Abstract: An Auxiliary Windshield for a variety of uses, but most specifically for use on a boat, where on occasion, due to weather or speed of operation, added windshield protection is beneficial. A clear plastic shield, which is break resistant, is used with a clamping means which retains the Auxiliary Windshield and by use of a knob can be secured to an existing structure such as an existing windshield. In an alternate embodiment, instead of an Auxiliary Windshield which is clamped in one position, the Auxiliary Windshield may be rotated to various positions. The clamping means includes a fixed arm and a pivot arm, the fixed arm and the pivot arm engaging one another by radial grooves, the pivot arm having the Auxiliary Windshield affixed thereto.
