San Jacinto Wreck

A warship's final voyage

The San Jacinto was built at the New York Navy Yard and launched in 1850, pioneering steam propulsion in the American naval fleet. She gained international notoriety in 1861 when her captain intercepted the British mail steamer Trent and removed two Confederate diplomats, nearly sparking war between the Union and Britain.

After distinguished service throughout the Civil War, the San Jacinto met her end chasing Confederate blockade runners through Bahamian waters. Navigating the treacherous reef-strewn approaches to the Abacos in January 1865, she struck hard ground and could not be freed. Her crew was rescued, but the ship was lost.

Exploring the wreckage

More than a century and a half of coral growth has transformed the San Jacinto into a living reef. The wreck lies in pieces across a wide debris field, with her steam boilers standing prominently above the coral rubble. The massive iron propeller remains intact, encrusted with marine growth but clearly recognisable.

Swimming through the wreckage reveals nooks and crannies that shelter lobster, crabs, and countless small reef fish. The boilers have become homes for large green moray eels, some over six feet long, that peer out at passing divers.

Marine life and diving conditions

The San Jacinto's coral-covered remains support a diverse reef community. Schools of snapper and grunt weave through the structure, while angelfish, parrotfish, and butterflyfish add colour to the scene. Larger visitors include nurse sharks resting in the sand and the occasional Caribbean reef shark.

The wreck's relatively shallow depth allows for extended bottom times, and the site is typically calm with good visibility. The scattered nature of the wreckage means divers can explore different areas on successive dives.

Getting there

The San Jacinto wreck is accessed by dive boat from Green Turtle Cay, typically through Brendal's Dive Center. The site lies within a short boat ride of New Plymouth harbour. The wreck can also be visited on excursions from Treasure Cay or Marsh Harbour with advance arrangements.

Frequently asked questions

How much of the San Jacinto is still intact?

The wooden hull has largely disintegrated, but metal components including the steam boilers and propeller remain recognisable. The wreckage is scattered across a wide debris field now covered in coral growth.

Is the San Jacinto suitable for beginner divers?

Yes. The shallow depth of twenty-five to sixty feet and typically calm conditions make this an accessible wreck for certified open water divers. No penetration is required or possible given the scattered nature of the remains.

What was the Trent Affair?

In November 1861, the San Jacinto stopped the British mail steamer Trent and removed two Confederate diplomats. Britain threatened war over the violation of neutral rights, and the crisis was only defused when the Union released the prisoners.
