all the knockers above need to pull your heads in...
people who can't navigate don't belong on the water at all. Navigation is part of your general safety obligation.
If you can't work out if you are in a green zone or not, you sure as sh!t are not capable of being safe out on the water.

With reference to the comment above, very lame mate! I am asking because I dont want to spend half MY TIME CHECKING IF I AM OR I AM NOT IN A GREEN ZONE.
Really a COMMON SENSE QUESTION FOR ANYONE HERE.
