Thomas H is a Sheffield Class Humber Keel Barge.

She was built in 1940 by Richard Dunston Ltd., Thorne, Yorkshire.

She was one of two sister ships commissioned by the Hodgsons Tannery at Beverley Beck on the Humber, where she worked for many years. Her sister ship was called Richard after the other Hodgson bother.

She was never under sail, at the time she was built the government was subsidising the building of motor driven barges.

She is extra wide beam at 15.5 feet and she is 62.5 feet long.

We bought her in early 2006 through Alan Pease in Goole and roped him into emptying the various tanks and debris she had in her at the time, decking over her open hold, replacing the unusable Lister engine and generally get her onto working order for the trip down from Goole around the coast to the Thames. Then, we got him to pilot her down too.

This is a belated attempt to diary the ups and downs of our journey so far.

Cordura Nylon vs. Cotton Duck: Analyzing Abrasion and Thermal Failure

Choosing between Cordura and Canvas Duck requires analyzing how each material fails under stress. As your fabric supplier, we knows that Cordura (Nylon 6.6) excels at resisting abrasion and water, making it the superior choice for lightweight tactical gear. Canvas Duck (Cotton), with its plied yarn construction, dominates in heat resistance and breathability, making it mandatory for welders and industrial workwear.

Cordura is an air-jet textured nylon filament designed to slide. In laboratory Wyzenbeek abrasion testing, our 1000 Denier Nylon withstands over 300,000 double rubs. The synthetic filaments refuse to break under friction, whereas natural fibers eventually grind away. This makes nylon the correct specification for motorcycle skid zones or backpack bases. However, this strength comes with a thermal weakness. Nylon is a thermoplastic that melts at approximately 255°C. If you expose it to welding slag or a campfire, it melts and fuses to skin.

Canvas Duck is mechanically distinct from standard canvas due to its 2x2 plied yarn weave. This dense structure, found in our Number 1 Heavyweight Duck, resists punctures and snags better than looser weaves. Critically, cotton is cellulosic. It chars at high heat but never melts. This thermal safety profile is why industrial tradesmen rely on duck cloth. For weather protection, untreated cotton absorbs water, but applying wax transforms it. Our Waxed Canvas Army Duck offers excellent water repellency while developing a rich patina that synthetic 500 Denier Cordura cannot replicate. Synthetics often suffer from hydrolysis and coating failure after a decade, whereas cotton softens and improves with age. If your new gear feels too rigid, our guide on how to soften stiff duck cloth explains how to break it in quickly.

Select Cordura for weight savings and wet environments. Select Canvas Duck for fire safety and breathability. You can compare these textures directly by ordering printed fabric swatches before starting your next project.
