Why dive here
With 362+ marine species recorded in the area - including barracuda, blacktip reef sharks, dolphins, dwarf minke whales and humpback whales - NATHALY offers some of Long Island's richest wreck diving. Water ranges 26-30°C, warmest August, September, October.
The Nathaly isn't about depth, it's about intimacy. Sitting in a barely-there two metres of water, this motor vessel wreck is practically begging for a snorkel or a free-dive. We love how the shallow depth brings the whole scene into sharp focus, making every detail of the hull and superstructure pop without needing a dive computer. It's a fantastic spot for photographers too, the ambient light just floods the wreck, painting it in all sorts of blues and greens, especially on a sunny afternoon. You can easily spend an hour finning around, peeking into the wheelhouse, and watching the resident parrotfish graze on the algae growing thick on the metal. Our favourite part has to be the way the light plays through the gaps in the collapsed deck, illuminating swarms of tiny silversides darting in and out of the shadows. For a chill afternoon in the water, the Nathaly is our top pick on Long Island.
