Its all dependant on your weight and if you only plan to surf or if you want to do some distance paddling also. Shorter boards are harder to ride but turn better on waves. Long boards paddle distance better, are easier to start on. Better to go bigger to start with, get your style sussed and do heaps of flat water paddling. Then in only a couple of months you could sell it and go for a surfing board. Keep in mind you actually feel warmer on a SUP than surfing so its good all through winter also. If you are only interested in surfing and are a light weight or rekon you have super balance and prepared for a challange, buy a shorter board straight up.

P.S Chocko - can be enjoyed on lakes and rivers also. You probally could where board shorts alll year round as you wont get wet....
looks like something is sneaking in wed next week. some good oldfashioned optimism should put a stop to that...
I've got a demo Starboard 9'8" that's only been used once.
It's got a mast track so you can sail, surf or paddle on it. Take it out for a try and if you like it I can do you a ripper deal!
