Please be aware that IBI Sailing are the sole importers of J Sails in the UK. J Sails sold by other companies are not sold with the blessing or knowledge of J Sail in Poland. You will have difficulties if there are warranty problems. The Black is similar to the Red but is deeper in the head of the sail for more power in lighter conditions. It is ideal for sailors of 50 kg and over. The Classic JSails allow extremely high pointing which is vital when on a crowded start line. Comes with sail bag, sail numbers, measurement certificate, sail ties. Application of numbers needs to be ordered separately (Product No. 2736). Sail numbers only available in blue.
