Seasport Divers

What Seasport Divers does

Seasport Divers, doing business as Kainani Inc., is a family-owned scuba diving operator headquartered at 2827 Poipu Road in Koloa (Poipu), Kauai, Hawaii. Founded in 1987 by current owner-operator Marvin Otsuji, the company has operated continuously for over 37 years and is the only PADI 5-Star Instructor Development Center (IDC) on the island of Kauai. The business serves two primary customer groups: (1) tourists visiting Kauai seeking guided scuba experiences and certification, and (2) Hawaii residents enrolled in the Kama'aina Club membership program. Service tiers span entry-level experiences (Discover Scuba, Bubble Maker for children ages 8-9) through full professional certification (Divemaster and Open Water Scuba Instructor pathways), plus retail equipment sales and guided dive trips at over 80 documented Kauai sites including the seasonal Ni'ihau (Forbidden Island) and Lehua Crater excursions.

The underlying technology stack is built entirely on third-party SaaS rather than proprietary software. The website runs on Yootheme CMS; reservations and availability are managed through embedded FareHarbor booking flows (separate flows for activities and classes); digital waivers are processed via WhereWolf; and course content is delivered through PADI's eLearning platform. Two Coast Guard-certified purpose-built dive boats — Anela Kai (PRO48) and Anuhea (32ft Hawaiian-made power cat) — provide the physical infrastructure for guided diving, with capacity strictly limited to 10-18 divers per trip.

Revenue is generated through four primary streams: (1) one-time PADI course fees ranging from $299 (Nitrox specialty) to $2,075 (Divemaster professional track); (2) per-person guided dive trip pricing from $145 (single-tank shore dive) to $450+ (Ni'ihau excursion); (3) hardware sales through the in-store retail shop carrying Scubapro, Oceanic, and Aqualung brands; and (4) recurring subscription revenue from the Kama'aina Club membership ($125-$450 annually). The go-to-market motion is direct-to-consumer, channeled exclusively through the company's own website, phone reservations, and the physical storefront, with no third-party resellers or distributors. Marketing relies on organic Instagram (#Divekauai), Tripadvisor/Google reviews, the PADI global directory, and local tourism partnerships.
