"Santisima Trinidad" (Spanish Nuestra Senora de la Santisima Trinidad - "Holy Trinity") is a Spanish three-deck battleship of the 1st class, built according to the design of the Irishman Matthew Mullana in Havana and launched in 1769. The hull and deck are entirely made of Cuban mahogany, while the masts and yards are made of Mexican pine. The thickness of the outer skin of the sides reached 60 cm. Having been equipped with 140 guns after retrofitting (of which thirty 32-pounders on the lower deck), the 63-meter ship with a displacement of 4902 tons was the largest sailing warship of its time.

 

During the American War of Independence, Santisima Trinidad was sent to intimidate the British in the English Channel. For its low maneuverability, he was nicknamed "Heavyweight" (Spanish El Ponderoso).

 

In 1795, she was converted into the world's first four-deck ship with an increase in the number of guns to 140. Despite these measures, two years later he was almost captured in the battle of St. Vincent. During the Battle of Trafalgar, a gigantic, hulking ship with a crew of 1,200, which was fought simultaneously by 7 English ships of the line, remained afloat, despite significant damage. After the battle, they tried to tow it to England for repairs, but a violent storm began and the "Holy Trinity" sank.
