History

Northern Atlantic Dive Expeditions, Inc. was founded in 2000 by Heather Knowles and David Caldwell with the intent of promoting shipwreck exploration in New England.

Heather and adveFrom 2000-2004, Heather and Dave organized and led charters aboard other vessels, focusing on local Massachusetts Bay diving, as well as larger trips to shipwrecks such as the Empress of Ireland, Andrea Doria, and U-869. During this time, Heather and Dave planned to acquire a boat, and ultimately decided to build one.

Mission Statement 

Northern Atlantic Dive Expeditions, Inc. is dedicated to shipwreck research, discovery and exploration in New England, as well as conservation of the ocean environment and our shipwrecks. NADE is committed to:

  • Offering dive charters to facilitate sport diving in Massachusetts Bay and the Gulf of Maine
  • Undertaking shipwreck research
  • Pursuing shipwreck exploration and discovery
  • Training and mentoring skilled, knowledgeable and safe divers

In 2004, NADE launched GAUNTLET, a custom-built Northern Bay 36 downeast style boat, constructed specifically for diving. GAUNTLET enabled NADE to expand the business, offering more charters, the potential to conduct research and exploration, and offer technical diving training.

GAUNTLET became a platform for research and exploration in addition to sport diving charters. NADE has supported research projects during the LNG terminal construction, conducted surveys of sunken vessels for insurance companies, and worked with academic researchers studying the marine environment.

NADE expanded it’s own work in shipwreck discovery and exploration with GAUNTLET, and discovered several notable, historic shipwrecks along the way. With over 800 dive charters run aboard GAUNTLET, Heather and Dave have brought many divers on thrilling adventures, promoting diving, and leading excursions into our maritime history.
