Niuhi Dive Charters
Niuhi Dive Charters operates a schedule of two-tank dive charters and is featured on The Adventure Collective. The operation offers five distinct 2-tank trips: 2 Tank Mid Shore Dives AM; 2 Tank Off Shore Dives AM; 2 Tank Oriskany Dives AM; 2 Tank Nearshore Dives AM; and 2 Tank Nearshore Dives PM. These trip names identify the formats and general timing available to divers.
Niuhi Dive Charters focuses on repeatable, clearly defined itineraries built around two-dive outings. The inclusion of an Oriskany trip highlights access to a named wreck site. Morning and afternoon nearshore departures provide scheduling flexibility for divers who prefer different times of day. Off shore and mid shore options expand the range of dive environments users can select.
As a business featured on The Adventure Collective, Niuhi Dive Charters is presented alongside curated adventure operators, which helps divers discover the available trips. The charter's published trip names make it straightforward for divers to choose between nearshore, mid shore, off shore, and wreck-focused 2-tank experiences.
All information here reflects the trip offerings and public recognition; specifics such as exact departure times, pricing, equipment rental, required certifications, or vessel details are provided directly by the operator and should be confirmed with Niuhi Dive Charters before booking.
The term '2-tank' indicates each listed trip includes two dives per outing, allowing visits to multiple sites in one day. Divers should review the operator's official trip descriptions for site features, depth expectations, booking requirements, and safety information before reserving a spot online.

Arrive early with paperwork
Print and fill the waiver before you come and have your certification and Nitrox cards ready at check-in to keep boarding smooth.
Assemble gear at the dock
Set up your scuba unit at the tank holders so you can step on board ready to go—Niuhi has limited space for last-minute assembly.
Bring a dive computer and depth instruments
Time-and-depth instruments are required for all divers; dive computers are mandatory for profiles over 80 ft to manage decompression safety.
Plan for seasickness and sun
Take motion-sickness meds before boarding and bring sunscreen and a wide-brim hat for time on deck between dives.
Complete scuba set (BC, regulator, tanks, weights)
Required—Niuhi carries no rental scuba gear, so bring your own tanks and regulator or arrange rentals ahead.
Personal dive computer and time/depth instruments
Necessary for dive planning and mandatory for dives deeper than 80 ft.
Exposure protection (3mm-7mm wetsuit or shorty)
Warm water in summer allows lighter suits, but protection helps with long surface intervals and cooler shoulder seasons.

Surface marker buoy (SMB) and reel
SMBs improve safety during ascent and signal your position to the boat in current-prone offshore waters.
