      "transcribed": true,
      "why": "10.1 has the race committee set each course on the day from the fixed marks, the islands and the Fastnet Rock and display it on the committee boat, which is why the card carries no courses; 9.1 gives the racing area and where races start and finish; 11.1 says a chart of the permanently laid marks is issued at registration; 12.1 defines the start line and 13.1 the finishing line the card carries. The PDF on the official notice board (posted 20 July 2026) is a scan with no text layer, so its sidecar is transcribed by hand and kept rather than generated; the start line, the finish and the notes are read from the transcript."

      "why": "The chart SI 11.1 promises: the marks over an Admiralty chart of Long Island Bay, with the index that letters the six fixed marks — the ids the marks file uses — and, on its second page, the three navigation marks photographed with their positions, which cross-check the sheet's."

The positions themselves are borne out to the minute by the chartlet and the buoy photos, so the table is the weaker statement. It is held here to 15° and 0.5 NM, and the nineteen pairs beyond that are listed with what the sheet prints and what its positions give: where the reciprocal cell agrees with the positions the cell is a slip, and where both directions miss the pair was worked from other positions.",
