Mick,
Good for you. I fish from both Kayaks and Canoes. Each has a different feel and different advantages. As you move into the world of kayaking note that a smaller kayak turns more easily than a longer model. With a 9' you tend to zig zag as you paddle from side to side so it uses more energy. If you are paddling less than a few miles during each fishing excursion you should be fine. If you are doing longer paddles against current or across windy lakes it will be less efficient and you will tire faster. Because of the zig-zag you don't point upriver as much and your bow is more likely to catch water and be harder to handle. Conversely it is easier to manoever in small spaces, load and unload from the car and is generally stealthier.

All that being said enjoy it and keep these issues in mind because you'll soon be looking at other boats. Its a rule, once you get into it you always want another one. Bigger, faster, smaller, lighter better seating etc.
