Installing a Kasco floating display aerator in 1/2 acre neighborhood pond. There are no docks or boats. I'd like to get a simple, inexpensive inflatable boat to install and service the floating fountain as necessary, and otherwise collapse and store when it's not needed.

It's just gotta be sturdy enough to hold me, the fountain, and the two weights that anchor the fountain (maybe 300 pounds total) and not so flimsy that it tips over when I reach over the side to drop the weights, or take the fountain in and out of the water.

Any suggestions? I see some Intex inflatables on Amazon that cost around $50 and are rated to hold 2-3 people, 300+ pounds, and are 4' x 7' or larger.
