Unfortunately that's how the supply chain with boats works. When the boat was manufactured, the manufacturer would do something along the lines of build 100 boats and order 105 windshields from a windshield manufacturer, such as Taylor Made with the extra 5 accounting for windshields that may be damaged on boats in transport to the dealer. After that, they don't care what happens. If it breaks, it's an insurance problem if you have insurance. On the flip side, there isn't much of a market for windshields for 20 foot stingray boats, so if you found one, offer them half and see if they bite. It's almost guaranteed they will counter offer and you may meet up in the middle.
