That's an answer to a question never asked.

Tie a half hitch or figure 8 at the dead end. Pass through grommet, then tie a half hitch. Cinch it tight so the knot at the end acts as a stopper, preventing the line from slipping through the half itch. It will tighten even more when wet and will not become undone unless using brand new line with very low outhaul. No hardware, 3 seconds.

Shocked uooh, well I guess I was waiting on this one with baited breath....why is this better than my single spectra line pass thru the grommet to the cleat? try 1 second Exclamation ....then I can splurge on the other two secs by tying a figure 8 as a stopper in case the cleat lets go.... Rolling Eyes

as for the swivel 'n shackle, why would we add a few grams of swingweight to the end of the boom after spending hundreds to reduce weight Question plus your line is now not centered on the clew with a single lead....just sayin'

Hi Girls !

It is nice to read all these comments as I am just waking up. This is the middle-east. There is a time lag. Also, we don't have the loop and go system here.

After watching the video on the loop and go, I confirm my rigging is faster. The shackle stay permanently attached to the sail steel hole. So I just need to pull the rope through the cleat and I am done with rigging the boom end.

Everything was bought from the local hardware stuff. I am trying to have everything carbon-made to reduce weight.

I did not try tying the rope directly to the clew. I am not confortable doing knots. I am afraid it will slip. However, I did a knot to prevent the rope from slipping back trough the cleat but it does not show on the pic.

And please upload pictures. Not only is English a second language to me, but technical /maritime words are even harder to understand. Pictures will also be more fun for everyone to watch.

What is nice with windsurfing is that it allows me to explore my creative side.

Where in the ME? I've spent a fair amount of time at different spots in the region. Though only for work.

It has been working fine for a year (no loop, straightline from the sail hole through the boom end, rigging in 3 seconds), and now the boom end is worn out.

I don't think it is. Even if it is, it would be a matter of only a few seconds. The benefit of those seconds is far outweighed in my opinion by the addition of clew weight, which is the last thing I want.

I love messing around with these ideas too! Keep at it.

That boom end/cleat anchor very likely wore out (failed!) because you're running the line through the sail grommet only once. Each pass through the grommet reduces line tension dramatically; just the second pass alone cuts the pull on that cleat by about 50%. The cleat anchor wasn't designed to carry a single-pass load.

I always applaud creativity, but agree with iso on this one. The cleat probably failed because of the single clew line.

1:1 (like OP has) - full tension
2:1 (two loops) - each section carries 1/2 the total tension.
4:1 (4 loops - what most people use) - each section of line has 1/4 the total tension so cleat only has 1/4 the total force of it of OP's system, also one only has to pull with 1/4 the force of OP's system when pulling outhaul.


it's just basic high school physics, humans have known about this since the Greeks, at least.

As well, he has a 1:1 purchase - makes outhauling much harder with no mechanical advantage. Maybe not a big deal if you're strong, but if it slips out on the water it will be hard to deal with.
