To maximise the performance of the Rock, a little attention to how you set the sail will be necessary. However much conditions are firing, an extra few seconds spent checking the settings can be the difference between a good and a bad session on the water. "Since joining Tushingham I've seen how Ken Black has sharpened the Rock, bringing more, power, delivered faster and helping me go BIGGER whenever I want to!" - Chris "MUZZA" Murray "The Rock is a great choice for those who are looking for easy going characteristics and high build quality" – Boardseeker Magazine "A very well built sail with a fantastic natural and tuneable range that is user-friendly for a massive range of abilities" - Windsurf Magazine Rock Mast selection: Rock Mast selection: For extreme wave use we highly recommend the RD Wave and RD 60 masts.
