Ekkó's advantages

  • The Ekkó trawl doors catch well
  • The Ekkó Semi doors are pulled at only 20°-°25 angle of attact and saves fuel
  • Inside the top of the Ekkó door is an airlock that helps when fishing in shallow waters
  • The airlock helps manage the fishing depth during pelagic fishing
  • The Ekkó Semi door seldom touches the bottom and protects the ecosystem at the bottom
  • The Ekkó doors reduces the carbon footprint of the fishing industry

The Ekkó patents are already confirmed in the United States, Iceland, Denmark, Faroe Islands, Greenland, France, United Kingdom, Russia, Australia and China. In international process in more countries.


  • The wing-shaped shape of Ekkó, spreads itself out with the Bernoulli forces.
  • Airlock, good in shallow waters.  With a relatively long warp out, the doors are more stable with the air lock active.
  • The airlock controls whether the Ekkó pelagic trawl door is fishing near the surface or deeper.
  • The weight adjustment system,  easier to add weight to the doors temporarily.
  • Front straps connection to the trawl (in stead of backstraps connection),  suitable on trawlers that take up the doors on the site,  as is common in some countries.  Saves energy.
  • Applications have been processed and confirmed in USA, Iceland, Denmark, Faroe Islands, Greenland, France, United Kingdom, Russia, Australia and China. All approved.

Saves fuel

  • Due to the wing-shaped profile of Ekkó, it travels quietly through the sea at a smaller angle of attack than other brands.
  • The resistance is low because Ekkó is thicker at the front and then tapers back like an airplane wing.
  • The lifting force of the wing-shaped Ekkó´s profile is high because the back plate is sharper and longer than the front plate. Therefore, the sea has to travel longer and at a higher speed,  which results in low pressure at the back plate and high pressure at the front plate,  and the Bernoulli forces pull the doors out on their own,  without having to force the doors out at a large angle of attack like other doors.


With the airlock active in shallow waters, the Ekkó doors stand even better.
When the inner door almost stops while turning, the air inside the top of the door keeps it in an upright position.
The airlock is activated by simply inserting a screw bolt into the top plate.  To deactivate the airlock,  remove
the screw bolt from the top plate.
The airlock is relatively larger in Ekkó´s pelagic trawl doors.
The airlock controls whether the Ekkó pelagic doors are fishing near the surface or deeper.


Weight can be added-on temporarily to the Ekkó doors and lightened again at will.  
By unscrewing a lit and placing old chains inside a closed compartment between the two parts of the
wing layers of the Ekkó trawl doors.
This door weighs 1500 kilograms and can be temporarily weighed around 1700 kilograms.

Extensive experience in the fishing industry

Mr. Smári Jósafatsson

The Ekkó trawl door is an Icelandic design from decades of experience.  The designer of Ekkó is Smári Jósafatsson.  Smári worked for decades with his father Jósafat Hinriksson,  the maker of the Poly-Ice trawl doors.  Making them,  in research and development, and as sales and marketing manager.

Making them, in research and development, and as sales and marketing manager of the Poly-Ice trawl doors which were among the best-selling trawl doors in the world at that time. Accumulating years of experience in the industry and the technology.  

Out of the experience and observations on the limitations presented in existing trawl doors he decided to start research and pursue his vision of the EKKÓ shape.
