I have a porta-bote.14' long and it carries a 8hp Yamaha motor. It does 22 mph with 2adults and 2dogs and fishing gear. It seats 5 and the best part is. It takes about 10 minutes to set up and wheel down to the water. It folds up to 5" thick and 2' wide and 14' long. They make brackets to go on side of trailer but we choose to install brackets under the coach and it only weights 96 lbs so it is very easy to slide in brackets. Look on Craig's list for some real good deals. Mine has been to about 30 states and still looks new. It is made out of plastic that is almost bullet proof. Just remember if you hit a rock, you will not have to worry about the patch kit.
