Trade sail
The trade sail , also known as a twin foresail , is a combination of two foresails that is particularly suitable for sailing with the wind from behind on long stretches, for example with the trade wind when crossing the Atlantic from east to west. Two genoa or one genoa and a large light jib are used . Since the pressure point on the sail is far forward, the ship is easy to steer. To prevent the sails from collapsing, each sail is expanded with a tree . The two sails and the two trees are difficult to handle when the swell is strong and the ship is rolling accordingly.
A parasail is more effective and easier .
In the past, before there were wind vane controls , sailing ships were steered directly via the sails on downwind courses. For this purpose, the pods were connected to the tiller, suitably stocky. The ship then steered after the wind in the event of wind changes or displacement caused by waves.
Passat sailing should not be confused with butterfly sails , which require careful steering and are not suitable for long distances or in swell. Downwind -Sailing is always faster, but also requires more attention.
