Patio Mist type system for Pontoon
 

I was out in my Aunt's pontoon boat last weekend and it was hot as ****. For most of us we just jump in to cool off or whatever but my Aunt is in a wheelchair so her cool-off methods are limited.

I got to thinking it would probably be fairly easy to DIY a water mist system in their bimini to help keep the back half of the boat shaded and cool, but the front is still open to the sun.

My thoughts:

* Hose + filter to lake to pull water (or use a hidden 5-gallon pale or something as a reservoir) for supply water

* Wire a RV Water pump to move the water and hold a fair amount of pressure in the line(s) to get a good mist rather than a dribble - Example of Pump

* Pump supplies water to a "patio mist" kit from amazon. I figured 4-8 mist heads under the bimini section of the boat. Perhaps pipe more to the bow with some isolation valves. Example of a mist kit - https://www.amazon.com/MistyMate-160.../dp/B001ET335A



.... anyone have input on if this would work? any reason 45 psi wouldn't be enough pressure to get a mist vs. a dribble.

45psi should be fine. 60psi would be better.

the higher the psi the finer the mist. the finer the mist the quicker it evaporates providing the most cooling effect and leaving the least amount of water on the deck.

Keep in mind that the higher the output and the higher the pressure, the higher the amp draw will be. High amp draw equals short battery life. Depending on how long she floats, it may be worth having a second battery installed and isolated. Most toons have outboard motors and I don't believe they have a high amp alternator like our tow boats have.

Home depot has a really nice cordless misting fan that fits on a five gallon bucket . It uses a Ryobi type battery which it comes with but you can get a much better Ryobi battery for even longer run time . I have the older version which is more a conventional mister with a hose and nozzles that sits on a bucket and uses a Ryobi battery . We use it camping at it works well . Ive always used lake water its doesn't seem to mind a bit . Attachment 43116

BTW the conventional one is only available on Ebay I think .

Having had some of those misters, I tried exactly what you are proposing on the boat.

It is possible, but those misters are looking for close to 70psi which is what residential service pressure is otherwise the misters will not work and just drip. Very few 12v pumps can put out that pressure without being huge or costing quite a few bucks. I ultimately abandoned the idea.

Thats why I went with the one I posted above . They work as good as my patio mister that runs off the house other then dealing with batteries its perfect .
