Murphy's Law
George, It's really a matter of taste, remembering that "Murphy's Law" is prevelant more so in water activities than normal life for the land lubber. A rule of thumb is if you fill it with air it will eventually leak somewhere. I've had an inflatable and it was extremely difficult getting in and out of the thing, maybe it's an age thing, however I stay in good shape. The hard dink that we now have appears to be the best thing we have purchased, in and out of it is solid and ya can't punch a hole in it with the normal daily routine that's accustome to boaters. The inflatable was nice storage wise, but with a good dink tow set up you really lose no speed while pulling it behind you. And as far as storage, ours only weighs 75lbs and its easy for two people to pull it up and store it on the foredeck of our H34. As far as motors the smallest is the cheapest and easiest to maintain, after all its purpose is to get you from point A back to the boat, it wasn't made for race'in. Good luck.
