In an attempt to keep on topic - I'll post my question here:
I have two Famet Roller furling units - Type A and B. The main difference between the two is the internal halyard hole for the units to mount around the forestay - Type A has an 8mm hole to take 5-7mm forestay wires and Type B has a 14mm hole to take 8-12mm wires.
Here's my question - I have a 7mm wire, which would seem to dictate the Type A. My issue is it's off my old boat and was my staysail rig, so on the Yorktown 35 I'm trying to resurrect, it will be approx 7 feet shorter than I desire ( I need 40', the Type A is 33'), which would limit the amount of sail I can carry forward. The Type B is long enough (actually 46' and I can remove 2-3' sections to match perfectly) and I have an offshore sail that would match my foretriangle perfectly. I'm wondering if the difference between a 7 & 8mm wire would be great enough to stop me from going ahead and using the Type B unit on my headstay - any riggers out there or people in the know that could help me here?
These are really robust units and don't really flex, so outside of rattling about a bit, i'm unclear if there would be any downside. They were bulletproof on a previous boat so I'd love to use one on this one. Would sure appreciate any advice folks may have. Thanks!
