They also explain actions to take for crossing, meeting and overtaking situations.
Every pleasure boat operator who must give-way to another vessel, that means the operator who has to move, must take “early and substantial action to avoid a collision.”
The stand-on vessel must “maintain course and speed.”
Danger (Give-Way) Zone
The green sector on your boat, that sector defined by your green sidelight, is your Danger Zone or your Give-Way Zone.
This extends from the centreline on your bow (dead ahead) to 22.5º abaft the starboard beam, or 112.5º from the bow, along your starboard side.
When another skipper sees your green light, he has the right of way…green for go. When you have a boat in your green sector, you must take early and substantial action to avoid collision.
There are several exceptions to this rule.
The operator of a pleasure craft of less than 20m in length, or a pleasure sailing craft, shall not impede the passage of vessels which can navigate safely only within a narrow channel.
This generally refers to large ships or commercial vessels making way in a narrow channel where they have no room to manoeuvre. Ships may remind you of this rule by giving five short blasts of its horn.
