If you're traveling the Atlantic and you come across a ship without a crew, it won't be the Flying Dutchman. It will be called the Mayflower, and it will be an autonomous research ship (Mayflower Autonomous Research Ship or MARS). 
Currently, Mayflower is reportedly being in plans from Plymouth University (it will use wind and solar energy) and probably will fly from Plymouth, England, to 2020. Let's say the researchers are still looking for funding.
Using one or both of its sails, the Mayflower will be able to propel itselfname with a speed of up to 20 knots (37 km/h). Its length will be 32,5 meters.
On days when there is no wind, it will move with its electric engine and it will hit 12,5 knots (23 km / h).
The solar cells will be able to produce enough current to be more than enough. Some of these cells will be in a collapsible wing, which will only open under conditions of absolute lull.
Navigation will be through a system that combines GPS technology with a collision avoidance technology.
According to the design company MSubs:
"The aim is to build one or more payload areas, like a space shuttle, on which a wide range of equipment will be placed to support various research projects."
"Equally important, we conduct research on renewable energy sources and propulsion systems for marine vessels, research on a software with automated and autonomous functions, advanced satellite communications, and cooperative behavior between nested automated and autonomous systems that will operate under, and above water simultaneously.”
