Abstract: An aquatic sport device includes a buoyant board configured for supporting a user in a prone position thereon and sized to enable the user supported thereby to manually paddle while in a prone position in order to move the buoyant board through the water. A sight opening is provided through the buoyant board in an optical system disposed therein enables a visual perception through the buoyant board by the user when the user is in a prone position. The optical system is configured for enabling the user to look through the board and perceive in a forward direction towards the bow of the buoyant board while paddling.
