An exceptional pronunciation is in "knowledge" and "rowlock". For a oar the balance point is about 12 inches outboard of the rowlock. She was renamed SS "Rowlock" and continued in commercial service until 1950. Both the doors and windows have two rowlock brick arches over them. Two headers of brock are placed above the windows to form rowlock arches. Sometimes on narrow, faster rowboats for protected waters outriggers are added to increase rowlock separation. There are three rowlock arches above all of the windows on the first floor.
