With the traveler the “twist” of the mainsail can be adjusted, so that the mainsail brings either more or less power. This significantly optimizes the sail trim and can be adapted to the current course and wind conditions.

Sailing downwind, by means of the mainsheet traveller the main can be hauled in tight towards luff for enhanced leech tension. That ensures good close hauled setting of the top part of the mainsail “Square-Head”, without allowing the wind pressure to open the lower parts (twist) of the mainsail.

On downwind you can set the traveller to lee and tighten main sheet. This will tension the leech of the mainsail and “close” the top “square head” of the main sail. This prevents a “twisted” main sail top.

Whether you want to sail sportive or relaxed, can be influenced with the Traveler. Under conditions of light winds the traveller may be set windward, allowing to sail closer to the wind (that raises helm pressure). For sportive sailing on one hull, the same setting may be applied, whereby the windward hull easier lifts off from the water.

If sailing under conditions of stronger wind, with particular intension to reduce the risk of capsize, the traveller setting towards lee (the side where the wind blows to) may be preferred, which reduces helm pressure and weather-helm (drag towards the windward side). The catamaran will sail safely and smoother in this configuration.

When sailing under conditions of plenty of wind close hauled, the centre of pressure can be moved farther backwards. The traveller shall be set close hauled, but the mainsheet can be opened a bit.
