Detailed Selling Lead Description
Subject: Flyer makes your headline fly
Message:
Vónin’s patented Flyer is a single unit clipped to the headline of a trawl
with two attachment points, and as soon as the gear starts to move
through the water, it generates lift. The Flyer has its own integral
buoyancy in the shape of two floats that form the ends of the unit, with
three hydrodynamic foils running between them.
The floats keep the Flyer afloat if the towing speed drops to zero,
keeping it clear of the trawl itself, while also serving to help it align
itself as the gear is shot away. This gives the Flyer its own inbuilt
stability, and it aligns itself automatically, producing lift in proportion to
the towing speed.
‘This is suitable for standard trawls with a single headline and also for
the shrimp trawls we supply with double headlines,’ Bogi Nón said.
Much More effective than floats
‘The unit as a whole takes up the same space on the headline of a trawl
as four 11-inch floats that provide 30kg of buoyancy, but the Flyer
produces much more lift. At 2.50 knots, it generates 90kg of lift, rising
to 120kg at 3 knots and 155kg at 3.50 knots. At 4 knots the lift
generated is 185kg, and we could go on from there, but you get the
picture.’
‘It has performed well so far and we expect this to go into production in
the second half of this year. It’s made from a very resilient material that
has strength as well as flexibility, so it can be twisted and will go back
to its original shape which means we expect it to be able to cope with
being spooled onto a net drum with the gear.’
The Flyer can sit comfortably on the wings or even the wing ends, as it
does not need to be rigged square to the flow of water to be effective.
While the Flyer is envisaged primarily for demersal gear, it could also be
useful for pelagic trawling, especially when fishing close to the surface
for mackerel.
