Yeah, here's my biggest concern on this boat - Barnacles. Wet barnacles fresh out of the water, are easy enough to scrape. However, the base that is adhered to the bottom will be left behind.
The question is, how does one remove just the thin round base? Remember that the glue these little buggers use is stronger than cyanocacrylate.
I remember in my youth, researchers were trying to figure out how to synthesize barnacle glue, because it's just that strong. I wonder where that ever went? Time to break out the google!
Hey, wow, check out this BBC article from 2009:
