MV Grey Lady is a high speed catamaran ferry operated by Hy-Line Cruises that travels on a route between Hyannis and Nantucket.
The vessel was designed by Incat Crowther and ordered from Gladding-Hearn Shipbuilding in February 2002.[1] While she was originally to be named Grey Lady III, following two previous ferries of that name,[1] when she was delivered in May 2003 she bore the name Grey Lady.[2] She is the third Incat ferry to be operated by Hy-Line, preceded by Grey Lady II (now Lady Martha) and succeeded by Grey Lady IV.[3]
Grey Lady is 144feet long, with a beam of 35feet and a draft of 6.5feet. She displaces 142 Long Tons and is 86 Gross Tons. Her speed comes from four KTA50M2 Cummins diesel engines spinning four Hamilton water jets through Reinjtes gearboxes.[4] The engines can propel her at up to 38kn, though her normal service speed is 31kn. She has a passenger capacity of 300.[1]
