Born and raised on Cape Cod, Massachusetts Sean was given his first sail boat, a Laser, at 8 years old. By 12 he graduated to a 13-foot Boston Whaler. By 18 he earned his first Captains ticket and became the youngest Captain ever at Hyline Cruises (a local ferry company providing service from Cape Cod to Nantucket and Martha’s Vineyard).

From the ice fields of Northwest Passage and North pole to the volcanoes and jungles of the South Pacific and South East Asia. Captain Meagher has piloted some of the world’s finest sail and power vessels in the most remote areas on the planet.

On the MY Latitude, he undertook 3 historic journeys. In 2014 He led Latitude, a robust though non iceclassed design by Vripack, through the Northwest passage (east to west) and was the 216 th boat in history to do so. Norwegian explorer Roald Amundsen was the first in 1906. In 2015 Captain Meagher led a second expedition through the passage this time west to east was the 9 th boat in history to ever do so and was awarded Boat Internationals Voyager Award.

A glutton for punishment in 2016 Latitude ventured North once again. This time circumnavigating Svalbard, an archipelago north of Norway, and punching within 400 miles of the North pole. Latitude is the only private vessel ever to do this and was nominated for second Boat International Voyager Award.

In 2017 Latitude headed to New Zealand where she underwent an extensive refit. Captain Meagher was the lead designer and Latitude was nominated along with Vripack for a third Boat International award.

This time in the “Best Refit” category.

After New Zealand Captain Meagher returned to his old stomping grounds of the South Pacific and South East Asia. Here he sadly said good bye to Latitude completing a five-year mission to go on adventures and photograph wildlife.

A life long conservationist Captain Meagher has noticed a disturbing trend in the amount of plastics in the Oceans. Ever proactive he has allied himself with organizations such as The Ocean Voyages Institute and has spoken internationally on the subject of plastics in the Ocean and what to do with them.

Sean’s latest command was as delivery Captain for a brand new 357 foot yacht built by Oceanco. Captain Meagher holds a USCG Master’s Unlimited Tonnage all oceans license for both sail and power.

Exploration Interests

My exploration interests are many and varied.

I would like to lead another exploration via ship to Svalbard and to “ice in” for the winter using the opportunity to study and photograph polar bears. While charting some of the more remote areas of the archipelago.

I am currently involved with Ocean Voyages and their quest for a plastic free ocean. I have spoken all over the world on the topic and have photographed plastic in some of the worlds most remote areas.

Finally in addition to exploring the physical world first hand I have been involved with developing and exploring new technologies and the new application of technologies. Everything from non toxic coatings for hulls and pipe works to the harnessing of Hydrogen for fuel.
