I have an M15 without sail slugs and am perfectly happy with it.I rarely have any issues with the bolt rope. I do believe that as the boat gets bigger sail slugs become more of a neccessity. I have been sailing J22's and Catalinia 25s with sail slugs and am puzzeled about reefing a main with sail slugs. How do you do it? There seems to be a stack of sail slugs 1 1/2 fot high at the tack. How do you get the the reefing tack secured and a good tight outhaul without putting excess strain on the the first slug above the reefing tack? The Catalinia 25 had a slug removed so the reefing tack would reach down to a tack hook. If this is a common practice how do you do a second reef? It seems that the stack of slugs is now 3 ft high. What am I missing? Thanks Doug Kelch M15 #310 "Seas the Day"
