Three-Tank Twilight: Double-Dip the Sea Tiger and a Night Reef Immersion off Honolulu.
Departing late afternoon from Honolulu aboard the private boat Ocean Therapy, this three-tank outing stitches together daylight wreck exploration and a wholly different nocturnal reef world—two visits to the famed Sea Tiger wreck and a final night dive where reef life rewrites its rules.

Outing Highlights
Double-dip the Sea Tiger
Two successive dives on the Sea Tiger let divers survey the wreck from different angles and extend underwater time at one of Oahu’s most compelling artificial reefs.
Afternoon Into Night
The charter departs in the afternoon and moves into evening, giving participants the rare chance to experience the same general area in broad daylight and then again under the altered rhythms of night.
Turtles, Eels and Night Creatures
Expect encounters with endemic marine life on the wreck and reef dives—everything from sea turtles and eels during the day to nocturnal reef activity and bioluminescent phenomena after dark.
What the day feels like
What This Triple-Dive Feels Like
The boat leaves mid‑afternoon for a concentrated dive program: two deliberate passes over the Sea Tiger shipwreck—each offering a fresh vantage—and a concluding night reef dive that transforms familiar reef contours into a theater of nocturnal activity. The schedule is compact and built to maximize bottom time while moving from daylight into after-dark conditions.
