
Semi-Pelagic Design
The Smart-Choice semi-pelagic trawl door features a single spoiler design that operates at approximately 20° angle of attack. This innovative approach significantly reduces drag while maintaining strong spreading force.
Based on the Bernoulli principle, the hydrodynamic design generates lift efficiently, allowing the doors to fly steadily just above the seabed — protecting benthic ecosystems while maximizing catch performance.
~20° angle of attack — reduced drag, increased efficiency
