Mainsail Code 3C
Made in a Mylar laminate called ODL06 from Dimension Polyant. We use the 06 rather than the 04 for durability and toughness without going overboard. Being a powerful fully battened sail it needs a lot of downhaul control and along with the risk of crew crashing into the sail needs to be strong.
The sail comes complete with numbers, battens and long sail bag.
