So often, these potentially lifesaving titbits of information are well known as local knowledge, but don't get passed out publicly. Based on what I've seen, not everyone is aware of some of the more basic rules of boating.
Did you know the speed limit within 200m of the shore or a diving flag (or 50m of another boat) is five knots? If you are water skiing or towing a sea biscuit, it takes "three to ski" - a driver, the person being towed and a "spotter", someone on safety watch facing the skier.
Did you also know that when two power boats are approaching head on, each boat must move to the right (the opposite of the land rule)? You also give way to the person on your right (starboard), if a vessel is coming from that direction. And when you're in a channel, regardless of where it's coming from, if it's a ship then a smaller craft is always giving way.
