I bought a purple one of these used a few weeks ago and have had it on a few flat-water lakes and creeks (2 trips a weekend, 5 weekends). The boat is nice. If left stock, it is a plain-jane kayak with a large singular cockpit, earning it the "Kayoo" moniker. Because of the kayak characteristics, it can go where canoe's do not dare. Because of the canoe characteristics, it can hold tons of gear (14+ feet) and is good for those claustrophobic types not liking hip hugging kayak fitting.
The seats are neat due to the ability to reconfigure them, but they are hard plastic, without cushioning... so take heed. I have padded the seats with after market self-adhesive pads (much better), added paddle clips (convenient), deck rigging (bow) and two cat-bag dry hatches (5.5 inch) in the stern. She is now a custom, comfy and convenient kayak for two suitable for 6-8 hour trips anywhere.
I wouldn't trade her for the world.
We have had our Walden Spirit tandem for just over a year now. My wife and I enjoy nature photography, fishing and just general paddling. It is a very stable yak for all of the above.
I was a little worried about how the boat would handle when I was alone. I had nothing to worry about. The seat adjustment is very efficient and the yak tracks well and steers better than I expected. We are going to Texas in a month and plan to take it with us to fish the shallow salt marshes along the Texas coast.
We would rate it first class.
