Better yet, this article (and many other fine technical articles) are on the C380IA website....

A nicely organized resource for us also!!!!

Irv, The pulley idea originally came from a Mainsheet article in the C380 tech section a year or two ago. If you have the back issues, you should be able to find it. You rig the 320 reefing system excatly the same way. Works great. Walter Selkie #887 Irv Grunes <igrunes at comcast.net> wrote: Stan, Thanks for the reply. Again yours is an elegant solution and the fact that everything is run through pulleys elimintes a lot of the friction. If one would do the same to the leech luff, theneverything would be throgh pulleys. Thats just a thought. Did you do anything to the mainsail to protect it from any chafe by the block working against it? When the sail is down and furled, that block must just sit there and not bother the sail cover. As you can see I am trying to visualise any and all problems. I realised that it will be necessary to change the reeving on the mast base blocks so that the existing 
block will be the last block before the line goes into the boom.

The block stays with/at the same level (well, maybe a couple inches below at most) as the reefing cringle it replaced because the little line that passes through the cringle/gromett is only long enough for attachment. When reefed the block would end up in the boom area but since it is being pulled down by the block at the mast base that's fine. My addition did involve switching a couple block leads around. I'm assuming as did a couple other posters that you already have a single line reefing standard on your 
boat --- I did *-- I just wanted to reduce the friction of the line passing through the reefing cringle by - replacing - it with a block = less friction. No... I don't remember the block I used. Many of my projects are simply find what looks right and make it work. Stan >>> igrunes at comcast.net 6/7/2006 12:48 PM >>> Thank you Stan. I think its a very elegant way to mount that block. If you can remember the block you used it would be appreciated. Also, with the sail fully raised about where did the block finally rest? Did the block rest on the sail or was it at or just above the boom? How did you keep the block from flopping around or did the fact that the reefing line was through the block, it kept it from flopping too much. If I picture it correctly, there is about two feet from the sail tack to the luff reefing cringle, then you would only need to have that two feet to pull it down. I assume there was enough room below 
the boom to pull it down. Thanks for the reply.

I used a large SS washer (too big to pass through the grommet) with a small hole on one side attached to a small block on the other side of the sail grommet. I passed a small line (about 3/16) through the washer, then through the grommet, then through the body of the block, then back through the grommet, back through the washer, and then tied the two ends together with a big enough knot to keep it from passing through the washer. Not very elegant, but by 
not using any sharp metal objects for connections it didn't damage the sail and did the job. Stan (formerly) Christy Leigh c320 #656 Wickford/Narragansett Bay RI >>> igrunes at comcast.net 6/7/2006 11:17 AM >>> Guys, There was a thread a year or so back about single line reefing. I just sent the following to my boat partner. Is there any album that shows what people used for the luff pulley described below and has anyone actually done this?. I don't remember it right now, but there is supposed to be a way to make reefing a single line control by addig a pulley to the main luff reefing cringle. Then reeving the port side reefing line from the cockpit stopper to the deck mast pulley(where it now is), up through the new luff reefing pulley, down to a new mast base pulley, into the boom then to the leech cringle as we now have it, then to tie off at the boom. The key being a pulley on a strap of some kind 
on the luff reefing cringle. The main objection to this as I remember it, was all of the resistance that is encountered by the lines going through all of the pulleys. This would eliminate the need to go on deck in possible bad weather to reef the main. Irv Grunes Isle of Wight #851 __________________________________________________ Do You Yahoo!? Tired of spam?
