I was amused that they elected to pay the weight penalty of a stove, until I saw they're carrying around an outboard motor. Love the idea, wish I were rich enough to really consider one of these for myself.
Also - thrusters in the floats? I haven't seen that before. I never did get a seaplane endorsement, which you'd need for one of these. That's a neat idea, even if it isn't theirs. I wonder how much they're needed, and if the added control on the water is worth the weight. I have to imagine they'd be great if they offer enough degrees of freedom (and are easy enough to understand how to use).
