I've got a small 3ac pond I'd like to have something like a mini/small pontoon boat to putter around on. Any experience/recommendations for something like this? Want something to stand up on, rake nuisance vegetation, carry a couple of kids, etc. Not a Jon boat/canoe. I've seen the Pond King/Hotwoods sites but there have to be other options. Or even a source for small pontoons to DIY.
 
Inflatable might be an option but would prefer rigid. Full-size pontoons seem easy to find but smaller/shorter not so much. Trolling motor for sure and forgot lawn chair beer drinking.
 
Just doing some research.
10- 10ft pieces of 4" foam core pvc will run you less than 200 bucks.
9 pieces will make 3 10' pontoons, in pyramid stack. You'll want some 45s and caps.
Lemme work the numbers later. Its late but I can figure your displacement and what you'll need.
 
Yeah....now I'm studying on it, I won't sleep.
4inch 10ft
135lbs per 100ft
.3333333333x10
3.33cu ft per pipe
9 pipes
3.33x9 29.97cuft
So 30cuft
30x7.48 gallons per cuft
224.4 gallons
X8.34
1871lbs of water
Now, thats the amount to "sink" the pipe. Still a hell of a lot of displacement.
Weight of pipe, deck, etc....
Hold 6 or 700 lbs easy.
Now I'm thinking about building one.

not sure it helps, in the seaplane world, the aircrafts floats must be able to support 180% of its weight. Good rule of thumb

I had a big long reply and lost it somehow.

No, it doesn't help. What does the plane weigh?
Support?
With how much displacement?
There are a lot more numbers attached to your statement....a lot.

The biggest factor being boats aren't sea planes and seaplane aren't boats.

I used to work with a guy who wanted to build a raft for his quad so that he could ford a river during his upcoming hunting trip. He asked me to assist. He'd made a wooden 'box' just big enough for the quad to sit on, and get strapped down.

It was 8" thick. I tried to explain to him about "floatation" and how that works. His opinion was "this is good enough, I know what I'm doing, and are you going to help me or what?"

I then tried to explain to him the theory (Law) of displacement. His reply to that was, "I'm going to fill the box with extruded polystyrene insulation, so it'll be 'more floaty'."

It was about that point where I gave up, bit my tongue, and simply lended a hand to a co-worker.

He took his "USS Minnow" to a nearby river that weekend, to try it out. After the quad became an instant keel, he and a few others were able to locate and retrieve it all, by seeing this 'un-natural corner' poking out of the water, sporadically. Mostly whenever the handlebars and/or other luggage rack equipment was hitting a rock down below.

Oh, was he mad.
 
Another option is you could build a floating dock and a fixed dock, hook the floating one up to the fixed one and if you want to tool around simply unhook it and motor it around. Could probably be made for cheaper than one of those small boats and it can be left out year round.
