PRESENTER: A deaf teacher from Scotland is on a personal quest to prove the naysayers wrong. He is sailing solo around the world, a dream he has had for more than 40 years. The journey hasn't quite been smooth sailing. The adventurer finds himself in Hobart for some repairs to his yacht.
REPORTER LUCY SHANNON: Gerry Hughes wasn't expecting to be on dry land so soon but a freak wave in the Southern Ocean has meant a change of plans.
GERRY HUGHES (via translator): And suddenly, everything was upside down. The whole boat had capsized. All the floorboards had actually lifted off of the floor.
REPORTER LUCY SHANNON: The yacht righted itself but its auto-pilot and two computers were wrecked. Despite the terrifying experience, the sailor is itching to head back out to sea.
GERRY HUGHES (via translator): Yes, a definite passion, a definite passion. It's in my heart. I've waited for 40 years to do this challenge... when I was young.
REPORTER LUCY SHANNON: The first major hurdle he faced wasn't learning to trim the sails, it was learning to read and write. He achieved that at age 15. Ever since then, he has taken on solo sailing adventures, culminating in this, his trip of a lifetime.
GERRY HUGHES (via translator): There are a lot of deaf people like me that have very low self-esteem, low confidence. A lot of hearing people always say, "Oh deaf people can't do this. Oh you can't .... that's too difficult for you. You can't do this, you can't do that."
REPORTER LUCY SHANNON: Thousands of deaf people all over the world are following his journey on his web and Facebook pages and he has made an impression since being in Hobart.
NOEL RICHARDSON (Marina Manager): He's a very brave person and a very likeable person and I wish him all success in his promotion of the deaf community around the world.
REPORTER LUCY SHANNON: With computers up and running he is able to chat with his wife once more. Talk is of Cape Horn and the possibility of icebergs. Lucy Shannon, ABC News.
