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 this summer, not everyone is aware of some of the more basic rules of boating. The Northland Regional Council's website is well worth a look - and not just for novices. Even those boaties that consider themselves experienced should take a look.
Did you know the speed limit within 200m of the shore or a diving flag (or 50m of another boat) is five knots - or walking speed. There is an excellent reminder that 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 powers boats are approaching head on, each boat must move to the right (the opposite of the land rule obviously).
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. For more information on safe boating, go to www.nrc.govt.nz/safeboating
