Genoa Halyard Replacement?

[Jeffrey Hare]

Hello,

Our rigger commented that our Genoa Halyard was really a larger diameter than required, causing some extra drag hoisting and dropping the genoa on top of being "a bit too stretchy".

Because we were having issues with the top genoa swivel not swiveling and causing the halyard to wrap at the top, we added a Selden fairlead just below the exit block for the halyard and at the same time replaced the swivel.  ($ouch$).  That ensured that there was enough angle to the top swivel when the sail was fully hoisted that it won't wrap.

I think the manual calls for 100' of 1/2" line and I'm curious what others might be using here instead of that 1/2" Yale Braid that comes stock.  Is 7/16" (11mm) reasonable or can I go with 10mm and still have the rope clutches work?

With all that said, does anyone have any tips you've discovered for greasing the genoa and main furlers?  

Thanks everyone.

Hi Jeff,

 My boat #77 has older Lewmar clutches. They are marked inside with ’12’ or ’10’ which I suppose means 12mm or 10mm. I have 10 mm line for the outhaul and vang which are in a ’12’ clutch with no slippage.

Ok, so the 12 10 is probably the line diameter range from 12-10mm.  So, 11 would be right in the middle.  So, I suppose I could use a 10mm (maybe a line with a more high tech core) would let the line run a bit easier and still be both strong enough and work in the clutch.

Thanks,  I now know what to look for.

Hi Jeff,

I like the carpet too.

For greasing the Selden furlers I would refer to the appropriate Selden support manuals. 

https://support.seldenmast.com/en/technical_info/service_manuals.html

I've always used the Selden recommended grease 312-501.

Hope this helps

Best

Charlie

And let me add that my main halyard is 8mm dyneema and it is in a '10' clutch with no slippage. Not sure why they went with the 1/2” line instead of thinner dyneema. Cost probably.

Bill, 

I believe our main halyard is also 8mm dyneema.  I recall that Jon said he installed a different sized clutch insert that was for smaller line.  I'm guessing that the later models already came with this insert to help prevent main halyard slipping.  I want to cut off about 10" and resplice the end that connects to the head swivel of the mainsail.  That will have the line clutch gripping on a new section of the main halyard.  The section where it grips now (after 14yrs or so in the same general spot) is a bit flattened out and by taking a bit off the other end of the line, it'll have a fresh area to grip on.

But... I'm going to have to brush up on my dyneema eye splicing skills... :)
