OldTown Rush (is it the Otter theses days?)or Perception Prodigy 10 would be my suggestions from my personal experience.
Both are very stable, both have large cockpits. The Rush is a bit more comfortable and is shorter\maneuverable also it is lighter than the Perception.
It would be worthwhile to look at an inflatable kayak, super light and easy to transport, though I've never used one my self.
