Abstract
Watercraft has a hull with a viewing opening therein extending between upper and lower portions of the hull. A transparent viewing unit is fitted within the viewing opening and has a periphery spaced apart from side wall of the viewing opening to define a draining space between the side wall and the viewing unit. This provides a peripheral clearance extending generally around the unit for draining water through the hull irrespective of angle of the watercraft with respect to the horizontal. A cowl extends peripherally around the viewing opening and has a lower portion sealing the viewing opening to prevent passage of water, and an upper portion to embrace portions of a person's face to exclude extraneous light.
