Abstract: An apparatus for viewing marine life is disclosed. The apparatus includes a board configured to float on water and a window positioned in an opening in the board. The opening in a front end of the board and the window includes a transparent top portion, a transparent bottom pane and sides forming a center void. The window is sealed to prevent water from entering the void and the window includes a bottom lip planar with the transparent bottom pane. The apparatus includes a seal positioned in a gap between the window and the opening in the board and above the lip. The seal is inserted from a top surface of the board and provides a friction fit between the window and the opening. The seal includes a flexible resilient material and sized for a friction fit between the opening and the window to prevent movement of the window.
