Thanks, all, for the rapid and useful responses – especially the photos. The fairlead/ratchet set up looks sensible and should really improve the ease at which we can sheet in on the beats. I think that will be the first improvement to make. The small jib is also a good idea, I think, though I’m not sure the budget will stretch to both.
The reason I asked about 2:1 was that I had heard that Mike and Rani Pert used some kind of purchase system on their genoa sheeting and I assumed it was a 2:1. (Often they have visited our club ( Aldeburgh) for the annual regatta but so far I never got close enough to see it … on the water at least!) 🙂 .
