Refit and First Copper Sheathing Portsmouth, March 1780
The introduction of copper sheathing was one of the most significant technical innovations of the British Navy in the late 18th century. HMS Victory was fitted with copper sheathing during a major refit in Portsmouth between 1778 and 1780 as part of the Royal Navy’s preparations for the American War of Independence.[2]
Background: Why copper?
In the 18th century, wooden ships suffered from two serious problems: fouling of the hull by marine organisms and infestation by shipworm (Teredo navalis). Trials conducted by the Royal Navy showed that copper plating significantly reduced both problems. The frigate HMS Alarm was copper-plated in 1761, and by 1783, copper plating had become standard on important Royal Navy warships.[2]
The copper plating of HMS Victory, 1778-1780
After years in reserve, HMS Victory was in poor condition. During an extensive refit at Portsmouth (1778-1780), the ship was almost completely refurbished, including new copper plating below the waterline.[3] The plating consisted of approximately 3923 copper plates (4 feet long × 14 inches wide), fastened with copper nails to prevent galvanic corrosion.
Technical problems and solutions:
Initial copper plating attempts caused electrochemical reactions with iron bolts, accelerating corrosion. The solution was using copper bolts and corrosion-resistant fastenings.[4] The current conservation project has documented numerous original copper bolts below the waterline, some up to three meters long.[4]
Armament at Trafalgar 1805
The armament of HMS Victory according to the Royal Navy and the current HMS Victory Project in Portsmouth. According to these sources, her armament at the Battle of Trafalgar on 21 October 1805 consisted of exactly 104 guns:
| Deck | Type of Gun | Number |
|---|---|---|
| Lower Gun Deck | 32-pounder Long Gun (Blomefield) | 30 |
| Middle Gun Deck | 24-pounder Long Gun | 28 |
| Upper Gun Deck | 12-pounder Short Gun | 30 |
| Quarterdeck | 12-pounder Short Gun | 12 |
| Forecastle | 12-pounder Medium Gun | 2 |
| Forecastle | 68-pounder Carronade | 2 |
| Total | 104 |
A broadside fired approximately 540 kg of iron shot. The 68-pounder carronades were particularly feared for their devastating effect at close range.
The Carronades – The “Secret Weapon” at Close Range
The 2 × 68-pounder carronades were the special feature of Victory’s armament:
- Short, thick barrel:
- Length: ~1.5-2 meters (vs. 3-4m for long guns)
- Caliber: 68 pounds (~31 kg shells) – nearly twice as heavy as 32-pounders
- Gun weight: ~1,000-1,200 kg (vs. 2,000-3,000 kg for long guns)
- Advantages:
- Extremely destructive at close range (<500 yards): could penetrate entire decks or tear open ship sides
- Effective against crews (grapeshot) or masts/rigging (chain shot)
- Faster reloading: smaller crew (4-5 men) and higher rate of fire (shot every 2-3 minutes)
- More stable at sea: shorter barrel meant less recoil and sway
- Disadvantages:
- Short range (effective only up to ~400-500 yards)
- Inaccurate at long range – suitable only for close combat
- Use at Trafalgar:
- Nelson used carronades deliberately in close combat when Victory came alongside enemy ships
- Their devastating effect contributed significantly to the victory
Long Guns – Precision at a Distance
| Type | Shell Weight | Range | Purpose |
|---|---|---|---|
| 32-pounders | 31 kg | ~2,000 yards (~1,800 m) | Penetrating ship sides |
| 24-pounders | 24 kg | ~1,800 yards (~1,600 m) | Medium range |
| 12-pounders | 12 kg | ~1,500 yards (~1,350 m) | Upper deck (against masts/rigging) |
This Combination Made the Victory Unbeatable
| Factor | Long Guns | Carronades | Overall Effect |
|---|---|---|---|
| Range | long range | short range | Flexibility - effective at all distances |
| Destructive Power | high | very high | Maximum effect in close combat |
| Rate of Fire | moderate | very fast | Fast, concentrated fire |
| Use | Long-range combat | Close combat | Tactical advantage |

Anchors
Purpose of the various anchors:
The bower anchors (port and starboard) served as main anchors for secure mooring in deep water or strong winds.
The sheet anchor was a reserve for emergencies.
The Kedge Anchor was used for precise maneuvers, while the Stream Anchor was for temporary mooring in shallow waters.

The Anchor Cables of HMS Victory (1805)
Dimensions, Manufacture and Places of Production
Introduction
As a First Rate ship carrying 100 guns, HMS Victory was equipped with principal anchors and their associated anchor cables according to Admiralty Establishments. These were among the largest and most technically demanding ropeworks for the Royal Navy.[12]Construction of Anchor Cables
The anchor cables were manufactured from high-quality hemp as heavy cable-laid ropes, consisting of three substantial strands laid in the opposite direction to the yarns. This construction provided strength, elasticity, and resistance to shock loading. After manufacture, cables were treated with Stockholm tar to prevent moisture damage.Dimensions of the Principal Anchor Cables
Admiralty Establishments for First Rate ships specified:| Item | Measurement |
|---|---|
| Circumference | 24 inches |
| Diameter | ~7.64 inches (19.4 cm) |
| Length | 100 fathoms (~183 meters/600 feet) |
| Material | Hemp |
| Construction | Three-strand cable-laid rope |
A cable of this size weighed several tons and required specialized equipment and considerable manpower for handling.
Manufacture
Anchor cable manufacture was carried out in Royal Dockyard ropehouses, among Britain’s largest industrial establishments during the Georgian period. The process involved:[13]
- Preparation and combing of imported hemp fibres
- Spinning of yarns
- Formation of strands
- Laying-up of the completed cable
- Tarring and finishing
- Inspection by Navy Board officials
Principal Places of Production
Portsmouth Rope House
The principal source for many ships at Portsmouth was the Royal Dockyard Rope House, a structure over 1,000 feet long enabling manufacture of exceptionally long cables in a single operation. Given Victory’s long association with Portsmouth, many replacement cables were likely manufactured there.
Chatham Ropeyard
The Royal Dockyard at Chatham had a similarly important ropewalk and supplied large quantities of cordage and anchor cables. Production methods were governed by the same Admiralty regulations as at Portsmouth.
Use on Board HMS Victory
HMS Victory carried several classes of anchors: Best Bower, Small Bower, Sheet, and Stream Anchors. The heaviest cables were assigned to the principal bower anchors. When weighing anchor, a continuous messenger cable was used with nippers to attach the anchor cable, allowing it to be drawn aboard progressively as the capstan revolved. The operation required large working parties – over 100 men might be employed at the capstan bars in difficult conditions.
Rigging
The most important dimensions are known from contemporary British Admiralty regulations and reconstructions.[14]

The Ropery at the former Royal Dockyard in Chatham
The Ropery at the former Royal Dockyard in Chatham was one of the most important sites for the British Navy. Built between 1786 and 1791[15], the building is approximately 346 meters (over 1,100 feet) long – necessary to produce long ship’s ropes in a single piece.
A ship of Victory’s size required about 31 miles (~50 km) of rope for rigging, anchors, and running gear. The ropes for Victory were made in Chatham, and the rope-making workshop still supplies rope for restoration work today. The Ropery is still in operation, considered the last originally preserved naval rope-making workshop in Great Britain.
The company Master Ropemakers continues to produce ropes using traditional methods for historic ships, theatres, film productions, and other specialist applications. Some production still uses Victorian-era machinery. Visitors can tour the Rope Walk and watch the rope makers at work.
