How do you like your waterskeeter? If you are happy with the quality, waterskeeter has a setup that might work good for you. It is 2 separate kb's that can be attached together to make one big one. It might be worth a look.

I was tempted to get that so my wife could go, but I wanted something with a high weight capacity that was still pretty light and could handle at least a class 3 river. I bought a Skykomish Sunrise from Dave Scadden for $999. With a capacity of 600 lbs and a weight of about 65lbs it can handle the 2 of us and our stuff for small lakes and stuff. I'm in the middle of designing a second seat and standing platform so my wife can go out with me. I'm hoping to implement it this weekend.
