Re: Mystery water in bilge in CAL-29

I noticed a similar problem to Barry's on my O'day 35 (also similar to Barry's ).

The wet exhaust hose that ran from the mixing elbow to the waterlift muffler (one of the few hoses original to the boat) had a longitudinal crack in it where it met the muffler. It looked fine, until I removed it. I would get about gallon every hour of motoring. This hose has since been replaced, and I have added a CO detector to the main cabin.

Re: Mystery water in bilge in CAL-29

I think the water tank is your problem, Mine a Cal 28 is a fiberglass tank with a screwed down top , The seal is caulked . It is under the Vberth , where is yours? ..Dale

Re: Mystery water in bilge in CAL-29

The suggestions on this thread would take a few hours to confirm or deny, if not longer. Determining if it is salt or fresh water can save a lot of time.

Yep, good idea, but absolutely determine if it's ANYWHERE in the plumbing for the head, holding tank, macerator etc, BEFORE tasting it. Don't ask

Re: Mystery water in bilge in CAL-29

These are all good suggestions. The water tank does seem very likely - it has a vent in the top of it, of course, so having spillage when heeled or rolling is just about unavoidalbe - but you may well be hesitant to taste the bilge water. So, instead, drain most of the water from your tank, maybe filling a couple of gallon jugs to take with you next sail. If you still have water in the bilge afterwards, keep looking at the other suspects.

Re: Mystery water in bilge in CAL-29

Can't recall.. is the Cal 29 a bolt-on or encapsulated keel?

Re: Mystery water in bilge in CAL-29

Thanks everyone for the thoughts! Good ideas for me to check. The fresh-water usage is definitely something that I do only on big sails so checking the tank for the cause and inspecting the lines from it to the pump to the sink will be some of the first things I check.

Draining it out and seeing if it returns after the next sail might be a good thing.

Keep the ideas coming!

To answer your question, it's an encapsulated keel. No keel bolts for me!

Re: Mystery water in bilge in CAL-29

The water under the engine might not be reaching the top of the baffles, at rest. However, what happens when you go sailing and you are healing? The water then slops over the baffles. Result - water in bilge.

My Bristol does this all the time.

Re: Mystery water in bilge in CAL-29

Your engine raw water system may have a non return valve vented loop type thing, Vetus make some and they are great however they require peorodic cleaning or they start to ooze water out the drain pipe into the engine bay.

One way to check that, and freshwater cooling system is to put empty plastic bottles under any drain pipes under or around the engine.

Tasting the water will not get you anywhere unless theres a LOT of water. A couple of gallons of fresh water sloshing around the bilge for aweekend will taste like salt, or worse.

Dont go ripping out deck fittings etc until you have done the normal stuff of lose hose clamps, vented loops, etc.

Re: Mystery water in bilge in CAL-29

You could put food dye in the fresh water tanks. Then check the color of the water in the bilge after you sail.
