My daughter has been bugging me for a kayak for years, to use on sailing trips, to take on vacations, and to prowl the local canals and streams. We've rented and borrowed sea kayaks. We took a whitewater class together, when given one as a Christmas gift by my wife. No, we have no interest in white water, but the class was great fun and we learned a good deal.
Perception Impulse and I'm happy with the choice. We chose a sit-in kayak because they are generally faster and lighter, are drier in cold weather, and carry "stuff" better. Sit-on kayaks have the major advantage of not swamping if you flip one in the waves and being easier to re-board from the water and are probably better for summer sailboat accessory use. Make a choice.
Great fun. Great for exploring the marshes and shallows. Great for a sun-set exercise spin. Great for providing Mom and Dad and daughter dividable transport.
