Could it be this?
http://www.visitmyharbour.com/harbours/solent/portsmouth-marinas/expanded.asp Royal Clarence Marina.: The Marina benefits from very deep water and good shelter, and can handle very large yachts of up to 65 m. The entrance is marked by a series of green posts which need to be left on your starboard side as they mark drying banks.
