Yes. Performance depends not on maximum lift but on the lift-to-drag ratio in real sailing conditions.
When underway, a ship creates apparent wind equal to its speed, adding to the true wind, meaning the vessel sails mostly close-hauled.
At close-hauled courses, Cormoran wings have the best lift-to-drag ratio among sail technologies.
In headwind, the wings fold down and generate no drag.
To avoid installing actuators high above deck, minimizing emergency intervention risks. All actuators are accessible from the deck regardless of conditions.
The metallic structure safely conducts the electrical discharge to the ship’s hull.
The wings’ weight is a very small fraction of vessel displacement, even for sail-assisted ships.
In strong wind, wings fold down, lowering their center of gravity and eliminating drag.
Stability is verified early; usually, no modifications are needed.
Heel is perceptible close-hauled in strong wind on heavily sail-assisted ships but usually does not exceed 3°.
Heel can be limited by adjusting the base plate in the wheelhouse. Wings also significantly reduce roll once raised, even without wind.
Cormoran wings greatly dampen roll when raised.
In no wind and beam seas, keeping wings raised stabilizes roll.
With aft wheelhouses, forward visibility regulations are met.
If needed, cameras with bridge transmission and automatic obstacle detection can be installed.
The wings produce 200 W/m² under optimal conditions.
We can calculate the expected average output based on your vessel’s route.
The panels generate electricity whenever there is a light source, whether the ship is at sea or in port.
They even produce electricity on cloudy days and at night when the moon is shining.
Yes, we offer wings with or without solar panels. However, note that the return on investment for solar panels is very quick.
Maintenance is minimal and no more frequent than for a ship’s crane: greasing the axes, periodic replacement of hydraulic hoses, and inspection of bearing wear every five years.
No. The rigid wing is built with durable components, each with a lifespan exceeding 15 years.
The entire wing is designed for a 25-year lifespan, except the solar panels which are estimated to last 15 years.
Yes. The Cormoran wing is designed and certified for installation on vessels operating in polar regions.
The solar panels perform reliably in cold temperatures and at high latitudes.
