      "why": "A4.3 is what puts a course card in use: flag X ashore on a Saturday sends every keelboat class but the Green fleet to the West Pier hut, under supplement H and Course Card 2. A10.4 restricts passing between the hut and the start limit marks."

      "why": "H4.1 and H4.2 define the West Pier hut starting line that cards 2 and 5 start at — a fixed transit, not a laid line — and H4.3 the limit mark; H5.5 says which card is used on which day; H5.6 makes Turning mark X a passing mark; H6.1 the finish, also at the hut."

      "why": "Adds B4.3: if the committee vessel cannot anchor, the starting line may be between two marks, or a mark and a RIB. It is an alternative to B4.2, not a replacement, so the card’s start line quotes B4.2."
