Sailing Instructions Amendment 4

Saturdays 29 August & 12 September

On the dates above, the Red Fleet and Dublin Bay 21s are scheduled to race from Corinthian. Due to the ILCA World Championships, the races will be in Scotsman’s Bay. This amendment to Sailing Instructions Supplement B allows Course Card 4, Thursday Red Fleet, to be used. To provide longer races, it allows a course to be repeated, or two courses to be combined. The Race Officer will also have the option of using a Platonic course, as in the original Sailing Instructions. Competitors should keep a listening watch on VHF Ch.74 before and during racing. The finishing line will be approximately upwind of the last mark but may be farther upwind than normal. To avoid confusion, with long courses confined to a relatively small race area, this amendment also prohibits boats from crossing the finishing line unless finishing. This amendment affects Sailing Instructions Supplement B. The changes are shown in full below. Brian Mathews Vice Commodore 19 August 2026

SI Supplement B – Fixed-Mark Courses, Committee Vessel In section B5 The Course, instructions 5.12 and 5.13 are added, as below.

## B5 The Course

5.12 On Saturdays 29 August and 12 September only, if a course card is used, it will be Course Card 4 – Thursday Red Fleet. If the committee vessel displays a letter followed by a number (e.g. A3), the course will be the corresponding course on the course card, sailed once, as normal. If there is a number preceding the letter, the course shall be repeated that number of times. For example, the display of 2A3 signals that course A3 shall be sailed twice - round all the marks of A3 in the order specified, then sail to the first mark of A3 and round all the marks of A3 again, in the order specified. All marks shall be rounded to port, as on the course card. The display of two letters and two numbers signals that the course is a combination of two of the courses on the course card. For example, A3B8 signals that boats shall round all the marks of course A3 in the order specified, then sail to the first mark of B8 and round all the marks of course B8 in the order specified. All marks shall be rounded to port, as on the course card.

5.13 On Saturdays 29 August and 12 September only, when the finishing line is active, signalled by a blue flag flying on the committee vessel, a boat shall not cross the finishing line in either direction, except to finish. A boat that is identified as breaking this rule will be scored NSC (did not sail the course) without a hearing, in accordance with RRS A5.1.
