single line reefing - big stresses

[Stemar]

I would love to see some pix of these reefing systems

it seems that it should be possible to make it work provided I invest in enough good blocks and put them in the right place

Sorry, no pix until spring as Jissel's on the hard with the mast down, and I don't do photobucket or whatever, so may not be able to do public photos then. I'll be happy to email some photos once she's back in commission, but I'll have forgotten by then, so nag me with a PM in early April if you're still interested. If you want to come and have a look and a play, you'd be very welcome.

When used properly I've never had issues. What does often cause extra stress is not using the topping lift while reefing, so the reefing line often has to lift the boom at the same time. This also causes the clew to tighten first, which makes it almost impossible to then successfully tighten the tack without having major issues.

Well............I never thought in 30 years of sailing of that so thanks. I look forward to trying this next season.

Had single line on the last boat and hated it.
It was a dog to pull reefs in and a pig to shake reefs out. If you want to reef from the cockpit, have a simple twin line system one of the luff one for the leech. A few more lines but much more effective.
When using the single line I used to make off the luff off on the reefing horns because otherwise I couldn't get good luff tension due to stretch on the miles of internal lines.
Dyneema may be the answer but....what was the question!!

At least you will be able to see it and fix it if/when it jams. I converted my roller reefing to slab reefing by rivetting pulleys and cleats to the outside of the boom. It was cheap and works. I only reef the clew, though - the tack hooks onto rams horns.

The 1st single-line reef, on the outside of my boom goes in a treat, the second, that goes over a couple of pulleys in side the boom is a pig.

The secret is to use ball-bearing (not plain bearing) pulleys - as large a diameter as you can get and as thin a line nas you can grip - hence Dyneema.

I reckon you should rig it like mine then

Can only do two reefs as the rectangular-section boom only has two sides. But that ought to be plenty for KTL purposes, right?
