First time poster so I guess I'd better introduce myself as I can definitely imagine annoying you all with loads of questions in the coming weeks... sorry in advance. I'm an RYA PBI and have always been much more on-the-user and general upkeep-of-boats so this is my first proper foray into the dirty side of powerboating
So, I'm getting my University's SubAqua Club's RIB back up to scratch after it was left on a mooring for over a year gathering dust, sealife and rainwater (transom was about 3 inches below the waterline
So far I've managed to remove the fish and crabs from inside the boat, and scraped the barnacle shells from the bottom (going to remove the barnacle 'feet' remaining with diluted HCl and sponges) but, as the boat was weighed down so much, the back 1/2 of the sponsons were submerged and are coated in barnacles... any suggestions at all as to how to get rid of them without damaging the hypalon?
Cheers in advance,
