I had the opportunity yesterday to assist in dropping the swing keel on (Carry - Ann) a 1981 C25. This was the second opportunity for me on this task this year, both boats were 1981 C25 SK’s. And Boy what a difference. Mine (Two Port Feet) having five plus, prior owners lived a rough an hard salt water life, until Me of cores. When we repaired mine I felt relived the keel was still on. 75% of the keel pin had been worn through as in gone, not there. On the keel it self the pin hole was enlarged so bad the hole aria need rebuilding. Carry-Ann on the other hand had only one owner, saw only fresh lake water, and was hulled out each winter to rest on her trailer in a covered shed. When we dropped the keel an pulled the pin It was hard to believe but it looked just like new. So we cleaned her up greased the pin , put a little lock tite on the four bolts and then bolted her back together. After a bottom job she looked just like new. Both boats are sailed a lot. Not bad for a twenty nine year old boats and still going strong. Got to love those Catalina 25’s.

I sail on an inland lake in Kansas and it is fun to buy used boats here because all you usually need to do is clean'm and sail'm. A freshwater boat with a winter trailer is a pampered boat for sure.

Pearl spends summers in fresh and winters in salt, and she eats zincs pretty aggressively in the winter.

Dave,
Odd you should say your boat eats zincs in saltwater. Passage has never needed a replacement zinc in the past four years. I have one zinc on the outboard and one on the keel.

Do you plug your boat into shore power in FL? If so, you probably have a problem with stray currents, bonding your DC ground to the green wire on the AC circuit. I don't use shore power, and have not connected the AC and DC circuits on Passage, and so haven't had the problem.

November's SAIL magazine, however, has an awesome article about installing a galvanic isolator to prevent this problem. The article is crystal clear about doing it yourself.

If you don't have access to the magazine, I can scan it and email it to you - let me know on bruce 2 sail at aol dot com.

You also have a lead keel. The weather is to cold when I haul out in late fall for me to touchup the epoxy finish on my keel, so there is always some exposed iron until I haul out and address it in the spring. The galvanic isolator won't help me, and replacing the zincs on the keel is just a matter of 2 screws on each zinc every 2-3 years. I don't have a bonded system, so the zincs only protect my iron paperweight.

You can see what I "assumed", which was dead wrong. Two zincs and five minutes to replace them is certainly cheap insurance!

And, by the way, I would love to be able to head south for the winter -- I'm jealous actually!
How's about scoutin' a place when you get down there. There's gotta be a bargain 2000 sf ranch on waterfront with a dock on a bay somewhere in FLA!

Ok, I’m jumping in with dumb embarrassment. I have a 1980 fin keel – which means iron not lead, exposed not encapsulated. I have NEVER replaced zinc. In fact the only one zinc i know of is on the engine, which has electric start and alternator to charge the two batteries. Are their symptoms I should be looking for (like disappearing keel bolts) that would indicate that “Houston, we have a problem . . . .”?

Sorta close to the paper mill.. But I'd bet the mill will shut down before long, if not already.

$500,000 and comes with a sailboat.

I searched that site and found stuff from $10,000,000 right down to $55,000. But your definition of waterfront and mine may differ.

Yepper.. I kinda know the area so I was only looking at stuff that could get to the gulf fast with deep water. It really is kinda limited and expensive.

Peter, do you haul out in the winter? The damage caused by stray current will corrode metal in the water. Any significant corrosion on the keel when you haul?

Are you in a marina or on a mooring? If the latter, the chances of stray current in the water are significantly lessened I'd imagine.

Peter,
As I recall you're on a salt water mooring in Long Island Sound, so chances are slim your keel is getting attacked by shore power stray currents (unless you've got a really long extension cord!).

Is your keel completely exposed (like rust), or is it encapsulated with a coating of fibreglass or barrier coat? (bottom paint doesn't count).

Like most people, you have a 12V DC system (engine, battery, etc). Are the keel bolts grounded to the electrical panel or battery? If so, there is a possibility that the engine and keel could set up some galvanic action while the engine is running. But your engine zinc would probably indicate a problem like the coalminer's canary.

