Hi Gia, this is pretty normal this time of year. It has to do with the outside temperature being colder than the inside when the dew point is below the surface temperature of the windshield. It happens on my truck and boat in the mornings. Cars and truck can clear fog on the windshield faster with the defrost as it uses the AC and outside air to dry the air. There are things you can do to reduce or clear the windows faster:
Use a dehumidifier
Use something like Dri-Z-Air which absorbs moisture from the air in the cabin (I use this)
Heat your cabin before you depart. If you are like me I like to board and go, so I don’t usually go this route. I will sometimes run the heater overnight if I know I might face windows fogging conditions.
Use 12v fans. I have one for each side of the windshield. Works pretty good, but takes some time for it to work. I also open and let fresh air in as well. I installed USB ports on the helm side and passenger side and picked up some USB fans. Given I also have an inverter I somethings run a more powerful 110v fan to clear the window faster as I depart.
I’ve heard using a defogger treatment helps as well.
Oh Yeah, keep that rag handy and keep clearing the window, it does help to clear it faster when using fans
I’m sure others have their methods so you shouldn’t be short on things to try.
These are Lots of good tips on dealing with moisture on the glass. I just thought of another... if you have a propane stove.... propane releases moisture when you burn it. So don’t use the stove. Eat your breakfast cold. 😋
Hi Everyone, The season for boating in my state (NJ) is almost done. I want to thank you all for your help this summer. --------------------------------------------------------------------------------------------------------------- In the beginning of next week, my NC895 will be pulled out of the water for winterization. All will be done by the mechanics from the marina where my boat will be held over the next 5-6 months. It’s going to be kept on stands and covered by a custom canvas (not shrink wrapped). I would like to ask you to please share with me your experience on what details and important points I have to pay attention to, in order to avoid any possible problems. Is there any sort of check list that you could give me? This process will be done by certified mechanics, but I’ve read and heard many horror stories and so am still concerned, seeing as how I don’t have the experience to double check their work. Just for info, some of the utilities that I have onboard: a generator, air condition-reverse heater, hot water exchanger and tank( never used this season), microwave and refrigerator. Any advice, personal experience, or ideas, will be greatly appreciated. Thank you very much in advance.
There are certainly many items to consider for proper winterization. There are two things that come to mind that are easily overlooked. Assure all fresh water and black water systems are either completely empty or have RV antifreeze. The cockpit spray nozzle is easy to miss. Assure the antifreeze is pumped all the way through until it comes out the spray head. The other concern is moisture buildup. Do everything you can to assure the boat is dry inside. For example, residual water from leaks in the hull cavities. And use a dehumidifier. Even though the boat may be dry and covered moisture will Collect over time. Don’t forget the tank will need emptying. I run a dehumidifier during the winter even though we use the LolaClaire year round. :.)
Hi Everyone, I have a question that I hope you will be able to help me with. I went out on the water around 6:00 am today; it was still dark out, with the temperature in the upper 50s and no humidity. Prior to leaving, I wiped down the windshield and the side windows both inside and out so as to clean off the condensate. Immediately though, they all fogged up again and we could not get them to stay clear . I tried wiping the windows down, using the windshield wiper fluid, keeping all of the doors and windows open, but nothing worked. I have had a serious difficulties to operate my boat to leave marina, using the starboard side door for the direct visibility... Of course after the sun came out, the visibility became better, but it took around 30- minutes before everything cleared up.
I think, the problem is the windshield glass quality itself but I was wondering, are there any tricks that you may have to keep the windows clear during the dawn hours? Otherwise, I found that it’s impossible to see in front of you, even if I put the spotlight on.
Your comments and advises are greatly appreciated.
I purchased a 12V fan, which plugs into the lighter socket on the dashboard and has a suction cup - you do have to find a flat-not-curved surface for the suction cup. The windshield definitely fogs up, but this takes care of the problem. The one I bought is this one but I'm sure there are lots of others that would be just fine. It's also helpful for spending time in the cabin on a warm day - the Jeanneaus are famously steamy inside with all that glass, but opening a couple of windows and pointing the fan at where you're sitting makes a huge difference.
