Hi David,



I briefly considered the loads on the attachment point for the shrouds before deciding to attach the spin blocks there . . . I’m guessing it’s a non-issue (suppose only the boat builder can tell us for sure). A component of the spin block load is definitely in a different direction than the load that would be applied by the shroud, but the spin block load isn’t all that great - my wife can trim the chute by hand (with no mechanical advantage). The load from the shroud regularly gets up in the range of the weight of two people plus half the boat (think of flying a hull while sitting in) – the attachment point has to be pretty heavily reinforced.



For attaching the blocks, I replaced the 1/4” bolt w/ locking nut that attaches the stay adjuster to the chainplate with a 1/4” bow shackle (with loc-tite on the threads). The spin block is attached to the bow shackle. I eventually plan to make a bracket for attaching cam cleats to each of the stay adjusters, so I can cleat the spin sheet temporarily. I’m thinking this would be more reliable for un-cleating compared to a block mounted cleat.



Have a good sail this weekend.
