Bearings in magnetic true. Variation 1.1° W at 53° 25.04′ N 006° 03.96′ W on 1 October 2026, from the World Magnetic Model (WMM-2025): magnetic is true plus 1.1°. Bearings are computed from the marks' positions, so are true; magnetic is worked from the unrounded true bearing.

Finish

FH	Finish line	53° 23.60′ N 006° 03.92′ W

Every course on this card continues past its last printed mark: Q → HM → FH. The card prints none of it. HYC Autumn League 2026 sailing instructions 6.1 D.

For all Round the Cans Races (unless the course is shortened) the finish will be on the HYC finish line in Howth Sound. After passing the last mark on the displayed course (either K or G), boats shall sail to the finish line passing the Rowan Rocks Buoy and the Howth Mark (both IALA marks) to starboard. The finish line is between a vertical line on the front of the Finisher’s Hut and a Black cherry bouy.. This changes RRS , Race Signals. The Finisher’s Hut is located on the East Pier approximately 100m east of the old lighthouse.

Card notes

1. The colour and style (underlined or not) of the mark reference letter displayed above indicates the required side that the mark is to be left. RED indicates leave to port, GREEN to starboard. Whether marks are to be rounded or passed is determined by the course required to sail from the mark preceding the mark in question to the one after it. Marks are to be left (rounded or passed) in the sequence listed. Where an objective assessment of the course design and listed mark sequence indicates a requirement to round a mark, rather than passing it (thereby reducing the number of legs sailed), it shall be deemed a rounding mark.

2. The finishing line for Round The Cans Courses shall,unless a race is shortened, be between a vertical line on the front of the East Pier Finisher Hut & a black cherry buoy.
