Scuba Addicts was set up by husband-and-wife team Graham and Anne Ferguson in the summer of 2009, initially on a whim after both lost their jobs when the credit crunch bit down hard.
Using their redundancy packages and a grant from the West Coast Development Partnership, they were able to purchase the boat they now use to take diving enthusiasts offshore.
And business is booming, with some 300 divers using their service in 2011 alone to explore coastal shipwrecks such as the infamous gun-running ship The Aud and the recently discovered German U-boat in Cork Harbour.
"We are making a big drive into Dutch, Belgian and German markets this year," says Anne. "There is huge potential for dive tourism from this area."
