The motor yacht (m/y) Grey Pearl is owned and operated by US Coast Guard Captains Martina and Braun Jones. She is a small boat of the 'Adventure' or 'Expedition' yacht class, designed and built for worldwide cruising. She is currently on a leisurely circumnavigation of the world.

Thus far, beginning in 2000 she has taken her owners from the Canadian Maritimes south along the East Coast of the USA, deep into the Bahamas, and across the Atlantic, with three years spent exploring the Mediterranean, including the far eastern portion and the countries of Cyprus, Syria, Lebanon, Israel and Egypt. After returning from the Mediterranean to the USA, in 2008 she departed from Annapolis, Maryland, bore south along Central America, transited the Panama Canal and made for Seattle. That summer was spent cruising throughout British Columbia and the winter of 2009 she berthed in Seattle.

In the spring of 2009, she set sail on the Great Siberian Sushi Run (GSSR) - a  transpacific voyage from Seattle to British Columbia to Alaska to the Aleutians to Russia and ending August 2009 in Osaka, Japan.
The winter of 2009/10 was spent in Osaka, and in April 2010 the Pearl set sail for Japan's Inland Sea, the Ryukyu Islands, Okinawa, Taiwan, and eventually reached Hong Kong where she is berthed for the winter 2010/11.

In the spring of 2011 the Pearl sailed from Hong Kong across the South China Sea and leisurely through the Philippines. She eventually reached Kota Kinabalu Borneo, Malaysia. 

In October and November, 2011 she sailed from Kota Kinabalu to Singapore and on through the Malacca Strait to Phuket, Thailand where she will spend the winter of 2012. 

Future plans are to cross the Indian Ocean and then north through the Red Sea to the Mediterranean. However the piracy situation in the Gulf of Aden and adjacent waters is being closely monitored and plans may have to be adjusted accordingly.
