great on downhaul but any benefit to using it for outhauls or on the front end of a Severne boom?

I have wondered if it may be good for adjustable outhauls.
I might pick some up and try it and see if there is any difference and let you know.

Might run smoother on adjustable outhauls? I was thinking it might be more benefit at the front end clamp.

Well it's stronger than cheap rope. FWIW, I don't understand cheap rope on $1000 booms.

I found it too slippery to grab
formuline that is

Works really well on rear of adjustable outhaul.

Well the way I see it something has to give when you get catapulted over the front it's either your mast or your boom or your body OR that cheap bit of rope on your $1000 boom ,it's generally long enough to temporarily tie it up to get you back where you stated from.
I use formuline threw the pullies not in the cleat. Works well.

Yeah it don't work the best on the boom head, for some reason the cleat don't grip it well enough, might be a bit too thick.

Watched a NP vid for their carbon booms , they were mentioning it as an added selling point, both ends of booms afaik.

Formuline works great on AO. ONLY thru the pulleys. Its too slippery n hard to grab to use thru the cleats.

I prefer something stiffer because formuline is a pain to get through the extension holes

New Formuline for the downhaul. Then use the now-soft-and-supply and somewhat useless old Formuline for outhaul.

Use it on my Maui boom heads for 5+ years never had a problem and still going great.

I've had a few regular outhaul rope break. As the boom bends in and out, the outhaul rope slides and wears out. Inspect and shorten, replace when too short.

Or just use formuline :D !

Only with some extensions.

Make your own aglets by rolling tape over the soft ends, then trimming with a razor blade. Mine last for years. Very easy to string the soft line through various boom ends and extensions.

It does have issues holding in some cleats. that is why I use an 8plait Double Braid Spectra/Dyneema line instead of the 12plate Formuline. The 12 plait is lower friction but the 8 plait holds better in cleats. They both outlast good polyester by quite a bit.

On a rusted out old boom I glued a piece of rubber. I use it to wrap my outhaul around, no slippage!

To stop ends fraying, cut at desired angle. Apply a drop or two of superglue. Ya done! No more threading issues.

NEVER use Formuline in the boom head. NEVER. Unless you are extremely careful and don't try to tighten it much (which in turn means, why use Formuline then?). The boom head clamp needs elasticity. When you close the clamp, you reach a point where the rope is stretched most, then after that it gets a bit released when fully closed. This means the rope NEEDS to stretch a bit, and then come back again. Formuline does not stretch (or, better: stretches under much higher tension than the usual 0.15" Marlowe Prestretch rope). Many believe this leads to a tighter clamp, but actually it puts too much tension on the head "ears" where the rope wraps around, eventually leading to breaking those. On a MauiSails boom head, with a big clamp and skinny "ears", use of Formuline brings in most cases to very quick head failure (and on the instructions sheet it's stated very clearly to use ONLY pre-stretched polyester rope). In other booms with beefier "ears" it will be the mast the best candidate for failure. But in any cases, if the rope is not "stretchy", and Formuline is not by design, something else will have to.

That's actually an extremely good point. Common sense but I hadn't thought about it, before.

I'd argue that using too-static line in the boom clamp would actually lead to a looser lock because, as the rope gets closer to perfectly static, the cam-action of the clamp would require a longer length of line to allow it to close without crushing the mast or snapping something else and, by definition, the static rope wouldn't contract again as the clamp passes the tightest point of the cam and closes completely.

Spot on. If the line doesn't stretch elastically, either you get a loose lock, or you end up breaking something.

Another more regularly used alternative is to use a lighter to melt the end. Then as soon as it turns liquid, get your bro/mate to roll it smooth for you (so you don't burn your fingers).

NP and Streamlined booms use formuline.

Sorry bud but you can let go of the old fellow now, never had a problem using formuline on my maui boom heads, you mustn't pull it too hard.

Not true. Boom heads have a nice soft rubber - which provides good-grip and it compresses enough.
