ive been fishing for 2 years now and have never caught a blimin fish! please tell me where i can be sure to catch something!!!!

I am going to Gulf Shores, AL, for a week beginning this Saturday and plan on fishing off a inflatable rubber raft 50 – 100 yards off the shore. What baits/lures should I use? What kind of fish can I catch? What time of day is best/worst for fishing? Any tips would be helpful.