Visually, when you pulled Limerick in the fall, did you see any signs of corrosion on the surface of the keel, or on the keel bolts in the bilge?

And while this next suggestion is strictly against my 'religion' (if it works don't fix it), you could put a huge socket wrench on your keel bolt nuts and give them a spin to see whether they are ready to snap off. Like I said, if it works....

You could also "sister" the your keel bolts. There were a few threads on that topic recently.

But as I said, my guess is it's not a major problem. Scary thought however

If you do haul out in the fall, it doesn't take long to drill and tap the keel for zincs.

Lets see: Yes, I am on a mooring far from any dock. No, I do not have coating other than ablative bottom paint. As the bottom appears related to the moon surface, powder blasting and barrier coating are on the mid-to-long term list of "to do's. The zinc on the engine looks fine -- after four seasons. And the keel bolts have been "rusted in place" since I bought her. My surveyor said they are tight and "don't mess with them".

This thread has me curious if the zinc on the engine is replaced as "routine" (I'd be shocked if yes) and makes me want to move forward the project of powder blasting/barrier coat - and add a zinc to the keel. And yet, if it ain't broke . . . .

And . . . every fall when the boat is hauled and cleaned others have told me the bottom looks really good for a 30+ year old hull . . . . .

Peter, your engine is in no danger--it lives up in the air (I presume). You are on a mooring far from any stray currents--the closest would be at the Wilson Cove Marina which is how far from you?? IMHO, you're very safe!

I kinda figured that as I have seen no indication of electolosis that all was ok -- but reading of others experiences makes one ponder. As for relative location, I am as far from Wilson Cove Marina as possible (as well As Norwalk YC & RYCHB) with my mooring toward the mouth right next to Belle Island. I motored on/off the mooring only twice during the season!

Stray current is much less of an issue in salt water than fresh, simply because salt water conducts it away (thereby dissipating it) so much more readily. In fresh water, people are electrocuted or drown from being paralyzed by stray current when swimming near or in a marina, but rarely if ever in salt water. Wiring faults in aluminum boats are often the cause.

Peter, I was just looking at your mooring field on GeoGarage (http://marine.geogarage.com/routes/). Where do you launch your dinghy? At the marina up at the end of the Cove on Wilson Ave?

Bruce, excellent site. In Wilson Cove their are three "clubs" -- Wilson Pt. Yacht Club (and marina) is the farthest in on Wilson Ave. Norwalk Yacht Club is on Wilson Point (Nathan Hale Road seen on the right side). I am located at Rowayton Yacht Club, which is located on Bluff Ave near the bridge that becomes Westmere Ave. RYC has a launch ramp which is used in fall/spring or by special request. Dingy's/kayaks, etc, can be launched from the beach. That said, I do not have a dingy but use the club's launch service. Limerick is moored off of Belle Island. If you see Brown place (on Belle Island off of Westmere) -- and go straight out into Wilson Cove,thats where we are located. It would appear (from some snooping around looking at area construction, etc) that the image was taken 7-10 days before labor Day. Looking at the tightest magnification I think I can make out which boat is mine, but am not quite sure as my neighbors include an Oday 272 and Pearson 26. I believe Limerick is the first boat to the right of the work float, which is next to the point where the house and pool are.

More recent Dave; as I moved the curser around town I saw the construction of the houses being built behind mine -- which commenced in early August and is just about complete now -- based on the pics (and the fact that Tok still had swimming floats in and I did not see my son's car at NYC) I estimate late August. All the satellite sites like these are, on one hand, kinda neat, but on the other a bit concerning as they are too reminiscent of Orwell's "1984". Oh well . . .

Apparently the images for Google Earth etc. are of various vintages. I've been wishing they'd update my area.

The photo of Passage at Brewers Stratford would definitely show a person on deck, or in the swimming pool in the yard. I'm trying to determine whether one of the cars parked at the southernmost dock is my Jeep. Kinda washed out photo.

Just an FYI for most of you out there - they now recommend magnesium annodes for fresh water boats.
