WAIANAE BOAT RENTAL FIELD GUIDE
Three Tanks, One Solitary Coast: Wrecks and Lava Tubes off Waianae
A full-day, three‑tank charter from Waianae that opens on the Mahi wreck and moves through deep reefs and lava-tube sites, useful for planning dives where the guide selects sites by daily conditions.
Three Tanks, One Solitary Coast: Wrecks and Lava Tubes off Waianae.
Off the rugged west shore of Oʻahu, a single charter from Waianae threads the line between wreck hunting and volcanic reef exploration: the 3 Tank West Side Dive Charter runs three dives in succession—beginning on the wreck of the Mahi, moving through deeper reef or cavern systems as conditions allow, and finishing in a shallow lava‑tube reef—under a guide who chooses the best sites for the day.
Highlights
Outing Highlights
First Drop: The Mahi LCU
The charter opens on the Mahi, one of the landing craft utility wrecks—an immediate focus for divers who want the layered interest of artificial structure and resident reef life.
Deep Reefs, Caves or Another Wreck
For the second dive the crew may run a deep reef such as the Black Rock Sea Cave, another wreck, or a lava‑tube site—the decision is made day‑of to match sea state and visibility.
A Shallow Lava‑Tube Finale
The third dive is a shallower lava‑tube reef, offering a different topography and a gentler exit to close out the three‑tank schedule.
