Pacific white-sided dolphins have a “good” habit of enjoying playing with a boat. Slowing a boat to 7 or 8 mph seems to provide a reason for this change in behaviour. The dolphins will pace the boat, nose into the prop wash of the motor and even ride the bow wave. They will often play for fifteen or twenty minutes then abruptly stop and go their way, This is the signal they have had enough and it is time to hunt for food.
