San Juan Nepomuceno – Spanish 74-gun ship of the line and the Battle of Trafalgar
The San Juan Nepomuceno was one of the most famous ships of the line in the 18th-century Spanish Navy. Originally armed with 74 guns, this two-deck ship was built at the royal shipyard in Guarnizo, Cantabria, and was launched on 18 October 1766. It was part of a new generation of Spanish warships built according to the French-influenced design system of the naval architect Francisco Gautier. The San Juan Nepomuceno became famous for its role in the Battle of Trafalgar on 21 October 1805 under the command of Cosme Damián Churruca.
In the mid-18th century, Spain modernised its fleet to meet the growing demands of naval warfare. Traditional Spanish construction methods were supplemented by new insights from France and Great Britain. Francisco Gautier developed a ship design for the Spanish Navy that was intended to combine high structural strength with good sailing performance.
The San Juan Nepomuceno was one of a series of six large warships built at Guarnizo under the supervision of the contractor Manuel de Zubiría. Her sister ships included, amongst others, the San Francisco de Asís, San Lorenzo, San Pascual, San Agustín and Santo Domingo. The ships were characterised by a hull that was highly efficient for its time and good manoeuvrability.
As a third-rate ship of the line, the San Juan Nepomuceno was designed for combat in a closed battle line. Her main armament was mounted on two superimposed gun decks. The heavy guns of the lower battery were primarily used to engage enemy hulls and gun positions, whilst the lighter guns of the upper battery could also be used against deck superstructures and rigging. The original classification as a 74-gun ship remained in place, although the actual armament changed over the course of its service.
The three masts carried a full set of square-rigged sails with additional staysails. This combination made it possible to manoeuvre the warship’s considerable mass even in changing wind conditions. At the same time, operating the numerous sails, guns and technical equipment required a large, well-trained crew.
During her long service, the San Juan Nepomuceno took part in various operations of the Spanish Navy. These included missions in the Atlantic and the Caribbean, as well as participation in fleet operations during the European naval wars of the late 18th century. The ship was also involved in the Battle of Cape St Vincent in February 1797.
The San Juan Nepomuceno gained particular significance through its last commander, Cosme Damián Churruca y Elorza. Churruca was not only a naval officer but also a distinguished scientist and hydrographer. His work on navigation and surveying contributed significantly to the development of Spanish seafaring. In 1805, he assumed command of the San Juan Nepomuceno and prepared the ship for the impending engagement against the British fleet.
On 21 October 1805, the combined Franco-Spanish fleet under Admiral Villeneuve encountered the British fleet under Admiral Horatio Nelson off Cape Trafalgar. The San Juan Nepomuceno was part of the formation of allied warships when the British attacking columns broke through the battle line.
During the engagement, the Spanish ship was attacked by several British warships and sustained heavy damage. Despite the increasingly hopeless situation, Churruca ordered the fight to continue. According to historical accounts, when he was seriously wounded in the leg by a cannonball, he initially remained at his post and continued to issue orders.
Churruca died of his wounds, and other officers and numerous crew members also lost their lives during the battle. After the San Juan Nepomuceno had been rendered largely incapable of fighting, the remaining crew surrendered. The ship was captured by the Royal Navy and subsequently taken to Gibraltar.
The British later used the heavily damaged San Juan Nepomuceno as a stationary vessel in the harbour of Gibraltar. According to one account, the former captain’s cabin was treated with special respect out of deference to Churruca: visitors were required to remove their headgear upon entering. The ship was eventually scrapped in the early 19th century.
Today, the San Juan Nepomuceno stands as a prime example of the technical development of Spanish warship construction in the 18th century and of the dramatic events of the Battle of Trafalgar. Its history links the advances in European shipbuilding with the fate of a crew that fought in one of the most significant naval battles in history.
The San Juan Nepomuceno model kit by Artesanía Latina
With the San Juan Nepomuceno, the Spanish manufacturer Artesanía Latina offers a comprehensive wooden model ship kit on a scale of 1:90. The model recreates the characteristic appearance of the Spanish 74-gun ship of the line with its two gun decks, three fully rigged masts and numerous deck fittings.
