Eskimo boats, also known as umiaks (6 letters), are traditional watercraft used by the Inuit and Yupik people of the Arctic regions. They are large open boats, typically made from driftwood or whalebone, and covered with animal skins. Umiaks are used for transportation, hunting, and fishing, and can carry up to 10 passengers. They are propelled by paddles or sails, and are capable of navigating through ice-filled waters.
