Seth pretty well says it all.I added slides to my main and a used Harken Furler last year.It came with a 140 % dacron jib and is great for cruising and the odd race if conditions are right and I am really short handed.Fun but not too competitive.I`m having an older 163 cut to fit the furler but won`t put on any anti uv stuff so it will have to come off the furler at the end of the day.I think the furler is great and ,yes,the expense is there but what else is more fun to dump money into.Clive Johnston
