The Blue 8.25 Mainsail is the latest generation Moth sail. The luff tube and deck sweeper are now moulded with the sail to produce a uniquely fair flying shape, with no seams across the flying surface. Camber inducers have been removed and replaced with split battens, which further enhance the flying shape & usability. The sail is designed to approx. 8.25 square meters area, and the largest sail in our range.
