Stopped by West Marine. Gotta be careful there, because sometimes they may sell you the Wrong Thing. Case in point: The Admiral and I stopped by one that's near our boat, and they were happy to sell us a Harken 2602
, which is right for our boat, and a Harken 060
, which, tho it's also a 57mm (fiddle) block, is undersized for our application. Harken recommends, for our needs, a 1566
. The critical difference being an 1800 lb. safe working load, vs. 500, and a breaking strength of 5000 lbs, vs 2000.
And I forgot the "Viagra" for the fiddle block!
Hopefully, one of the WM's close-by, or maybe Mike's, will have the fiddle block we need, so we can get this stuff installed this Sunday.
The cordage is actually in fine shape, and of the right size (3/8").
Re: Cordage too large. Could be. Could be the original cordage was 5/16", rather than the 3/8" that's on there now.
Yes, others have mentioned the load issue. I'll make sure to double-check the attachment point on the boom. Thanks for the heads-up.
Problem is, the blocks we're looking at won't all take 1/2" cordage. The double that's going on the boom, if we stick with the Harken we now have in-hand, takes a max of 7/16". The Harken fiddle block they
say we need will take up to 9/16". The Lewmar fiddle blocks Alex recommended I think
were max 3/8". We have what appears to be 3/8" on the boat, now, and it's in good condition. I think we'll give that a go with new blocks before looking to replace that.
Thanks, everbody, for your comments.
