I bought the 14 foot Xplorer because I live in Western Oregon and I use the Willamette River as my Gymnasium.
The river has a current but, in the mid Willamette Valley, it's not enough to stop the Xplorer.... I paddle upstream on my knees and then the fun starts... downstream, standing, Blue Herons, Beavers, all my best friends witness the agility and speed of this really fine inflatable board. I couldn't be happier and I can't tell you how well it does on mountain lakes,,,, you don't even get your feet wet,,, although sometimes,,, I want to. This is a great purchase and I love this board...
