    Default 7/16" 7x19 IWRC vs. 3/8" 1x19

    The original 1931 rig on the schooner had all kinds of different sizes of wire rope, but since 1939 has had 3/8" 1x19 everywhere except the bobstay. First, galvanized wire rope, then stainless. Well, the stainless is shot and we're going back to galvanized with the re-launch but I can't imagine an inexperienced wire-rope splicer (me) doing a good job with 1x19. But, I note that though it's more flexible, the easier to splice 7x19 IWRC in 7/16" size has breaking strength of 17780 lbs which is competitive with 3/8" 1x19 and sufficient for our rig.

    Anybody out there with experience replacing 1x19 with 7x19? how'd it go?

    7x7 galvanized is probably better for standing rigging. Try Washington Chain in Seattle. They are a pretty good source and reasonably priced. http://www.wachain.com/ They don't have much of an online catalog so I would suggest a phone call or e-mail inquiry.

    Good luck,
    Don

    Yea, I'd already looked into 7x7. As I recall, the problem with 7x7 is that it doesn't come close to being the same strength for its size as 1x19 or 7x19 and I need the strength. The 7x7 would have to be much bigger--and then everything else goes up in size substantially too.
