Re: porta-boats?
I did not own one, but a good friend did. It was a very neat idea, but no so practical.
I don't remember the size he got, maybe a 14', but that sucker was heavy. It took at least two people to move it. In order to operate the boat a couple of pieces needed to be screwed together which took sometime and with the flexible plastic, lining everything up was somewhat challenging.
I do have to say that the boat did work though. We only got to go out in it once, but it did work well. We went out with close to 700lbs (3 hefty souls) of people in it. Moving around in the boat was like walking on jello. He powered it with a 5 hp honda. It was great for getting into the shallow mud flats and going out where a regular boat just couldn't make it.
The worst thing was the nick names that every one gave it. I called it the porta-potty, it is made of the same type of plastic. The list went on and on, porta-joke, porta- fill in the blank.
Unfortunately Katrina washed the porta-boat to a better place. Like I said before I only went out in the boat once, but once assembled and in the water the boat was good.
