Sea Tiger Wreck: What to Expect
If Honolulu scuba diving is on your Oahu agenda, the Sea Tiger wreck delivers a photogenic mix of structure, depth, and marine life. We depart Waikiki’s Kewalo Basin Boat Harbor for a concise wreck briefing, then idle over the mooring ball and splash. Giant-stride entries lead to a slow, comfortable descent to about 100 feet, where the midship corridor of the Sea Tiger comes into view. This is a certified-diver tour with Rainbow Scuba Hawaii, so the pace is relaxed and safety-forward: confirm gas, equalize early, and settle into neutral buoyancy as the wreck’s railings, winches, and companionways sharpen below. Schools of tropical fish begin to stack in the blue; a glittering wave of blue-line snapper sweeps the deck, and a Hawaiian green sea turtle glides through the scene. Later, a hop to Horseshoe Reef adds coral textures, triggerfish traffic, and another turtle greeting before a smooth ascent and return to harbor—an underwater adventure built for your Hawaii dive vlog.

Mid-Dive Highlights
From Briefing to Midship
The dive sequence mirrors our timestamps for easy planning: WELCOME & WRECK BRIEFING, CRUISE TO SEA TIGER, and INSTRUCTOR SECURES MOORING set the day’s rhythm before GIANT STRIDE ENTRIES start the fun. On the line, we make a DEEP DESCENT TO 100 FT, arriving at MIDSHIP EXPLORATION — SEA TIGER, where the superstructure frames every shot. Maintain good spacing, keep fins high to avoid silt, and carry a small light for peeking into openings without penetrating—this tour emphasizes a no-deco profile and excellent buoyancy control. The wreck offers clear reference points that help newer certified divers stay oriented while still feeling the thrill of depth and scale.
Marine Life Behavior
Blue-line snapper often gather where light and current converge, rippling across the deck at 01:52. A HAWAIIAN GREEN SEA TURTLE may cruise by with unhurried wingbeats, and at HORSESHOE REEF — TURTLE GREETING another turtle circles coral heads while triggerfish hover above. Watch for trumpetfish shadow-hunting alongside parrotfish, butterflyfish pecking at encrusting growth, and the occasional day octopus tucked under ledges.
Planning Your Rainbow Scuba Hawaii Dive
Conditions, Gear & Comfort
Expect visibility of 60–100 ft and bottom temps in the mid-70s to low-80s °F. A 3–5 mm wetsuit, low-volume mask, and mid-size fins work well for Honolulu marine life viewing. Nitrox is a bonus if you’re certified and want extra buffer at 100 ft. A compact primary light reveals detail, and a DSMB is smart for blue-water ascents. Plan a conservative SAC rate, monitor NDLs, and keep breathing smooth—good trim above the deck protects the site and stretches your gas.
Tour Flow & Safety
Rainbow Scuba Hawaii keeps things streamlined for visitors staying in Honolulu or Waikiki: meet at Kewalo Basin, review signals and route, then follow your guide on a simple loop across midship and the superstructure before transitioning to Horseshoe Reef when conditions allow. Expect steady coaching on spacing, slow equalization on the descent line, and a deliberate ascent with a 3-minute safety stop around 15 ft. Back topside, DIVER REACTION & TAKEAWAYS capture fresh impressions before we’re BACK AT KEWALO BASIN HARBOR—a tidy, confidence-building wreck-and-reef tour that fits neatly into your Oahu travel plans.
