Ah,yes, a spliced main halyard connected to the clew by a bronze/brass snap shackle. Yo ho Ho and a bottle of rum me hearties.
Er, Granny ... main halyard to clew?!?!?!? A main halyard attaches to a mainsail's head. An outhaul or a sheet attaches to a clew. Since there is no boom visible in the picture, one has to assume it is a single (of two required) sheet attached to the clew of a headsail. A bronze snap shackle has no place on the clew of a headsail - too dangerous when flogging. Bowlines are preferred. All in all, an ambiguous image; it MAY be a mainsheet on a loose-footed, and possibly boomless, main. So endeth the lesson.Cheers!(Alberg 37 owner)
I humbly stand corrected.
No need, really. Without the context of a fuller shot, no sailor would bet his rum on a definitive answer.
