Yeah not a fan of a batten-less main but I do like the infinite reefing and the simple stowage and retrieval. No they don't always work perfectly and must be maintained as Scott said. I bought the boat with the original, very stretched Dacron main sail. It had lousy shape, bound due to the stretch at the foot and could not be hauled to a flat position for heavy air. I had a Paneled Tri-Radial Pentex/Technora with Tedlar UV cover made and it is awesome and fixed every problem and made it far easier to stow and retrieve. Hope this helps
