Why dive here
With 476+ marine species recorded in the area - including barracuda, blacktip reef sharks, dolphins, eagle rays and humpback whales - Cartanser Sr. Wreck offers some of St. Thomas & St. John's richest wreck diving. Water ranges 27-30°C, warmest August, September, October.
The Cartanser Sr. Wreck sits right in Charlotte Amalie harbour, which means it’s an easy boat ride out. We love this site for its accessibility and how much the wreck has given back to the local ecosystem. Dropping down to about 18 metres, you’ll quickly make out the freighter, broken into two main sections. What makes it a standout for us is the way the ship has transformed. The hold is open, letting you swim through and observe schools of Brown Chromis darting in and out of the shadows. Look for the resident Broom-tail Filefish, often seen camouflaged against the rust-coloured metal, or the Yellowhead Wrasse diligently picking through the crevices. We’ve spotted Spotted Trunkfish here more than once, just hanging out near the broken superstructure. It's a fantastic spot for newer divers to get a feel for wreck penetration without any serious overhead environments. The light penetration is excellent, illuminating the entire wreck and the fish life around it.
