Here's something interesting I stumbled accross.... The best way to describe it is as the lovechild of a modular sit-inside and a jetski. It still looks rather like a kayak in places, and it disassembles for transport, so I guess it's topical

The main hull section is 85 pounds and the motor section is 100. I suspect that would make assembly on uneven ground a bit of an adventure. I suppose the answer to that is to get 2 of them so you'll have a friend to help with assembly
