Northumberland Strait iceboat

A Northumberland Strait iceboat is a rowing boat, typically 5 metres (16 ft 5 in) in length, 2 metres (6 ft 7 in) in beam, with runners fastened to the hull for dragging over sea ice. == Construction and use == Constructed of wood, similar to fishing dories built in Atlantic Canada and New England, the iceboats were operated in the Northumberland Strait during the 19th century and early 20th century, running between Prince Edward Island and the mainland provinces of New Brunswick and Nova Scotia during the winter months between December and April when sea ice made passage by non-icebreaking steam ships impossible.
