Looks like fun...in the right environment. For example, our local lakes have vegetation that comes all the way up to the surface. Hit a "kelp" bank at speed and it will not end well. I've had the experience of getting stuck in one such beds in a rowing shell. Let's just say it wasn't fun at all. Open water with a low probability of colliding with anything near the surface? Yeah, this looks like a blast!
