Time to get some new shrouds for our J24. We have had the 5mm Dyform, open-turnbuckle type on there since the late 90s. They are kinked, tired, and the fittings look to be pretty damn clapped out, so I think it's high time for a new set. Questions:
1. Ought I to stick with Dyform cables, or go to the regular 3/16" cables? My understanding is that the plain 3/16" type are lighter and easier on the genoa, but that they do stretch more because there is more cross-sectional area. I'm not sure it makes much of a difference other than at the world-class level, but if so it would be great to know.
2. Perhaps more importantly, should I stick with open turnbuckles or go for those sexy Ronstan calibrated turnbuckles with handles? They look like an excellent product and I've seen them at regattas, but I don't know anyone who has them locally. I am thinking that the ability to change shroud tension in a jif without tools, and without having to muck around with those velcro scar pin things to hold them from rotating, could prove a huge convenience and timesaver, and reduce the risk of dropping wrenches overboard. Is there a downside to them? Will the spin pole clip on around the fatter base, especially if said base has the fold-down handle on it?
Thanks for any thoughts.
I can't seem to find Dyform readily available these days - I can tell you though that the sexy ronston turnbuckles / handles are excellent and are much easier than dealing w/ wrenches - many of the U20's have them today and your rigging supplier should be able to purchase them for you. Can't comment on the spin pole as we run a sprit -
