Like many vehicles, high-speed boats have windshields to keep outside elements away from the driver. If the windshield on your boat becomes loose, broken or otherwise incapable of performing its task, you may wish to replace it. While there are many manufacturers that provide replacement windshields and frames, you may prefer to make your own windshield frame.
Determine the measurements for your frame. Measure the width to cover the driver's station and passenger seat. Figure out the height you want the windshield to rise above the dashboard. Normally a boat windshield is between 45 and 60 cm (18 and 24 inches)tall.
Create the windshield frame with 2.5 cm by 6 mm (1 inch by 1/4 inch) aluminium. Cut two pieces of aluminium, using a mitre saw, to the length of the windshield and another two to the height.
Organise the pieces into the shape of a rectangular frame.
Create corner brackets with 2.5 cm by 3 mm (1 inch by 1/8 inch) aluminium strips. Cut four pieces to 5 cm (2 inches) in length.
Place a bracket on each corner so that the bracket extends onto the sides of the frame.
Attach the brackets to the frame using 6 mm (1/4 inch) screws.
