    摘要: A compartment includes a first broad panel adapted to cover a first side of a body board, and a second broad panel adapted to cover a second side of the body board. The first broad panel includes an elastic lined first lip at a distal end of the first broad panel, and the second broad panel includes an elastic lined second lip at a distal end of the second broad panel. The lips form a boundary of an opening adapted for the body board to be inserted there-through and into the compartment. The first broad panel is adapted to extend over a distal end of the body board so that the first lip is positioned on the second side of the body board, and the second broad panel is adapted to extend over the distal end of the body board so that the second lip is positioned on the first side of the body board. An accessory compartment is attached to the second broad panel. The accessory compartment includes structure forming an elongated accessory compartment opening. The accessory compartment opening is positioned generally in a center of the accessory compartment, and divides the accessory compartment into two sections. The accessory compartment is adapted to retain at least two swim fins therein, at least one of the swim fins in each of the sections. The accessory compartment opening is bounded by two elastic lined elongated edges, whereby the swim fins are securely retainable within the sections.
