Note 442 — Chapter XV
Reading edition
The dimensions of the Iona are 250 feet in length and 25 feet breadth of beam. She is propelled by a pair of oscillating engines, with a combined nominal power of 180 horses. Her draught of water, when fully laden, does not exceed 6 feet, and her speed under favourable circumstances is from 20 to 21 statute miles per hour. She is the fastest vessel in Great Britain, or perhaps in the world, one or two of the steamers of the United States excepted.
