I have a 1991 Bayliner Trophy Hardtop (not walk-around). Its the weather over here, need more airflow through the hardtop area, especially at anchor.<br /><br />Looking at removing the middle glass pane to modify the frame to allow opening. Need to figure out how to remove it.<br /><br />Noticed 2 screws at the top edge, there is a row of nuts visible from the cabin interior. These appear to be holding the lower edge of the frame.<br /><br />Question 1. Will removing the 2 uppers screw be enough?<br /><br />Question 2. Has any one done similar modification to get more air through?<br /><br />Thanks.
