The Menai Strait – Application of Rule 9 'Narrow Channels'.

Mariners are reminded of the requirement to comply with Rule 9 of the International Regulations for Preventing Collisions at Sea 1972, as amended (COLREGs). This particular rule refers to 'Narrow Channels'.

Particular attention is drawn to Rule 9(b), which states that a vessel of less than 20 m in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway.

For most merchant ships the buoyed channel throughout the Menai Strait, from Caernarfon Bar to Puffin Island, is considered to be a narrow channel.

Please see the attached extract from the COLREGs, which lists Rule 9 in full. Users of the waterway should ensure that they are acquainted with the requirements of this rule and all other relevant rules contained within the COLREGs. Also attached is some guidance to small craft on what to do when they meet a ship in the Strait.
