Abstract: There is described a ventilation system for a boat. The windshield body comprises an air scoop in a bottom portion of the windshield body, facing a forward direction of the boat for air entry, the air scoop having an entry which is substantially horizontal and the air scoop extending upwardly within the windshield body to form a conduit having an upward component. The conduit end opens toward an inside of the boat, at a location higher than the entry of the air scoop. A hingeable vent can be installed on the opening inside the boat to be open or closed. The vent may also be sued with a direct opening with the outside. In this case, flaps can be installed in the opening. The flaps can be hingeable about their own respective hinge axis, and move together using a solid link. The flaps may be used without the vent.

Abstract: A method for manufacturing a boat windshield comprising providing a piece of glass of an arbitrary shape to form a portion of a boat windshield; and providing a mold or cast defining a cavity for molding or casting an appropriate material therein. The cavity defines a shape of a frame to be molded or cast and having a shape complementary to a contour of the corresponding piece of glass having the arbitrary shape, said frame having otherwise an arbitrary frame shape including variable cross-section, width or thickness along a length thereof; or it can longitudinally extend in a curved manner. After molding or casting said frame (alternatively: additive manufacturing), together with functional features, said frame is secured to the corresponding piece of glass or encapsulating the corresponding piece of glass into said frame having been molded or cast, forming a sub-frame assembly being a panel of the boat windshield.
