Streamlined Boom chewing up my outhaul rope

As the outhaul rope goes through the sail eyelet there's an angle at which it comes out of the clew holes. This cut through the outhaul line.

I was thinking about filing the sharp edge of the holes so that they are rounded and don't cut into the rope.

Anybody else with this issue?

cant see that rounding the holes would do any harm. By hand with a file.

How long is and how much does out haul line cost otherwise ?

It chews it up really fast like a few sessions.

ok

It does not sound like its normal. Call Streamlined or email them

I did.

Also, do these have a tendency to slide down?
I have tightened the straps quite a bit and now it seems ok.
I dislike having to tighten the head so much, there's little friction area on these so I guess it's the only choice.

I haven't had a slidey boom is a long time, I hope it doesn't turn into one or else I'm fitting a Maui Sails head on it!

The question that comes to mind is whether you rig your outhaul using a negative component. This would permit the sail clew to move about. Is the wear on the sail side?

I've not had this problem, and i've been using the Streamlined booms for three years now. I've never had to change the outhaul rope, and I sail ~125-150 sesh/year. I do use dyneema line for the outhaul rope. The newer Streamlined booms come with this line standard, and it is very abrasion resistant.

If you have the older boom w/ the black straps on the front end, they have to be adjusted very precisely, so they're tight enough to prevent slipping. I also have used some thin shims between the straps and the urethane to micro adjust the tension.

Of course, the new boom head that uses dyneema line is much easier to adjust to correct tension and has a larger sweet spot. I have one setting on my booms that works across a variety of sizes and brands of masts. The new head is also easy to adjust if you have a mast that is an outlier.

looks like an improvement on the in haul. those black straps, used prior, would slip and fray.

dynema lines are also called formuline. if you file the exit holes, make sure you do so with a very subtle hand. looks like that part has little room for error.

you may wish to put a slight bead of a thin resin along the edge that is cutting your out haul too.
