Fuzzy

Hi all, I'm new to the forum and have a quick question. This weekend I am taking my eleven year old Son to Poole, we have a boat fishing trip planned for the Sunday but I want to take him shore fishing on the Saturday. I am a total sea fishing novice (but have been course fishing for years) I have two cheap beach caster rods/reels. Can anyone reccomend where would be a good place to fish from that is reasonably close to Poole (or even better in Poole!) Any suggestions on bait and rigs would also be appreciated as it will all be new to me!! Many thanks in adva
