The
Stormfageln prototype is a Swedish design which was originally
created to develop future solutions for environmentally sensitive
and fuel-efficient boats. The Stormfageln's inventor is Torbjörn
Eriksson a third-generation sailor keen to help reduce damaging
pollution in the world's seas, while also providing a fuel efficient
(and therefore cheaper) alternative to current watercraft.
The Stormfågeln is based on a patented hull design with
two surface-piercing propellers and three-point contact hull
which reduces surface friction.
Surface piercing propellors have been around for a while now,
and although they have several benefits including lower water
resistance, and minimal cavitation around the propeller blades,
which together allow for higher speeds, they also have some
drawbacks including; a tendency to lift the stern of the boat,
reduced maneuverability while reversing, and the fact that they
are only suitable for lightweight boats.
Stormfågeln's solutions of surface-piercing propeller technology
– which includes the complete propulsion system and the hull
design – allows the boat to plane almost immediately, this means
that the system can be used with significantly heavier boats.
At the same time, the tendency to lift the stern is counteracted,
and this gives a more stable attitude during high speed travel.
The reverse-enabled propeller blades eliminate maneuver problems
previously experienced during reversing. The design of the propulsion
system means that the engines operate at low rpm, even at high
speeds, and this helps significantly reduce fuel consumption.
When the unique drive system is coupled with the clever hull
design the end result is a much softer, smoother ride than conventional
hull watercraft, with close to no wave creation, and the ability
to achieve high speeds with rapid acceleration.
