At one time, men and women took their lives in their hands when they used boats to catch fish, save lives or land cargo. Nowadays, extreme rowing is an Adrenalin-fuelled activity used to test the nerves and self-belief and is pursued as a hobby or sport. Extreme rowing includes long-distance racing, surf rowing, ice boating and individual adventure, all of which require supreme mental and physical toughness. As well as testing human endeavour, the boat design and materials also have to live up to the challenge.
