An advanced two-tank boat charter out of Hawaii Kai that pairs a deep wreck exploration with a current-driven drift along Maunalua Bay’s reef slopes. Open Water certification required; Nitrox available onboard.
More ways to explore the area's outdoor wonders
You step onto the aluminum ladder as the boat rocks gently in Maunalua Bay, the island’s eastern fringe unfolding in the distance: basalt ridges cut by ancient lava flows, a rim of palm-lined coastline, and water the color of melted aquamarine. Gear clicks into place; the captain runs through the plan—a deep wreck first, then a current-fed drift where the reef drops away into blue.

History
Many wrecks off Oahu have military or commercial origins; over time they’ve become artificial reefs that support diverse marine life and local dive culture.
Conservation
Maunalua Bay and surrounding reefs are subject to marine-protection guidelines—avoid touching coral, use mooring buoys when available, and follow crew briefings to minimize impact.
Reserve your spot on the Two Tank Wreck and Drift Dive in Oahu today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Arrive Early and Fueled
Arrive by 7:30 AM, eat a light meal and hydrate—boat check-in is strict and the morning sun can be intense.
Bring Your Certification Card
Operators require proof of Open Water certification or higher and may ask to see recent dive logs for deep or drift sites.
Plan for Currents
Be comfortable with drift diving techniques—practice neutral buoyancy and buddy communication to handle variable currents.
Consider Nitrox
If you’re qualified, using Nitrox can extend no-decompression time on deep wreck dives—ask the shop about fills and fees.
Personal Dive Computer
Tracks depth and no-decompression limits precisely during multilevel wreck and drift dives.
Certification Card & Logbook
Proof of training and recent experience required at check-in and for certain sites.
3–5mm Wetsuit or Rashguard
Thermal protection for long bottom time and protection from reef contact; thickness depends on tolerance.
