Yes, I am pleased with my reefing furler, and the new genoa too. I’ll give you some more detailed feedback via email. I am still undecided about the best way to adjust rig tension – Highfield lever is not really feasible with integral forestay as there is nothing to pull on to ‘help’ the Highfield achieve full tension – but thank you for the information about muscle box options (and alternatives).
As you know I bought my sails from Mike McNamara, and asked him to make a tubular cover for the genoa. It’s breathable and closes with a full-length zip. The only improvement I would make would be to increase the length of the cover slightly.
