Conwy Notice to Mariners 16/2022
All mariners are advised that a new yellow conical special mark, with a 10 knot speed advisory, has been laid to seaward of the Beacons Pontoon in Conwy Harbour. The mark position is Lat. 053° 17.753’ North, Long 003° 50.422’ West. The mark is lit with a yellow lantern, flash characteristic Fl Y 10s.
The 10 knot speed limit is a maximum and certain vessel hull types can still generate an excessive wash at speeds of 10 knots or less. It is a matter of both good seamanship and safety to ensure excessive wakes are avoided so as not to potentially endanger other harbour users.
