Im buying a kayak, to be used south coast uk. i have looked at dagger and perception? - perception kayaks caspia

and because they look good, i wouldnt mind them.
Is it possible calmish national sea kayaking on a sunny day? such as air bags and their use? Also, how easy it is to keep for yourself, if you move?
