Single line reefing

Oct 30, 2019

Matt Rutherford's talk has persuaded us to install single line reefing but
it wasn't the occasion to get him to draw diagrams or describe the
specifics. Does anyone have this set up? Could I see pictures? What size
winches are required and where should they be mounted? Any other advice?
Many thanks in advance. Tom

I converted to two single line reefs also. The system works very well, but I am dissapointed with the amount of friction in all the routing of the lines. A main task I have now is to reduce the friction in the mainsail and main reefs because it is just a chore to get it up and down. And I am a lazy bugger.

I find I will pop out that foresail in a heartbeat. lol. But not the main.

Goiot company in france, makes a cringle block. I love it but you cant seem to contact them, and they are like $50 each I think.

Many thanks to David, Peter and Groundhog for all the information. I will
let you know how the modifications go.

Does anyone have views on how valuable it is to be able to reef from the
cockpit? I can see the single line reefing will speed up the reefing even
if it is done at the mast, getting round the fact that there is no
gooseneck hook. (I had been thinking about getting a gooseneck hook welded
on during fitting out this year.) But I can also see that to work from the
cockpit you have to be able to operate the main halyard from the cockpit
too. Looks as if that will involve two coachroof winches, or is there a way
round that which I haven't thought of.

While I am on the subject, I am also thinking seriously about a fully
battened main sail. Is it worth the extra cost?

I don't have any experience with single line reefing; however, I converted to slab/jiffy reefing a couple years ago and love it. There are still 2 lines per reef (clew and tack), but little friction and I can pop a reef in and out in under a minute (unless I have a beer in one hand). I also ran the lines aft, so there is the potential for more friction...but it has not materialized.

I'm happy to talk about the setup and could take some photos if you are interested. I have heard from others with single-line reefing about the added friction. But the Vega is small enough that I would think it would be possible to set up without too much friction.

Best of luck!

When you decide you are going to put in a reef, and if you are able to head the boat into the wind, then there is no need for a winch to pull in the reef. Without wind in the sail it has little weight.
I use a single line system very similar to those described, and I use it from the cockpit. The main halyard is secured by a rope clutch at the aft of the cabin top. I did add a cam cleat a few inches behind the main halyard winch, and I put a bit of whipping on the main halyard at each location where the halyard would be locked in the cam cleat when the reef was pulled in. In this case the halyard has three marks, one for each reef.

The routine is;
1) Pull enough slack out of the sheet/halyard bag to put the relevant mark in the cam cleat. There will be slack between the winch and the cleat. This hangs loose in the companionway.
2) Lift the lever on the rope clutch that locks the reef line, and make a mental note as to which line you will be reaching for.
2) Set up the topping lift so that it takes the weight off the leech, 18" or so. This helps reduce the friction through the leech cringle.
3)Come about and blow the jib sheet so that the boat, when she crosses the eye of the wind, will hang for a second before she falls off with any force. This is just to give you a bit more time.
4)With the boat in the eye, blow the main halyard and haul on the reefing line. When the reefing line has gathered the clew ring to the boom - lock it down. The sail, without any pressure from the wind, will drop until it is caught by the cam cleat.
5) Lock the main halyard and bring in the new jib sheet.

The boat is now reefed and you can make adjustments with some leisure. The slack in the other reef lines will need to be gathered in. Ease the topping lift. It will probably be necessary to adjust the halyard.

I like the system but it does have downsides. The extra line on deck sometimes jams in the blocks, and it would be a good idea to check they are clear before reefing. I have not found a good way to hang the blocks from the luff cringles. I use "S" hooks and they chafe the sail. I will need to sew in leather patches I think. The weight of the lines cause the leech to curl in light air. I removed the third line to alleviate that a bit (as a harbor sailor I doubt I will ever need the third reef)
A winch may be necessary if it were not possible to face the wind, because of seas perhaps, but I can't speak to that as I haven't tried it, and I don't think it would work on the first reef because top batten would catch in the crosstree. Just coming to dock downwind the batten has to be below them. The second reef perhaps, and then it may be possible to bring the reef line across the cabin to the jib winch.

Thanks Craig for such a clear and detailed explanation. I get it all except
I cannot picture where your main halyard winch is? It sounds as if you can
raise, lower and tension the main halyard from the cockpit.

I am interested in your idea of doing away with the third reef. I
completely see the advantage of having only two reefing lines, but as I
think someone else said in this thread, one should be almost as small as a
trisail. (Trysail?), and my whole motivation for considering easier reefing
is the potential for an unpredicted F9 in the Med. So I was thinking of
keeping the 3rd reef and replacing the first and second with one roughly
half way between or closer to second. Any have any thoughts on this? Just
writing that makes me doubt its wisdom.

Tom, There is a picture in the photo section, in Tern's album, of the arrangement. The reefing system was installed by the previous owner.
The winches are mounted on the coach roof next to the companionway, main to starboard, jib to port. I have thought of moving the jib winch back to the mast which would make sail changes more efficient but I also want to be able to release the jib quickly in the harbor, so will probably leave it where it is.
I had meant to say that I lock down the reefing line when the main tack ring reaches the gooseneck. Sometimes it is necessary to reach up and tug with one hand on the line as it runs along the boom to pull the leach down to the boom, while pulling the line through the rope clutch with the other.
The whipping on the halyard indicates which reef it corresponds to; one ring for the first and two for the second . . . and had I thought ahead I would have made the whipping the same color as its reef line.
If out for more than a little while it is probably worth putting a sail tie through the leech cringle and around the boom but I've never tied in the reef points, though I understand that spray and rain will fill the folds.
Too much sail falling at one time may be awkward to deal with in the wind so I think I would leave the three reefs alone, and I would put the third line back if I were going offshore. There are reefing horns that can be bolted to the gooseneck. Mine is left in place as a back up should something fail with the single line.
With a little practice reefing this way is quick and fun, and because I can do it in comfort I tend to reef earlier than most, though perhaps that says more about me than the system.
