How do I lace this old Hawaiian Proline Boom?

Hi I've got an old Hawaiian pro line carbon boom and I'm setting up an adjustable outhaul on it.
If I want just one loop of rope through the clew eyelet its pretty obvious how to set it up. Also, if I use all 4 pulleys on the boom end its pretty obvious - but this does result in 3 loops of rope through the clew eyelet which tends to choke up on itself.

How do I lace it for just two loops of rope through the eyelet? I've come up with the following (see pics below):

Up the right side of the boom, through the lower opening an around BOTH pulleys on the underside, then out and through the clew grommet coming from the left side. Now around the upper pulley on the right side and back out, then through the clew coming from the right. Now around the top pulley and back down the left side of the boom. You'll have two loops offering 4:1 purchase. The only disadvantage is that the lines are headed in opposite directions coming through the grommet. If you just add a clew block such as the one below that problem goes away also and it's much faster to rig, too.
isthmussailboards.com/chinook-double-sail-pulley-outhaul.html

With the clew block you'd come up the right side, through the UPPER pulley first, then (around clew block and) now go through the lower pulley on the right and around both, coming out on the left side then around left side of block, back through upper pulley on the left and down left side of boom.

It's identical to the old Fiberspar boom end.

Get a Chinook outhaul pulley for the sail, one loop goes around each side, perfect for an adjustable outhaul setup. I have one for each sail so I do not need to remove them.

The pulley for the outhaul by Severne is much better than those bulky ones from chinook.

Not sure about one being more bulky than the other, but the Chinook pulley is tool-less, just turn with fingers to tighten or loosen.

If you have a wide tail on your boom, the Chinook pulley is fine. However, with a normal narrow tail I used to catch my side forward running lines on the Chinook pulley when the outhaul was released for downwind. In that situation the lower-bulk Severne would have been better.

Some sails such as Maui Sails race sails had the pulley fitting built in to the sail. That was the best.

If, however, you have a sail with a grommet in the clew (most sails nowadays), either use the Chinook or Severne pulley or, better yet, use the Sailworks-style of adjustable outhaul. You have to get 8:1 multiplication overall. With the pulley you could use a single 2:1 multiplication on the boom arms. With a grommet, you have to use 2:1 x 2:1 on the boom arms, which the Sailworks AO provides.

I have personal experience with both and I have now replaced all the Chinooks with Severnes. Severn is a tighten and forget solution that keeps the line in place. The chinook takes up more space and the bolt sticks out, catching and damaging both the lines and boom. The smaller lines (around 3-4mm if I remember correctly) will also fall out of the pulleys if the sail is put down into the water etc etc.

Or have one side annoyingly pop out when you slacken the outhaul and have to pump a bit in light air.

Thanks all, I don't have a clew block - could I temporarily just use an old downhaul pulley or will that just fall out of the grommet?

Hey Troy ,buy one or two from surf & sail ,also known as a apple core ,last time I brought them they where 22 $

i did use a downhaul pulley once but it kept dropping off ,but it does work ,but you will have to add extra on the boom
which does make it floppy ,so not that good .

the apple cores have little lugs that hold the rope in place ,and the string never drops out

you will love your outhaul system once you get use to it .

I use chinook's but I want to try this one:

lisawindsurfing.com/#twist-lock-pulley




It stays with the boom and seems the fastest to attach. And it wouldn't be possible for the rope to get out on low tension setting (it has happened to me with chinook's)

Agree SurferKris, the screw sticking out is a problem, I used a dremel to cut it almost flush with the outside of the pulley, and a file to round off the one turn of exposed threads. That was done with the pulley assembled, so when it was disassembled the nut cleaned up the cut/filed threads. Never had a line fall out of the pulley, but have caught the AO line on pulley while rigging like segler said, but that happen when the sail clew was too far away from the boom tail, if clew is almost touching the boom tail not a problem, but now always check to make sure AO lines are not caught in Chinook pulley before outhauling.

Yeah, and did you see the price?, it is 60 euros!, for one! I have one Chinook pulley at $10 each on every sail, times 5 sails is $50.

I've got one and it works fine on my cammed sails . The Gators have more ribbing around the clew which makes it a pain to clip it through. Once it's done though it works great.

I use those on my freeride sails but I take them out before rolling the sail to avoid damaging the sails.

Damaging the sails due to the protruding screw?, I trimmed them all down, see above, and leave the Chinook pulley in every sail and never remove them, very convenient. I have not seen any sail damage from the pulleys with the flush screws.

But you only need one per boom. Plus, if you have two clew rings, you can pick either. Mine was delivered three days ago. I'll report back after using it.

With one per boom you have to remove from sail and place on next sail you use, when leaving Chinook pulley on the sail it is Set it and forget it! And if I want to put on a different clew grommet, the Chinook unscrews without a tool in maybe 15 seconds with a trimmed screw that is flush with outside of pulley. But to date, I have only used the upper clew grommet on all my sails, but that may change now that I know the lower clew grommet will depower the sail.

The idea that you can just leave the Lisa pulley on the boom AO lines and attach to sails does not seem possible to me because if I use a larger or smaller sail I need to adjust the outhaul lines and boom tail, so I think I would need to remove the Lisa pulley from the AO lines first, before adjusting boom for a sail, then mount the boom on the mast and sail, and then reinsert the pulley onto AO lines and sail clew. A lot of removing and reassembling for every different size sail. And if you only use one sail then it would be more user friendly, but still 60 euros?!

You definitely don't know how the system works. its possible to leave the Lisa pulley on the boom; also you don't need to anything to it when adjusting the boom length for different sail sizes. I hope this helps:




I have been using an avanti pulley prototype that uses the same idea (instead of "twist lock" it has the same system as a ratchet to keep a socket in place) and I really like it.

Willywind, you are right I do not know how to use it when rigging a sail, and after watching the video I still do not know how BECAUSE the video did not show a sail being rigged with the pulley! But the video did show me that there are flexible plastic parts that can/will break over time and that there are lots of places for sand to get into. The Chinook pulley follows the KISS rule! But thank you for posting the video, was thinking it would be interesting to have one to try, but will now stick with the simple and durable Chinook pulley.

How do I lace it for just two loops of rope through the eyelet? I've come up with the following (see pics below):



How will you derig this set up? You will need to detach one of the adj out haul ropes. I don't think that its meant to work going thru clew eyelet AND having adj OH. Get the Chinook pulley and just loop over and use the 3 pulleys which will make adjustment on the fly easier that trying to pull against binding rope in the eyelet.

Wow, thanks SurferKris Severne is a lot smaller!, will have to get my hands on one to check out, but widthwise I think they "will" be closer than in your picture when on my sails, because the SS grommets will make the Severne wider. The two tapered plastic pieces on the inside of Chinook nest inside the grommet space from what I can tell. I never remove the pulley, have one on each sail, so the fact that the Severne requires a tool is not an issue for me.

But Chinook work fine for me, though you definitely need to cut and file the screw, that screw will bang into the inside of the boom tail, and on my carbon tail was scratching it, that is why I trimmed the screws down, and they could also damage sail when you roll it up like sboardcrazy mentioned, before I trimmed the screw I was careful to roll the sail up with the screw end facing outward in the rolled sail.
