Mayflower Autonomous Researcher Ship (MARS)

The Mayflower

ProMare is a key partner in the development of the world’s first full-sized, fully autonomous unmanned research ship. The vessel will take the same 3220 mile route the original Mayflower used 400 years ago. It will only use wind and solar technology for the journey, and will also gather data about the condition of the ocean.



In order to explore the deepest parts of the world’s oceans, ProMare has funded the development of a low-cost, full-ocean-depth robotic vehicle system. The prototype was used to explore the deepest parts of the Atlantic Ocean, the Puerto Rico Trench, more than 8000 meters deep.

Protection of manatees and their aquatic habitat

ProMare supports the world’s leading manatee conservation organization, Save the Manatee Club, in their efforts to protect manatees and their aquatic habitat for future generations. We have adopted a manatee, appropriately named Promanatee, and visited the charity located in Florida, in 2018. More information about their activities can be found here.

Malta – Xlendi Shipwreck Video

In July 2001 ProMare conducted an ROV survey in Malta in cooperation with INA and the Malta National Museum of Archaeology. INA began a systematic survey of the Maltese archipelago in the fall of 1999, under the direction of Ayse Atauz.  The work in 2001 constituted the first deepwater survey in Malta.
