Abstract: A tackle container assembly mountable below a deck-mounted pedestal seat, including an upper principal member secured to the lower surface of the seat and means depending therefrom to support one or more containers in positions spaced well above the deck, such that fishing tackle can be readily accessible to a fisherman without interfering with or limiting the position of his feet beneath the seat or his hands and arms during fishing movements. Preferred embodiments include a slotted arrangement and/or spacers to allow good utilization of as much space beneath the pedestal seat.
