Go with a PortaBoat. It fits our sized boats just fine. It will plane one person with a 3.5 HP outboard. Lasts a LONG time, even stored out in the sun in the Sea of Cortez. Will NOT deflate and you can drag it over rocks with NO damage!
And on top of all of that, it's so ugly no one will steal it....
I just ordered a new one. Our old one that I am replacing was bought in about 1995.

By the way, if you are unsure, and can wait, and you make it to Pacific Sail Expo, you can try mine.
I'll loan you the keys to our car....
