In “The Sea Chart” replace “a Fishing Contestant can move their name from their current cell to a cell no greater than four orthogonally connected cells away from their current cell” with “a Fishing Contestant can move their name from their current cell to a new cell, provided Manhattan distance (i.e. the number of orthogonal steps needed to get from one cell to another) between those two cells is not greater than their current speed”

Add the following to “Fishing Contestant”

Each Fishing Contestant has a Speed which is publicly tracked

If a Fishing Contestant has between 0 and 15 Catches, their Speed is 4
If a Fishing Contestant has between 16 and 30 Catches, their Speed is 3
If a Fishing Contestant has between 31 and 45 Catches, their Speed is 2
If a Fishing Contestant has more than 45 Catches, their Speed is 1
