"marrying" blocks


hamilton

Recommended Posts

I'm not sure this is the right term for it - and I don't recommend taking it literally - but I'm wondering if anyone could share an effective technique for rigging two blocks together - as in a larger and smaller block stropped or seized together at a yard arm for the sheets/lifts or (in my case) on the bowsprit for the jib stay (the larger) and the jib downhaul (the smaller)...

 

Anyway, any and all advice is appreciated! Sorry for so many questions today!

Hi Hamilton.

In my below suggestion (this is what I do…) you will need at least one false (zip) seizing.

You seize one block at the end of a thread (a), you make a cow hitch knot (d), through which you pass the bowsprit,

you make a loop and adjust the false seizing (b.) and the second block.

By pulling the free end of the thread (c.) you bring together the two blocks while you fasten them on the bowsprit.

You finish with a drop of glue at the false seizing.

Thanks

My two cents: I’m not familiar with what ship your working on but I can point out the nature of a downhaul on a staysail, a line running from the head of the staysail down along the stay back to the bowsprit or jiboom, used to pull the sail down to the spar in order to strike it. The canvas of the sail itself necessitates the block in question to be on one side or the other of the centerline of the spar, since the line would have to run down one side or the other of the sail, along the luff. So your downhaul block should be near to but not directly aft of wherever the stay terminates on the spar. If the downhaul block was on the centerline of the spar and/or immediately aft of the block for the stay, the canvas of the sail, as it was being struck, would quickly smother the block. folds of canvas would get in the way while the downhaul was being used, and the downhaul  would chafe away at the sail. I would recommend locating your downhaul block at about a 3:30 or 7:45 position in relation to wherever your stay leads to in the headrig, or at any rate whichever point is under the tack of the sail as it is struck.

Thanks Frankie - I'll have to revisit the rigging plan to see if there's anything amiss with what I've already done - but this makes sense. Thanks again
