Anti-foul in fresh water?

I’m still confused about the necessity for regular hull cleanings and air-foul reapplications in FRESH WATER. All I can see is a thin layer of algae. In theory that might have some minuscule effect on performance through the water, but in a big tub of a trawler like mine, I doubt that’s significant. So what else? Can algae impact the integrity of the fiberglass hull? At what point does it become too much, too long?
