Yeah, get the EPA to breach the underground dam and see what happens.

Until its repaired I would not store the boat ashore in a freezing area.

I owned a lobster boat that had a water ballasted keel. I know nothing about this boat but just asking, does it have a water ballasted keel?

Was your keel open to the water around it?

Yes, used the water it was in. Not too different than sailboats that have water ballasted keels.

Thanks again guys for your input. I'm a full time live aboard working 60 hrs per week so we can make this happen now instead of "some day". We dialed back our budget to do this and I'm trying to do all repairs/upgrades myself. I'm very confident in my abilities but this boat thing challenges my basis of knowledge at times. Thus, you guys. I appreciate your wisdom and input. I know these things aren't rocket science and I want to make sure I do things "right" the first time and be proud to know that when the day comes that I sell Mollie, the new owners will think well of me and my efforts. She is a great boat and fit perfectly into our "let's do this now" budget. I'm pretty anal about stuff and have a list a mile long of things to do, both must do and need to do. You guys will surely being getting more questions.
My next thread will be of a water damage/delam issue that I've been working on around a port light in the forward head. I'm pretty happy with how it's turning out. Pics and info to follow.
I appreciate everyone's input and quickness in responding. I hope that other newbies like me will also be able to gleen new info for their expanding basis of knowledge in everything boat.

If the water in the keel is open to the sea water around it, it would add no additional weight to the boat till the boat was some how lifted up out of the water.

Water ballast is usually in tanks well above the WL and as far outboard as possible.

I am not an expert on water ballasted keels. Did a little search and found numerous sites on it, especially for sailboat keels.

Your leak

I agree with Capt Bill. You can't really do much till your next haul out. So a temporary fix with an epoxy or caulking compound that will seal a wet leak could keep you boating till you haul your boat.

Once you haul your boat, get a grinder and start grinding where the leak is coming from. You have to expose the rot, and there will probably be rot if its been leaking away. You might be able to get to the leak from the outside to see if there is any serious de-lamination. Once you have uncovered the full extent of the damage, which may or may not include your shaft log, you can have a better idea of what your options are.

A water ballasted keel seems to be unusual for a Defever 42. I have a Marine Trader 41, which is almost identical to a Defever 42. The keel on these Tawanise boats is 'indeterminate'. In other words, it could be wood, fiberglass, concrete, or a smattering of all three. But once the outer layer of the keel is breached from either a grounding, blistering, delamination, or all three the water will enter.
