my sister and I just got certified in scuba diving and decided that we
wanted to start a small business cleaning barnacles off the bottom of
boats while they are still in the water (we heard it was good money).
Unfortunately I'm finding it difficult to locate any instructions on
how to do it underwater. Everything I've come across requires hoisting
the boat out of the water. I know this is a green question but I'm
completely green to the coastal lifestyle. Any help?
