Abstract

Abstract A boat for scuba divers and the like having a well whose walls extend from the bottom hull to a position above the water line. The well is enclosed by a hinged cover at its upper portion and a closure member pivoted at one end and shaped to conform with the bottom hull. Mounted on the inner surface of the closure member is a plurality of steps mounted thereon at such an angle that when the closure member is in its open position, the steps will be in a horizontal position permitting a person to walk down the well and into the water. A handle is secured to the free end of the closure member to assist in opening and closing the closure member and locking same in place. A self boiling flap valve is positioned at the free end of the closure member whereby water trapped in the well, is suctioned out of the well as the boat is driven forwardly.
