Boater Safety / Courtesy Course - Give your input

If you were to put together items to cover in a boater safety/courtesy course, what items would you feel are important to include?

I thought of these items off the top of my head but I'm sure I'm missed a few:

Backing down launch ramp
Launching the boat
Re-loading your boat onto the trailer
General functions on the boat (covering all switches and boat functions)
General maintenance of the boat and trailer (including each use, and general upkeep)
Proper weighting and speeds of the boat for wakeboarding, surfing, etc.

Convenient options to put on a boat (such as perfect pass, a heater, bimini, newt juice sprayer, gator grip, etc.)

I also thought of general courtesy / safety items such as:

Not pulling up in front of other riders
Not doing power turns (and why)
Keeping a respectable distance from other boats, docks, riders, etc
Towing a wakeboarder, surfer, other water sports
Driving double-ups
State / Coastguard rules and regulations


What else do you feel is important?
