If you're looking for that all purpose boat, Look no farther.
The Rogue 10 is what i feel is my first REAL kayak. I also own a Future Beach Fusion 124, fishing kayak, sold a future beach fusion 10 (cockpit was so big it might as well have been a sit-on-top) And a Perception Sport Rhythm 11 {read my review}
The Rogue has it all. Drop the skeg and track your line. put it up and spin it on a dime. Learned how to roll with this boat in just 3 classes. Best of all, this boat was designed with REAL whitewater capability! I haven't had the time to put any real miles on this one yet, but I can spend 6+ hours rowing and rolling the Rogue on the lake and never feel exhausted.
If you only want 1 boat, buy a Rogue.
Enough said.
