I have found that minimizing the last purchase of the outhaul greatly increases the ability with which it can be eased or trimmed. For example, you could have a 4:1 pulling a 2:1 and then to the sail for an 8:1. Or better yet, you could have a 2:1 pulling a 4:1, for an 8:1 as well. The latter example will ease better in light air. Trust me. I’m a doctor… sort of. We built an outhaul like this on a SC50 with a long boom. We built a 2:1, pulling a 3:1, pulling a 3:1 for a total of an 18:1. I can pull it on upwind in heavy air and it eases well in light air.
