Here are Higgins' photos:

I assume I would not try to pull that down below the cars to the level of the boom, as I think that the wind would put a lot of side pressure on those ?
Yes, they're slugs, not cars. Making up a dogbone (two rings with piece of webbing between them) that goes through the cringle would help, but, yes, you would want to pull the cringle (big grommet) down to the reefing hook if you don't have a dogbone.

I have a track with pulleys at the booms end, that looks like the Harken reefing system. But there are 2 double pulleys near the front, and I have no idea what they have been used for ?
(They are NOT in line with any cringle or pulley at the mast or deck ?
Typically, if you have a single line reefing setup, you'd have blocks like that setup—and that is what they are probably intended for. You'd have the reefing line run up from the boom, to a block at the aft end of the boom, forward to the first aft-most double block, and up to a block attached to the sail at the reefing cringle, and then down to the forward most block and then aft to a cleat. You've got two cleats on the side of the boom and probably only two reefs in the mainsail.

But the forward most blocks look like they're designed to have a line come down and then go forward... not back aft to the cleats, at least from what I can see in the photo. Do the reefing lines have blocks at the base of the mast to run them back to the cockpit?? If so, that would explain it.

I'd point out that double-line reefing systems, although they require more hardware, are generally better IMHO, since they allow you better control over sail shape with less effort—since you can tension the clew and tack of the reef separately.

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.

Hi,
thanks for all the help and and explanations.
I finally decided to follow SDs hints and put a 2 line reefing in, without feeding the lines back into the cockpit. So I had a sailmaker make me 2 openings in the stack pack I had dismounted 2 years ago and put it back in. I know can lead a line from the leech reefing cringle through the stack back to the boom pulleys and cleat, and one hook from the tack cringle to the mast cleat.

Tried that (without wind ) on the weekend and it loocked fine to me
(whatever the importance of that)

Thanks again

Re: How Do You Reef the Mainsail?

Yes, exactly right.
The force of the wind has two vectors. One is to make the boat go forward the other is to tip the boat over. Once the wind is too strong the boat will tip, heel too much.
If you lower the sail to make is smaller it is still enough to make the boat move forward but it will tip less.

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Re: How Do You Reef the Mainsail?

Cool. I just bought a saroca. Havent gone out yet. My other small boat had a furl/unfurl sail. So this new one is "cat" style rigged so im trying to figure out if its all or nuthing with the sail? Or if it can be lowered and reefed?
