DaveP, thanks for the picture, mine doesn't look near that nice. The winch came Wed, I hope to replace it tomorrow (Saturday), but not sure when I'll be able to splash it (the paper towels are ready). My worry is if there is damage, it's below the floor and will require cutting the floor, but I am still optimistic (or ignorant) that I escaped without damage. If nothing else, it's making me fix the leaky thru-hull.

David- Did they have to cut away the deck liner around the keel trunk to do the fiberglass work? If not, how did they get down to where the trunk meets the hull?

I forgot to add... The reason I ask is because I am looking to do the same sort of thing and have been pondering this very question.

Thanks, I thought he did a good job. Our damage appeared to be a hairline crack about 2" up the vertical aft edge of the trunk, not down at the base where it meets the hull. At least, that's where the leak started. He glassed over the entire trunk to reinforce and strengthen to the whole structure. To hear him tell it, the trunk was less than 1/4" thick. As far as I know, he didn't cut away any of the deck liner.

That's interesting. I'm surprised that it's only 1/4" thick. I would have thought it was more than that. Thank you for the info David!

The winch is in the boat and operational...and there were no extra trips to West Marine, Lowes, Ace, etc. Should splash it this week for a leak test.

This subject has my full attention.
I looked at my winch in-place and cannot see any great corrosion.
New winch is great idea but post to Australia is over $300 ( $500 Total) so will take mine out (boat in the water)and look closely at it .
Not sure what I will see .

Regarding Keel-case damage avoidance I am working on a bladder idea but will make a separate post when further developed and water level in keelcase is known . but...So far... Ideas needed

Question...How ya gonna test it? Cut the cable?

With the weight, leverage, and forces being generated, seems to me a bladder would pop like a water balloon instead of slowly bringing the keel to a halt. Maybe just reinforcing the entire trunk head with carbon fiber/kevlar mat, especially the corners which appear to be the problem area, may lessen the possiblity of catastrophic damage.

Thinking back to my Navy days, maybe you can compartmentalize the trunk head so that if the inner trunk incurs damage, an outer water tight casing can keep the water out.

Looking at the trunk head, it appears you'd have an inch or two gap where the splits usually occur and room along the sides and forward to encase the trunk with an outer water tight casing.

I'm with Frank on this one...(except the wife already bought the Watkins).

Based on pictures, comments, etc from this thread, I am going to go ahead and lay a couple reenforcing layers of matting on the trunk.

Off topic, but, does anybody have the width of a wing keel (and a C-27 wing width)? We are re-working our sailboat trailer at the marina and I want to make sure a wing will still fit when we're done.

Thanks

This should cover it Tom; [url="http://www.catalina-capri-25s.com/forum/topic.asp?TOPIC_ID=18647&whichpage=2&SearchTerms=TRailer"]wing keel trailer dimensions

And as far as the bladder question, I'm sure they're rated for lbs of pressure but I think something like this is best left to boat designers and builders, not so much the after market add on.

Splashed the boat today (finally), so far so good, no water in the bilge (or anywhere else).

Great idea. Replace the wood panel trunk cover with a water tight fiberglass box.
The top could even open since it's above the water line so you could inspect the trunk. And it would be an inside the boat modification, no dropping keel, etc.

After a week in the water and one race, I found only a trace of water in the bilge (and that was after the boat was on the trailer). But, I have another issue, hoping that someone on the forum can help me with. After two days, I had hundreds of dead love-bugs in the cabin

Don't ya just hate those things? We have some love bugs up here Tom but nothing like Satellite Beach last week-end. Still, I put a fresh coat of wax on the car as I've tried about everything but found that they come off easier with a fresh wax job.

I do not have a swing keel C25, but I think the bladder idea is brilliant. Even if it is a sacrificial bladder (sounds vaguely religious, doesn't it?) if it protects the trunk from being damaged it's worth a lot. I would think an engineer could estimate the amount of force coming up on the heel of the swing keel.

Here's an idea: One could put a bladder in and fill it via a valve on the top of the keel trunk, and fit in a pressure-activated spray head. If the keel cable suddenly breaks then you could clean out the inside of the cabin as a side benefit. :^D

Re: love bugs, if they keep coming back, try one of those mothball cakes that come in a plastic container that has a coathanger hook on top, and hang it in the cabin. The smell might keep them away. Only takes a few minutes with the hatches open to air it out.

DavidP...love bugs are a twice a year event in FLA, they are a little worse than normal on the coast this year. They'll be gone by this time next week.

Love bugs aren't that smart. They just drift, not really going anywhere. most end up on windshields but they are horrible on the water when there is not much wind. TCurran.... got wet dry vac???

Also, they are not fond of cigar smoke. I've found that Arturo Fuente Dbl Chateau works fairly well.

Davey J, yup...they're so thick here this year you can suck'em up while they're still flying. BTW, the love bug comment was meant tongue in check...

I remember love bugs from when I was in college in St. Pete and trips home at holidays, and going to Disney World. I used to have a nylon screen that stretched across the front of our Cutlass Supreme and secured to the side panels at the wheel openings to try and keep them off the grill and headlights.
Nothing to do about the windshield except wash it frequently.

Tom C.-- I installed the new sleeve last week . The pivot pin hole in the cb was really worn irregular. I had to hand file 3 points in the keel to allow the new sleeve to fit. but other spots , had 1/16" more clearance . I glopped the hole with epoxy ( 2400# psi and 15 min work time) and then covered the ends of the sleeve with adhesive tape and shoved the sleeve through then peeled off the tape and it looked good . I guess time will tell. I was feeling a unexplained short drop in the keel when lowering and now feel that the problem was the pivot pin was sliding around in the worn pin hole. I will probably splash next week Memorial day weekend or so . Stay tuned..
