I have an 87 Ranger 393V that is in great condition thanks to my Father. ;D He kept it stored in the basement/garage and pampered it, even though he fished it hard. I want to replace the bunk boards and carpet. I was thinking about buying some bunk glides to install. This old boat is heavy and would be easier to load with the bunk glides. I am worried about the fiberglass resting on the glides for any long amount of time. :-/ Does anyone have any suggestions? ???
