Three amendments to the Sailing Instructions apply from 3 July 2026.

Amendment 1

This changes Sailing Instructions A General, therefore it applies to all competitors. Instruction A11 already requires competitors to keep clear of commercial shipping. This change extends that to all large power-driven vessels, including naval, customs and Irish Lights vessels, cruise ships and their tenders.

Notes for Competitors

Dun Laoghaire Harbour Berth 3 is now reserved for naval vessels. There may be significant naval activity in Dun Laoghaire and in Dublin Bay during the remainder of the season, due to the Irish Presidency of the Council of the EU.

There is a recognised anchorage for Dun Laoghaire Harbour in Scotsman’s Bay.

For various reasons, a vessel may hold station inside or outside the harbour. It should then be regarded as being “restricted in its ability to manoeuvre” under the International Regulations for Preventing Collisions at Sea. That means that it has right of way over a sailing vessel.

Do not assume that a stationary vessel is anchored, unless you can see an anchor chain in the water. If a vessel is not anchored or moored, it is “under way”.

Do not sail across the bow or close to the bow of any large vessel under way. Even if the vessel appears to be stationary, it may be about to pick up speed and alter course.

Amendment 2

This applies to all courses using a committee boat. It allows alternative start and finish lines to be used if the committee boat is unable to anchor as normal. To do this, it changes Sailing Instructions Supplements B, C, D and G.

Amendment 3

This applies to dinghies only. It allows the start sequence to be shortened for the second or subsequent race of the day, by combining starts or omitting starts. The fact that the start sequence is being changed will be signalled by a long sound signal as the orange start line flag is being raised. This requires changes to Sailing Instructions Supplement D.
