I'd agree with the other reviews. Tough and quite light, but short and wide 38" at the gunwale (read tub). I bought it for my two oldest boys (9 and 12). I wanted it to be short so that they could maneuver it well and wide so that they can fish out of it with their little brother between them. They can also carry it without too much whining.
For my uses, I would give it a 10. A keel would be nice for tracking, but I find they they can be a wear point.
