Ice Boat - A small boat typically used on P.E.I. for transportation across the Northumberland Strait prior to 1918 during the Winter Months. Typically, they were 5 metres long, and 1.2 metres wide, and were covered with tin to protect the vessel from the ice. Often they had metal runners on the sides of the keel.They were outfitted with sails and oars, and could be rowed or paddle across the Strait. When the ice grew too thick, the crew and male passengers in exchange for a lower rate, would pull the boat across the ice. The vessel was equipped with leather harnesses to attach the crew to the vessel while pulling, also protecting them from drowning when the ice gave away.
