Mildew suppression/prevention

So we sail on eastern lake Ontario where it has been a very wet/humid summer. We were on our boat last weekend after a couple of weeks away and found a faint line of mildew where a stowed sail was touching the hull. We unloaded the boat of all sails/pfd's etc. and did a thorough inspection. Found what I would call some minor mildew. We plan to do a thorough scrubbing of the boat this weekend with a mild bleach solution. Just wondering if anyone has any specific advice for products that stink less than bleach that work for suppressing mildew.

Put in a solar vent or two and getting the air moving, will go a long way in stopping the mold and mildew.

Ventilation and sealing off the leaks are the best way to prevent mildew and mold. If you don't stop the leaks, it will take a lot more ventilation to prevent the mold.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Yes!!! Or you could try desert sailing I hear that's very dry..

In all seriousness bleach & water works well but DO NOT let it sit in the bilge. Bleach & stainless keel bolts don't like each other. Be sure to rinse and dilute any bleach water that makes it to the bilge. Oh and wear rubber gloves.

Solar vents REALLY work!!

I agree wth the comments above about the need to increase the amount of ventilation.


Here in the south, I use plain white vinegar to wipe up any mildew that occurs. It works pretty well, wont dissolve your boat and doesn't drve you out of the boat.

There are "oxy" cleaners, and hydrogen peroxide, and fancier ways to get rid of mildew but bleach is the most cost effective. Remember that you want to THOROUGHLY RINSE any chemicals off the sail and the hull, and if you thoroughly rinse off bleach--there won't be any more smell. Think of the odor as a good thing, it tells you when you have rinsed well enough.

With the heat and humidity the east coast has been having this summer "a trace" of mildew shouldn't be a surprise.

As others have said, the solar vents are one of the best ways to combat mildew. Maybe more expensive than mildecides in the short run--but it's so nice NOT TO HAVE TO CLEAN!

Which Day/Night Solar Vent?

Which Day/Night Solar Vent?
I just got a new-to-us 28' Pearson, and I'm interested in getting two Day/Night Solar Vents (as described at BoatUs's boattech/vents page. But which one should I get? In my opinion, mildew and mold are lethal for boats, so this is at the top of my list and I want to get a good quality, reliable one.

What is your experience with Day/Night Solar Vents? Which ones would you recommend to get, and to stay away from? Good warrantee? Am I looking for the right thing, or has the technology been updated since the writing of that BoatUS article? Thanks!

PS: We have two windscoops in on the cabin top in the middle of the boat.

To add to the suggestions above I burn a hundred watt light bulb 24/7 while dockside and along with the solar vent have had no mold issues.

Leaks are also a problem. Unfortunately, I am often away from my boat for a couple of weeks at a time. When I return to it, there is usually a bit of water in the bilge and a bit more in the lazarette. This really annoys me. Last weekend I sat on the boat for a while during pouring rain. I couldn't see water coming in anywhere. I think that it may be an issue of wind direction when it is raining. I am still mulling over what I am going to do about this. My boat is an older Shark24, and when the companionway is closed, there are some small openings. Any input is appreciated.
