I'm going to change the lifting cable and turning the ball and was thinking about the Keel Eyebolt. We've got the new retrofit model, upon visual inspection it looks fine...but how do you really know

Jerry,

You don't really know short of backing the mounting bolt and counting the number of turns still working in the keel. My '83 swing lost its purchase and dropped the keel...I had to re drill the hole and tap to its new depth and hope that that would serve my purposes. But by this time I had had it with the swing and at the next opportunity I retrofitted to the wing.

Val,
Didn't the dropping do some serous damage to the keel trunk? Given my experiences in general w/ these type of renovation projects, I'm in the mode of 'if it's not broke, don't fix it'...which of course is a short sighted position...

Jerry, did you do the retro fit yourself?

Jerry,


It's been my experience that dropping the swing unimpeded will cause considerable damage, which it did. I had it repaired once and when it resurfaced I decided that I had had enough and changed over to the wing. Lotsa money but the best that I ever spent on the boat.

Unless you have to raise the keel due to shallow water, haul-outs, etc., don't. Leave it in the full down position with just enough turns on the winch to take the slack out of the cable.

Read the many, many threads in the archives about this issue, so we won't rehash it yet one more time.

It doesn't take much unimpeded swing to crack the keel trunk. All I did last year was get too close to a channel marker that was the turning mark in a club race; swing keel caught on the buoy's anchor cable and must have lifted it a bit. I didn't hear or feel anything unusual given the circumstances, but it was enough lift for the drop back down to put a hairline crack in the keel trunk resulting in a 1-bucket per day leak. Cost me almost $800 to have it fixed.
As to your question Jerry, I can't speak to salt water as I'm in fresh water, and as Brooke indicated, there have been several threads on this subject. I'm sure salt water requires more frequent checks of the cable and keel bolt and probably replacement more often, as well as sacrificial zincs. The keel weighs 1500 lbs. Personally, I would leave it down and plan on replacing the cable more often. Because the keel trunk at the cable end is very shallow, the keel bolt will most likely be in the water all the time whether the keel is up or down, so the real issue is the effect of salt water on the cable.

If you have the new attachment fitting, change it. I check my cable, fittings, and pivot after recovery in the Fall from Erie and Spring from the gulf. If in doubt, and your eyebolt is probably as old as your boat, replace it.

If it isn't the case, I'll nonetheless submit that when you lift something out of salt water and don't rinse the salt off, the moisture that the salt leaches out of the air is as much of a threat as the water. If it were me, I'd leave the keel down.
