Add a new rule named “The Sea Chart” with the following text:

There is a publicly-tracked grid, named “The Sea Chart”, which consists of Cells where each Cell is labeled with the letters “A” through “G” in alphabetical order across the columns of the grid, and the numbers 1 through 8 in numerical order down the rows of the grid. A specific Cell is referenced by its column letter and its row number in that order, e.g. D4 for the Cell in the column labeled D and the row labeled 4. Each Cell may contain the names of 0 or more Fishing Contestants.

If a Fishing Contestant’s name is not in any Cell, the Elder Judge should randomly select a Cell by column letter and row number, repeating this random selection until an empty Cell is selected, and then add that Fishing Contestant’s name to that Cell.
