So red on right as you return to sea.

Each type of mark has a unique combination of colour, shape, topmark and light. The driver must be able to identify these marks and pass them safely on the correct side. LATERAL MARKS Port and starboard marks are referred to as lateral marks. PORT HAND MARKERS Are painted RED and are associated with a CAN shape topmark or buoy. If lit, a port hand mark shows a flashing RED light. STARBOARD HAND MARKERS Are painted GREEN and are associated with a cone shaped buoy or topmark. If lit, a starboard hand mark shows a flashing GREEN light. When both a port and starboard mark are placed near to each other, the safe route is easy to pick - you travel between the two of them. This is the same whether you are going away from the sea (upstream) or towards the sea (downstream). SINGLE LATERAL MARKS In many situations LATERAL MARKS are not placed in pairs and so the boat driver will need to decide on the safe side to pass. The safe side to pass a LATERAL navigation marker is determined by your DIRECTION of travel to or from the SEA. Note: Heading UPSTREAM means in a direction AWAY from the SEA. Heading DOWNSTREAM means in a direction TOWARDS the SEA. Keep RED (Port Hand Marks) on your LEFT hand side (to Port) when going AWAY from the Sea (Upstream) [Marks match your lights heading into port] Keep RED (Port Hand Marks) on your RIGHT Hand Side (to Starboard) when going TOWARDS the sea (Downstream) [Red on right when returning to the sea - the system assumes you start at sea and approach an unknown port.] Keep GREEN (Starboard Hand Marks) on your RIGHT Hand Side (to Starboard) when going AWAY from the Sea (Upstream) [Marks match your lights heading into port] Keep GREEN (Starboard Hand Marks) on your LEFT Hand Side (to Port) when going TOWARDS the Sea (Downstream) [Simple!] Graham.
