If you get a 10-11ft all round board they are great for most conditions and flat water and small surf. If you go for longer paddles conditions can change and those boards do not cope very well if the wind and chop increase. A touring board is good in flat, choppy, small waves and stronger winds and will make it a lot easier to get back to your car if you have go battle a head wind.
12-14ft x 26-29in will be great for you if you don't want to try surfing, if you do buy a second board and have choice and more fun.
i started with the 10fter pictured then moved to the yellow 14fter which was a great board and have moved to a Carbon 14fter which is narrower which seems to be a natural progression for most people.
