Dynex to rope splice for halyards

[Brion Toss]

Hi there,
Glad your research bore fruit. I agree with your sailmaker that halyard loads are 75% (or a bit more) of sheet loads. Remember, though, that sheet loads are relative to apparent windspeed. Also note that safety factor is just one consideration for halyards; keeping the load down means less stretch, and that means better performance and less chafe. And for sustained loads, like a jib furler halyard, creep can be an issue, so try to make the moderate-conditions design load 15% or less of break strength.
Fair leads,
