We Were Born For This

Our History

Maui Dive Shop’s history dates back to 1978 when Bob Chambers founded the store at the Maui Mall in Kahului. Initially, it was a small store with limited retail space. After three years of struggling, Bob closed the Maui Mall store and relocate to the Azeka Plaza Kihei, where Maui Dive Shop continued to grow as new locations became available and Maui Dive Shop established itself as a prominent retailer on Maui. Yet, new challenges were on the horizon…

The Gulf War of 1990 brought tourism to a standstill, forcing many businesses to downsize. Bob, on the other hand, chose a more revolutionary path: to expand. Opening new locations and larger stores, increasing advertising efforts, and launching a TV advertising campaign on Channel 7 the “Visitor Channel,” these moves helped Maui Dive Shop survive the tough times.

In 1994, Bob was honored as Maui’s “Small Businessman of the Year “when Maui Dive Shop had grown to operate 11 stores. Today, Maui Dive Shop operates four stores and offers a wide variety of activities that complement their charters, including luaus, helicopter tours, dinner cruises, bike tours, and horseback riding. The company aims to provide excellent customer service, quality merchandise, and first-class facilities.

Molokini is a marine reserve with spectacular water clarity and a pristine coral reef. Rated one of the best snorkeling spots in the world, this reef has a variety of beautiful reef fish and animals. More than 400 varieties of fish are found in the Hawaiian waters and more than 25% of these are endemic, they are found only in Hawaii. Between December and April, this trip affords a great opportunity to see Humpback whales in the National Marine Sanctuary.  Turtle Town offers a large coral reef system and is located near Makena State Park. The caverns and ledges in the coral and lava create the perfect habitat for sponges, corals, octopus, fish, eels, and shrimp.

Ecotourism and Outreach

Maui Dive Shop and Ali’i Nui Sailing Charters have been champions in preserving and protecting the environment since the companies were founded in 1978. Our team strives to reduce our impact on the delicate ecosystems of the island of Maui, as well as the environment as a whole. We will continue to implement these practices both internally and externally in our commercial tourism practices.

How We Make An Impact

  • Coral Reef Preservation
  • Environmental Management
  • Community Development
  • Tourist Education
  • Staff Conservation Training
  • Pre-dive Environmental Briefing

Alii Nui and Maui Dive Shop stay responsible by:

  • Recycling all plastic, paper, glass, and cans
  • Pumping all waste at the dock and not depositing waste in the ocean
  • Participating in dives exclusively to clean up certain dive locations
  • Participating in beach clean-up days
  • Not using fish food to promote animal encounters
  • Using local produce and products provided by local Maui farmers and vendors
  • Drinking purified water provided by a local Maui company
  • Picking up ‘ocean trash’ throughout our daily charters

In addition, Alii Nui has implemented the following procedures:

  • Using reusable dishes, plates, silverware, coffee mugs, champagne, and wine glasses
  • As a sailing catamaran, we use less fuel than motor-powered vessels

Maui Dive Shop has received recognition from NOAAA for assisting with the freeing of an entangled Humpback Whale.
