Bucket boat to get you on the river is great. Looks like a fun ride and you'll get lots of great experience learning how patch rubber with it too!
However, those aluminum angle brackets sticking up along the sides scare the bejesus out of me with the thought of what could happen to someone stepping/falling/getting thrown into one of them. That could be a lot of stitches and patchwork of the non-so-fun kind.
Ditto on what NorthernAZ, except before the first trip.
Nothing in the world is more yielding and gentle than water. Yet it has no equal for conquering the resistant and tough. The flexible can overcome the unbending; the soft can overcome the hard. - Lao Tse
