Humber keel

The Humber Keel was a type of sail craft used for inshore and inland cargo transport around Hull and the River Humber, in the United Kingdom, through the late 19th and early 20th centuries.

The dimensions of these craft influenced the guage, or width, of inland waterways created or modernised during that period. In comparison to the widespread use of the Narrowboat standard, far fewer inland waterways were designed to accommodate the larger Humber Keel gauge vessels. This standard is still used on associated waterways today.
