learningagain, I've never been to Sanibel. Heard there's awesome
shell collecting there, though. Regardless, I wouldn't go out on
a private charter, with a youngster. Pricey, possible seasickness, etc.
Now that your son is "hooked" on fishing, don't spoil it with a rough
trip. The whole idea is to let him have fun and catch fish.
Action, not waiting hours for the "big one", in rough seas.

Good luck!
