I saw that stainless slug, and thought that would probably work. The only bad
thing would be that stainless rubbing up in inside of the aluminum luff track scraping off the hard coat as it goes. Personally, I have enough corrosion battles going on without inviting any more.
Then to the extreme possibilites, with stainless being harder than aluminum...after about a million cycles it's probably scrape it'd way all the way through...OK, that's BS.....
Just call me anal, I wouldn't use one. I'm rather happy with the aluminum luff track that replaced the plastic, and had I known what the hell I was doing before I changed it out, it would have been a piece of cake. Taking the mast head off and sliding the track off is
the way to go. Just make sure you drill out that #$%^&*()_*
rivet about 6" down from the top of the mast first. Use some 5 minute epoxy to reseal the mast head against leaks when you rivet it back on.
I think the ideal method, if one didn't want to replace the plastic luff track, would be to have a sail loft replace and sew in the first 6 inches or so of the bolt rope next to the headboard with a plastic dowl rod of the same diameter. Cost wise it'd still be cheaper to just change out the luff track @$30 a whack. IMHO
I think it's great, and yet odd that you've never had the pleasure of the sail pulling out like so many of the rest of us. I'm just curious as to what makes your boat different. Wait, I'm getting confused....do you have the SE??
