full boat n. a full price or total amount of money; generally, all of something; as an adj., having many or elaborate features, options, or functions. Editorial Note: Often constructed as to pay full boat or with the definite article: the full boat. In yoga and exercise there is a pose also called the full boat, which is probably unrelated. Etymological Note: Perhaps influenced by a full boat ‘full house’ in poker, representing three of one kind and two of another. (source: Double-Tongued Dictionary)
