Product Description
The SW-4 is a powerful mainsail which is slightly more full than the PR-3. This sail is designed as an all-purpose sail with an emphasis on moderate and heavy air. The SW-4 is deeper in the bottom compared to the PR-3, but twists easily to make the sail very forgiving to trim, especially in choppy conditions when the boat and sail is moving in the waves. Larger teams will want to choose the SW-4 for more power even in light wind.
