![]() I am not sure that you have it set up correctly. Apologies if you have. I am too computer illiterate to post neat drawings on the forum as I cannot work out how to do them with windows 10. So I did a sketch by hand & photographed it. Not sure if it will work. Once again apologies if I do a bad job. i went to the boat today & took a picture of a mast aligner & can post that if you do not know what I mean. It occurs to me that some may get tangles because they release all the halyard at once. The process is to release the mainsheet & the vang so that the boom can ride up. Head to wind. Then release only small amounts of halyard at a time whilst winding in the reefing line. I take the halyard one turn round the winch & only part let off the jammer so that as I winch with the other hand I let off small amounts of halyard. I know many mark the halyard but I found it better to put a piece of tape on the mast at the point where the lowest batten will end up so as it comes down I can guess where to stop letting off halyard. Also I do not have to look down at the halyard for a small mark but can be looking up at the mast at what I am doing. It helps not to have halyards with lots of stretch as well. The sail needs to stop just before the reef block on the luff touches the mast aligner, which is the important point rather than where the end of the halyard is on the cabin winch. Winch as much clew as possible in before the very last bit of halyard then finally tighten down the halyard for a nice set If you do not have a mast aligner then you can pop rivet a hoop onto the mast with a stainless steel ring hung through it. Then run the reefing line through that. Do not try to run through an ordinary loop as it will create too much friction My current main has a ball bearing 65mm block on the luff but when my new main arrives (in the next few weeks - yippee !! ) I will probably just fit friction ringsEdited by samuel - 27 December 2016 at 17:42 |

for me it's a bit different.
Single line means, to get one stage of a reef by pulling 1 line (and of course to relief the main sheet halyard). So when you pull the red line from the cockpit, you will pull the luff down too the boom and as well the car wih the 2 blocks towards the mast. It works like a pulley and pulls through the green line line the leach down also. In that way you distribute you power to both tacks directly. Apoligize my lousy English and lousy sketch ![]() ![]() |

You have lost the 2:1 advantage of the loops at the luff & leech by & created friction inside the boom with the pulleys that provide no mechanical advantage whatsoever. Your reef lines are also a little oversize.
Change to the sketch i have shown - which is the setup supplied by Hanse- & you should have no further problems |

... thanks for your comment, Sam. It was made in that way, when I took over the 301 this year. I think, I will keep the general setup, but:
- replacing the 10 mm lines by 8mm with Dyneema core (friction, when they are running through the boom - replacing the metal shackle by a soft one The main issue was not the tension I needed to reef (with the winch it works) - main issue the blocking shackle when I needed to unreef (correct in English?). Have a nice evening ! |

Mine are 7mm& 8mm ( one is different because it cut on the aligner when I overtightened it one day & had to be changed) braid on braid. I did not want dynema as I prefer a little "give" in the lines. Unlike the halyards

Sorry Martin,
I have been too ill for the last days to go outside let along out on the river. I am getting better and will do the photos soon. I am particularly frustrated because I have a new main sheet traveller system all ready to install and I just cant get out there. We had planned a Christmas eve, and a christmas day lunch on Bloto, but had to give up the plan due to the gales and my health. Perry |

In your sketch you show the end the line going from the back of the boom up to the reefing point and finishing there. If that is the case,, then by the time you are pulling in the second reef, you are pulling on a reefing cringle which is nearly a metre from the back of the boom to just a line at the back of the boom. I do not see how this tensions the leech of the sail. The line should go from the pulley up to the reefing cringle and then back to be tied around the boom (if the mainsail is loose footed), or tied of to a slider in the track on the underside of the boom. In this way , the reefing point is being pulled both downwards and out to the end of the boom. This is the way Samuel has drawn it and I use the same system.

Your sketch is the very good Selden singleline reefing systeem with a car running back- and frontwards inside the Selden boom. The only thing wrong is the leechline have to go tru the cringle and back down ,tied on the boom by a knot or on a slider in the rail on the underside of the boom. So Martin have it right. If this give to much friction you can ask your sailmaker to at a smal reefingblock on the leech of your sail and lead the reefline tru this block. This is the way they do it on bigger boats(sails) |

As I understand it the Seldon system has a track for each pair of cars. this keeps them apart & stops them twisting or clashing together. Without this they can twist & tangle as pointed out in an earlier post |
