Outhaul friction

[Brion Toss]

Hello,
Yup, a velcro collar, preferably made with Spectra webbing, is the way to go. On some booms, you might need to move reef or mainsheet hardware, but they likely don't belong in the collar's range of motion. Also, to get the most out of your outhaul, a 6: or 8:1 advantage will make it sufficiently easy to control the sail that you will actually be inclined to adjust it.
Fair leads,
Brion Toss

Hmmm. I was going to suggest simply lubricating the slug and the track if you haven't already done that. A little McLube dry lubricant can do wonders.
