If I choose to use the ability of the English Native canoes (below), would I have to apply it to all of them in the set, or however many I chose, since all of the canoes are technically being given a move action.
Give this ship a move action but do not move her. Instead, roll a d6. On a result of 5 or 6, you may repair one mast on ships within S of any native canoes.
“Move” is the action given, but what each canoe does with that move action is up to you. Some can move while others make repairs.
Note that the way it’s worded, the roll/attempt is what replaces the movement, so if that roll fails, the canoe cannot move instead.
