No, not the square-rigger that brought Pilgrims to America, but the Mayflower Autonomous Research Ship (MARS). Plans call for the wind- and solar-powered trimaran to sail itself from Plymouth, England to Plymouth, Massachusetts in 2020 – the 400th anniversary of the original ship's journey – carrying out a variety of research projects along the way.

The ship is the focus of Project MARS, a collaborative effort involving Plymouth University, autonomous craft specialist MSubs and yacht manufacturer Shuttleworth Design.

It will be 32.5 meters long and 16.8 meters across (106.6 x 55.1 ft), with a glass/aramid/foam composite hull and a carbon composite deck. Using either or both of its two sails, MARS will be able to move at a speed of up to 20 knots (37 km/h or 23 mph). On less breezy days when the sails are automatically stowed belowdeck, its solar-powered electric motor will still take it up to 12.5 knots (23 km/h or 14 mph). The solar cells should be able to generate enough current that if traveling at 5 knots (9 km/h or 6 mph) under motor power, the ship's range will be unlimited. Some of those cells will be on a folding wing, that will only open under calm sea conditions.
