Nicely done Giu and Columbia, my 26 footer is rigged the same and reefed as drawn by Giu


nice to see a topic like this for a change

1955 Blanchard 51 Custom ( I got a woody )

Lord, give me coffee to change the things I can change and Rum to accept the things I can't

Document with pictures

A few years ago I wrote a short document with lots of pictures that showed how single line reefing was done on my 1986 Newport 28.

I would be happy to send a copy if anyone wants one.

If there is a web site to post I will do that to.

Point A is a reef tack, Point D is the reef clew, and points in-between are reef points, which are mainly used to bundle up the sail so the bunt of the sail doesn't blow around or chafe.

The reef tack is usually attached to a tack hook on the goose neck of the boom. The reef clew is setup as per Giu's diagram.

On some boats, they have a set of blocks and a single line that runs from the boom, up to the reef clew, down to the end of the boom—so the line can pull the reef clew out and down at the same time—to a cheek block near the goose neck and up through the reef tack and then down to a block and back to the cockpit. This is a called single line reefing setup—because it uses a single line to reef the sail.

They also have a second line that goes from the goose neck, up to the reef tack and down to a block on the deck and back to the cockpit. This is a called double line reefing setup—because it uses a two lines to reef the sail.

IMHO, if you want to be able to reef from the cockpit, this is a better setup than the single-line reefing systems.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I can attest that Alex actually can sail properly. He knows when to use the crew to put in a reef line by walking on the boom and when to use Canadians as fenders when docking a 4 metre beam boat in a 4.01 metre slip.

Saurav - The general rule of thumb is that if you think you need to reef, reef. There's no fast rule as to the wind speed needed to reef. Reef early, reef often, and practice it. On our Passport 40, we put a mainsail reef in at 15, a genny reef in at 18 or so, a second main reef in at 22 and a second genny reef in at 25. On the other hand, a couple of days ago we were in no hurry and had a double reefed main and single reefed genny at 18-20. We sailed slow, but we sure were comfortable! We don't like being hard over if we don't have to be. It makes our sandwiches fall off the cockpit table. And our daughter gets fairly terrified if we're hard over... The worst thing to do is look around, see nobody else reefed, and feel obligated to leave all your sail out. It's all about your comfort factor and how much stuff you didn't secure in your cabin.

Well done, Giu.
I would note that all of the gear, mentioned by the Dog, is capable of being retro-fitted to virtually any boat. Harken offers two different size kits, in both single line and double line reefing, depending on the size of boat. They can be installed with a modicum of mechanical ability and a few tools. The most challenging aspect of their installation, aside from the cost, is the reinforcing of the mains'l and attaching of a steel ring to it. Perhaps, if in doubt, a sailmaker should perform that portion of the work.

And, for the record, it is a sheave and not a pulley or pully. The sheaves in this case will reside in cheek blocks, tail blocks, and perhaps a floating block. Pulleys are generally found in Erector sets or attached to the limb of an Oak tree for automobile engine removals, both lubberly pursuits. (g)

Most sails that are for larger boats come with reefing points installed.

Well said, in your snobbiest yatchly voice I might add... and you forgot foot blocks.

It seems usage kinda wanders around a bit. Strictly speaking, a sheave is just a grooved wheel. Can't to much with that 'cept roll it around on the floor . A block can refer to either the frame w/in which a sheave is mounted, or the entire assembly. Similarly: Pulley can refer to just the grooved wheel (sheave), or the entire assembly.

Interestingly enough: Of the the three books on sailing I currently have on loan from the library, each of them refer to the assemby as a "block" (most commonly) or "pulley," with only one mentioning "sheave," in passing.

So there you go.

Valiente,
What's this about the Portugese "walking on the boom"?
