Minnie- how are you moored?
Good question. We are at a slip, with the aft furling slot of the mast facing the prevailings. However, I'm not sure the big rains really come with prevailings. I will have to think this one over.
Also changed out my lower bilge pump to one that runs for 15sec after float switch turns off. Decreases back flow without a check valve. Much dryer bilge.
We have a small lower sump in the bilge with a diaphragm convenience pump. There is always about a pint of water in the 8"x8" section of bilge, but it turns over frequently, since all condensation is hosed directly to this sump and I do scrub it out occasionally. I do not believe this is a source of odor.
Our AC unit drains into the bilge. Believe this is fresh water as it's condensate. Agree AC units can cause all types of diseases such as legionaries but doubt it as source of bilge smell beyond keeping bilge wet.
I agree, and this isn't the stagnant source of water for us either.
Lastly strongly agree with Rich. We smell. We shed hair, skin, oil, and dirt. We rapidly habituate to smells. We are the worse judge if our boats smell after we've been on them for a very few minutes. A wipe down of all surfaces with weak vinegar/water solution and one ( yes just one) drop of dawn keeps the boat smell free.
Totally understand and agree with this point. We clean surfaces pretty well, I believe.
I'm convinced the odor is from two specific sources. I believe I mentioned the odor is slight and occasional.
First is mast water that finds its way to corners, where it either lies beneath the lip of a limber hole or collects at the intersection of a rib/stringer. These places can be below tankage or other obstructions, where it's very difficult to vacuum out or keep clean of dust, etc.
The second is the cup or more of sea water that enters each time I remove or replace the speed wheel. It's an awkward spot, which is difficult to dam up, so I can keep the ingress water in one spot. One of these days, I will have to disassemble all the furniture/cabinetry in the area to dam it. It disappears under the sole and not until we go out sailing/heeling, does much of it finds its way to a place that I can clean it out.
When either of these two sources of water collect and stand for any length of time, I can shine a light on them and see the mold on the surface. Odor. These tablets seem to be preventing the mold from forming.
Best purchase we made was a very small but powerful hand held plug in vacuum. The battery ones just don't cut it. Vacuum everything then wipe safe surfaces, a bit of chlorox followed by immediate water flush down the drains= no smell.
I think we have the best of both worlds. I bought a Dewalt wet/dry vac that can both be plugged into 110v, as well as run on 18v batt. We almost always plug it in. I use it to vac water I can reach.
[quite]Do bilge cleaner once a year. Stuff's nasty....[/QUOTE]
Me too, sometimes twice. I've liked TufEnuf bilge cleaner. It's also an enzyme and it seems to foam less, when I vac/pump it back out. Some bilge cleaners foam like a washing machine, which is nasty.
