SIMOON
SEMI PELAGIC TRAWL DOORS
Experience unparalleled efficiency and environmental sustainability with our latest innovation, the Simoon Semi-Pelagic Trawl Doors. Designed for the modern trawler, Simoon doors offer a groundbreaking approach to trawling, combining high performance with reduced environmental impact.
The Simoon trawl doors are crafted using the same flow booster technology that has powered our successful pelagic Twister and Tornado doors. This technology ensures that the Simoon doors achieve a high aspect ratio, which significantly increases their efficiency compared to conventional low aspect ratio bottom trawl doors. With a remarkable 3:1 ratio, these doors demonstrate an exceptionally high coefficient of lift and a high-efficiency CL/CD ratio, setting a new standard in the industry.
Simoon trawl doors are probably the semi-pelagic trawl doors with the highest spreading force available on the market today. This superior spreading power allows trawlers to use smaller doors than typically required, which in turn leads to easier towing and less fuel consumption. This feature not only enhances operational efficiency but also contributes to your vessel’s economic performance.
Designed to fly over the seabed, the Simoon doors minimize the impact on the marine environment. Their unique ability to reduce seabed footprint makes them an ideal choice for fisheries committed to sustainable practices. By choosing Simoon, you’re not only optimizing your operations but also protecting the ocean’s delicate ecosystems.
“Simoon trawl doors square very well and are significantly easier to tow than regular bottom trawl doors. The gut feeling is 20% more squaring and 5–10% easier to tow. They were good for maneuvering, easy to shoot off.”
– Remi Teistklub, Skipper Molnes
Primarily used by vessels targeting whitefish through either single rig or twin rig systems, the Simoon trawl doors are also adaptable for midwater and pelagic trawling. They are particularly well-suited for bottom-trawling at moderate to high towing speeds above 3.0 knots, offering flexibility across different fishing methodologies.
The Simoon trawl doors are designed to be easier to tow, which means they require less power and fuel. This efficiency translates into lower operational costs, making them an economically advantageous addition to any trawler’s equipment.
“The doors were stable during towing. I was surprised by how easy they were to tow and the squaring we achieved, especially with double trawling in shallow waters. Compared to similar squaring, we have reduced oil consumption without negatively impacting the fishing.”
– Jarl Kristian Synnes, Skipper Molnes
The Simoon Semi-Pelagic Trawl Doors come with adaptable features to meet various trawling conditions and extend equipment lifespan. Choose from bolted-on wear-shoes or wear-knives for enhanced durability, or select a flat wide mud-shoe for optimal performance on softer seabeds. These options ensure that the Simoon doors are tailored for maximum functionality and cost efficiency in diverse marine environments.
As a product within the esteemed Vónin family, Simoon trawl doors inherit a legacy of quality and innovation. Like all Vónin products, the Simoon doors are built to offer reliability and performance that our customers have come to expect.
