Tracking is OK, the rudder helps with that. Its quite stable, new kayakers have felt quite comfortable with me when it is set up as a tandem. A big bonus is that it can be configured as a single or tandem. One kayak can serve multiple purposes.
If I were more serious, had a long trip, or more dangerous waters I would want a single piece kayak. But this one is so easy to live with that it serves my casual kayaking very well.
