Look up hungry bear or check out the jupiter boats too.... jupiter is 30 minutes south and has some AWESOME boats to go out on. Email me if you have any questions, I lived up there for awhile before moving to miami.
My Dad snow-birds right across the river in Jensen Beach. Off-shore can be good can be bad . . depending. (Though usually pretty good). Don't neglect the river & surf though. One thing I love about down there is you can put a serious bend in the rod standing in waist deep water or off a bridge . . or a shallow water charter.
