You need a boat, it can be more complicated than it looks. You can stand in lots of areas but not all. There can be adverse currents, offshore or onshore for that matter particularly near the cuts. If your kite is down and you can't stand up, out you might go. Some nice tiger sharks have been seen over the years off that flats in that area too. Best advice go out there a few times with a good sea taxi operation, ask a lot of questions, observe things closely, then decide whether to try the canoe approach.
The release was in North Miami, seems to be repaired.
