 Thomas Crisp was born into a family of shipwrights and fishermen in Lowestoft, one of ten children to William and Mary Anne Crisp. Although his father was the owner of a successful boatbuilding firm and thus could afford an education for his children, Thomas did not enjoy school, instead showing a "marked preference for quayside adventure to school routine". Leaving school, Thomas took to the sea, spending several years as a herring fisherman before joining a fishing trawler out of Lowestoft. He was a natural to the work, being a remarkably good sailor, but tired of it quickly and joined the Atlantic steamship SS Mobile, becoming her quartermaster and making several trans – Atlantic voyages.
