Now that's more like it!!
Whistle, knife, phone, tool kit, pump, spares (screws etc) - radio?????
I'll be a long way from the shore, tidal estuary with a long walk to the water so need to have everything I need with me.
You said "...on the water..". If you're including land, I would add a windmeter and you should ALWAYS have at least 1 knife. I also personally always keep my car keys with me. Unless you're blessed with very predictable winds, 2 kites - in order to cover a much bigger wind range. There's a lot of other stuff which could be added depending upon:
2. Type of lesson.
3. Student's ability/comfort level.
4. Distance from emergency services and/or medical attention.
I don't know what you mean by "tidal estuary" but I wouldn't be surprised if you'd need foot protection, sun block and a small inflatable raft/boat to shlep the stuff if the "tidal estuary" means shallow water. If it means mud or sand, a wide-tired cart (or a couple of slaves).
