The Humber sloop Amy Howson was built in 1914 at Joss Scarr's yard at Beverley for George Robert “Cuckoo” Scaife, and first named Sophia, after his wife. The iron hull was built to Sheffield size of sixty one feet six length and fifteen feet six beam, with a hold capable of carrying up to a hundred tons of cargo. Originally rigged as a keel, Sophia worked the  coal trade between the West Riding and Beverley.

Sold to Gouldthorpe, Wright and Scott in 1916, the ship was renamed I Know and rerigged as a sloop by Clapsons of Barton. Initially carrying chalk and stone for the bank protection works on the lower Humber estuary, she later worked the general market and parcel trade between Grimsby and Hull.

Amy Howson was acquired by HKSPS in 1976, undergoing restoration and rerigging over the following five years. She was the first ship to sail under the Humber bridge at its opening.

Now with a Gardner 5LW engine. Amy carries the traditional tan sloop sails. Her fifty five foot mast has a mainsail of 54 feet leech, 29 feet luff, 24 feet head and 34 feet foot and a foresail of 31 feet leech, 28 feet luff and 16 feet foot.

Amy Howson sails regularly through the summer months.
