Backstay Adjuster...

Hey, All. My boat came with a Navtec hydraulic backstay adjuster. Not really into bending the mast for optimum sailing, yet, but when I pulled the mast, the Navtec started leaking. I couldn't find much newer information on getting it rebuilt, as the company is out of business. Anyways, I came across a place, Florida Rigging and Hydraulics, in Riviera Beach, Fl. Called them up and they said yes, we rebuild them. I drove down there from Cocoa and dropped it off and they had it ready in 36 hrs for 330 bucks. Not bad, I think. I coulda put a chain and turnbuckle on it, but, heck. So, In case anybody needs a rebuild, here is the place, in Florida. You can also mail it to them. I thought somebody could use this info. Kevin

Re: Backstay Adjuster...

I agree. We can go turnbuckle with the next leak. I may need the adjuster when I enter the Americas Cup next time around, or the Volvo Ocean Race. I'm gonna make a cover for it, out of sunbrella, maybe that'll keep the heat off, a little. I believe my Navtec is about 6 or 7 yrs old. Not really sure. PO said he put it on. Kevin

Re: Backstay Adjuster...

A small umbrella/shield with tape or something else zip-tied on the rod just above the top seal...might be worthy.
I dunno...
That top seal gets the UVs.

Re: Backstay Adjuster...

A short piece of split tubing...loose on the rod...might be the simplest thing...

Re: Backstay Adjuster...

That's what failed on mine, top seal. It was fine until I took the tension off to pull the mast. Then it just started leaking. Leaked for the 3 months I was in the yard. Wouldn't hold tension for more than 2 days after mast reinstalled. I bled it and put oil in it, just wouldn't take. I'm glad I got it rebuilt. Now I can see how long it will last. kev

Re: Backstay Adjuster...

Been told itís a good idea to leave a wee bit of tension on the hydraulic backstay when you leave the boat. Just a stroke or two. Told it decreases the risk of leaks. Wonder if anyone can comment on the truth of that?

Re: Backstay Adjuster...

On your boat, backstay adjustment just reduces headstay sag... if you frequently sail in similar conditions (first I am jealous) then you probably would be better served with a turnbuckle. Given that it now works though, I'd play with how much tension you use to see how well your point improves (or does not) depending on wind speed and sea state. Inducing sag will power you up pretty significantly, but sometimes at the price of point. Its a balance.
