I-MAY - St. Thomas & St. John
Dropping onto the I-MAY, you’ll find a motor vessel that capsized and sank back in 1976. It’s sitting upright at about 45 metres, a proper deep dive that suits advanced divers comfortable with overhead environments. The wreck itself is reasonably intact, offering some interesting penetration points for those with the right training and gear. Over the decades, the I-MAY has become a vibrant artificial reef, completely encrusted with sponges and hard corals. We often spot schooling jacks circling the bow, and there are usually a few resident barracuda lurking in the shadows, along with plenty of smaller reef fish darting in and out of the structure.
