After 3 summers of paddling our Tarpon 160i's all over the Eastern Shore of MD we give them a 10+. Initially we paddled sheltered areas close to shore but as we have learned the capabilities of these kayaks we have ventured into large open river and bay areas. They handle light to moderate chop without any loss of control. In windy conditions we have no complaints on their ability to track in a straight line. Waves from the side often result in some extra water in the cockpit, but the stability of these kayaks is amazing.
We have found that using a paddle a length longer than normal results in less paddle drip in the boat. In rough/windy conditions wearing rain pants serves the same purpose as a spray skirt. We carry both on a set of Thule Slide and Glide racks on top of a Toyota Highlander without any trouble. Due to the weight they would be extremely difficult for one person to load, although we have a friend who loads his alone all the time. We would never consider replacing these kayaks with a Sit inside.