With a total length of 960 mm and a height of 750 mm, the result is a large, highly detailed display model. The numerous gun ports, the tiered decks and the elaborate rigging provide a vivid impression of the structure of a Spanish warship during the Napoleonic Wars.
The hull is constructed using the classic keel-and-frame method. Precision laser-cut components form the basic framework of the hull. The characteristic hull shape of a large two-deck ship of the line is achieved through careful planking with wooden strips. Of particular importance here are the uniform lines in the bow section, the detailing of the stern and the positioning of the gun ports.
The wooden planking allows for customised surface finishing. Through careful sanding, filling and subsequent painting, the hull sections typical of Spanish warships of this era can be recreated. The kit uses various types of wood, suitable for both load-bearing structural parts and visible detailing.
Among the model’s most important features are the numerous guns. The gun ports, arranged in several rows, illustrate the enormous firepower of the historic ships of the line. The kit contains metal parts and matching fittings for recreating the artillery and other deck fittings.
The decks are fitted with numerous functional and decorative details. These include, amongst other things, gratings, companionways, railings and various fittings for the ship’s operation. The stern galleries and the design of the aft deck also contribute significantly to the historical appearance.
The three masts, together with the yards and the extensive rigging, form another key feature of the model kit. The San Juan Nepomuceno was a fully-rigged warship equipped with a large number of square sails, staysails and the associated lines. The model reproduces this complex rigging system with its characteristic proportions.
A special feature of the kit is the pre-sewn cotton sails. They ensure a uniform representation of the sail areas and save the model-maker the time-consuming task of making the individual sail panels. Together with the included rigging lines and fittings, a comprehensive standing and running rigging can be assembled.
The kit contains numerous other individual parts made of wood and metal, including brass fittings and cast components. The various materials allow for a detailed construction of the hull, armament, deck fittings and masts.
A wooden model stand is also included and provides a suitable base for displaying the finished warship.
Construction and Contents
The San Juan Nepomuceno by Artesanía Latina is a challenging wooden ship model for experienced model-makers. The manufacturer explicitly classifies the kit as belonging to the highest difficulty category. The size of the model, the extensive armament and the complex rigging require experience, patience and careful planning of the individual construction stages.
Construction begins with the assembly of the laser-cut keel and frame structure. The hull is then planked with wooden strips. Particular attention must be paid to the curved hull shapes, the correct alignment of the gun ports and the transition between the various deck levels.
Further work involves the guns, the deck fittings, the stern galleries and numerous small fittings. Particularly in the case of a ship of the line with several gun decks, the precise and uniform arrangement of the individual parts is crucial to the overall appearance.
One of the most labour-intensive stages of construction is the rigging. The production of the shrouds and stays, the fitting of the yards, and the routing of the running rigging all require a systematic approach. The pre-sewn sails simplify this part of the model-building process, but do not replace the careful assembly of the extensive rope work.
The model kit comprises around 1,000 components and includes laser-cut wooden elements for the hull construction, wooden strips, various hardwoods, brass parts, cast metal fittings, cotton rigging twine and pre-sewn sails. The wooden display stand supplied allows the finished ship to be displayed.
Artesanía Latina provides detailed step-by-step assembly instructions with numerous illustrations and supplementary construction drawings. The construction documents are supplied in digital form on DVD. A printed set of assembly instructions is not included in the scope of delivery.
The digital instructions and plans can also be downloaded from the manufacturer’s website. This means the construction documents can be accessed even without a DVD drive.
Paints, adhesives, varnishes and model-making tools are also required to complete the model and are not included in the kit.
The San Juan Nepomuceno is an impressive model of one of the most famous Spanish warships of the 18th century. The combination of the original’s historical significance, its classic wooden construction, extensive artillery and full square rigging makes this kit a particularly appealing project for experienced ship model-makers.
