We have had our Caretta for two years and have paddled it extensively on the Gulf of Mexico and on the Great Lakes, including a 150 mile trip that included three days of paddling into the face of small craft warnings (big wind and waves). The boat is rock solid and fast, it handles well in confused seas and is comfortable. It is fast because of its long length (21 1/2') and carries lots of gear. The only downside is one common to all tandems, the ride is wet in front. Another thing we really like is that its long length makes it possible to paddle on opposite sides in rough water, enhancing the stability of the boat. I've never seen a tandem that compares to it.
