Private Sunset Dolphin Watch & Snorkel Cruise with Dinner and Cocktails

3.5 hoursPrivate catamaranUp to 49 guests
Catamaran at sea with guests dining on deck as sun sets
Charter the Kai ‘Oli’Oli for a private sunset cruise with buffet and beverages included.

This private charter centers on a large, comfortable catamaran and a Hawaiian buffet—designed for celebrations or large private groups who want a single‑vessel experience. Over 3.5 hours, guests have exclusive use of the Kai ‘Oli’Oli, and the itinerary is tailor‑made: mornings and afternoons can include snorkeling at select sites, while evening departures focus on a romantic sunset and dolphin watching. The vessel’s maximum capacity is listed at 49 guests, giving groups the flexibility to host extended families, corporate outings, or private events without splitting the party.

What distinguishes this option is the full‑service approach: a Hawaiian‑style meal menu and up to four alcoholic drinks per person are included in the standard offering, with upgrades available for gourmet menus and professional photography. Practical notes: roundtrip transport options are offered for Waikiki or Ko Olina properties (additional fee), a 50% deposit is due at booking, and a small automatic crew gratuity applies.

Bareboat Cruising Lessons (ASA 104)

3 days, 2 nightsInstructional courseCertification
Sloop‑rigged keelboat under sail, small crew on deck
ASA 104 offers a three‑day, two‑night progression to bareboat cruising competency.

The ASA 104 course is a focused, multi‑day progression for sailors who already hold basic keelboat and coastal cruising certifications. Structured as three days with two nights aboard, the program blends classroom and hands‑on learning to prepare participants to skipper or crew a sloop‑rigged, auxiliary‑powered keelboat in coastal waters. Core competencies include piloting, dead reckoning, docking, system troubleshooting, navigation planning and overnight anchoring; students spend two nights aboard to gain practical experience in watch routines, systems management and day‑to‑day boat handling.

Pricing is published per student and decreases with additional participants; the course includes registration, certification fees, and a logbook, plus a one‑year membership to ASA. Because this is a skills course rather than a sightseeing charter, it’s ideal for experienced sailors seeking qualification and confidence to take a bareboat charter independently.

Dolphin Warrior Private Charters

2–3 hoursZodiac speedboatSmall private groups
High speed Zodiac near ocean swells with passengers looking for dolphins
The Dolphin Warrior Zodiac is built for speed and close wildlife viewing.

Dolphin Warrior private charters are tailored for guests who want an active, wildlife‑forward outing. Operating as a high‑speed Zodiac experience, the offering includes a two‑hour dolphin watch option or a three‑hour dolphin swim that layers a reef snorkel with opportunities to spot turtles and colorful reef fish. The Zodiac’s nimble profile allows quick repositioning across prime viewing areas; operators note speeds up to 25 mph, creating an ocean safari feeling rather than a slow cruise.

Because groups rent the whole boat, the format suits families or small parties that want both adrenaline and wildlife viewing without sharing space with strangers. Snorkel gear is included for the three‑hour option, and the shorter dolphin watch focuses on observation and photography. For travelers whose priority is close encounters with marine life on a compact, high‑energy platform, this is the most hands‑on pick on the list.

The inclusion set—snorkel gear, snacks, sandwiches, fruit platters and a BYOB cooler—positions this as an elevated, flexible day on the water. Staff credentials are noted as certified lifeguards or registered nurses, which emphasizes safety alongside comfort.
