⚓ In September 1823, a new dockyard opened at Sheerness. It had taken ten years and cost more than two and a half million pounds — about the price of twenty-nine brand-new first-rates. The navy chose to spend that money on stone basins, granite docks and pumps. On holes in the ground.

This video explains why. Most of a warship is underwater, out of reach, and everything that decides her speed and life happens there. We look at careening and the tidal grid, Edmund Dummer’s first stepped stone docks of the 1690s, and why the steps — the altars — mattered so much. Then the machinery: tides, sluices, horse-driven pumps and a calendar set by the moon, and the risky business of setting a ship down on her keel blocks.

The docks were the bottleneck behind everything, from coppering the fleet to repairing it after battle. We follow Samuel Bentham’s first steam engine in a royal dockyard, and John Rennie’s granite rebuilding — including a yard that had been standing on the rotting hulks of old ships.

📜 What is known and what is reconstruction Dates, dock histories, the Sheerness costs and Bentham’s steam engines come from the published research listed below. The comparison with “twenty-nine first-rates” is our own arithmetic, dividing the Sheerness cost by the building cost of the Queen Charlotte.
