Lassie

Troubled Waters (17x20)

Air date: Feb 21, 1971

Lassie and her new pal, a mutt named Skipper, are getting along just fine with Reed and Johnny, a couple of guys they befriended on the beach, until John discovers Reed is "the law," a harbormaster, and walks out. But he finds he needs "the law" later on when he "borrows" a for-sale cabin cruiser and takes Lassie and Skipper along for the ride.
