Highlights

Outing Highlights

THE FOCUS

Freediving‑Only, Coach‑Led Sessions

The charter runs exclusively for certified freedivers and emphasizes line work and coached depth training under a professional FII instructor and coach, with trained safety divers and an experienced captain supporting every session.

THE SITES

World‑Class Kona Sites — Wrecks, Drop‑Offs, and Lava Formations

Operators select among Kona’s top freediving locations each day, including deep shipwreck profiles (around 30m/100ft) and open‑water sites (up to 60m/200ft), reef structures and lava formations, plus access to manta cleaning stations and reef shark nurseries where conditions permit.

THE BLUEWATER

Bluewater Safari for Pelagics

After morning depth or reef sessions, the trip spends several hours offshore searching for pelagic species — dolphins, whales and sharks may be observed depending on activity and conditions, though encounters are not guaranteed.

What the day feels like

What the Day Feels Like

You’ll board at Honokōhau Harbor and settle into a small‑group, coach‑focused freediving rhythm: a concentrated two‑hour morning of line depth training or deep reef dives guided by a coach and safety team, then a multi‑hour bluewater search for pelagics and a scenic cruise back to shore.

Suitability

Who it's for

Who this trip is for — and who should look elsewhere.

1
Certified FreediversIdeal — the charter is designed exclusively for certified freedivers and offers coached line time and deep water options tailored to experienced breath‑hold divers.
2
Training‑Focused DiversWell suited — professional coaching and safety support make this a good choice for divers working on depth training or refining technique under supervision.
3
Non‑certified Guests or Families with Non‑diving MembersNot suitable — the charter does not provide introductory instruction and non‑divers or snorkel‑only participants are not accommodated.
4
Wildlife and Bluewater EnthusiastsA good match for those hoping to encounter pelagics — the itinerary spends time offshore searching for dolphins, whales and sharks, but sightings depend on species activity and cannot be guaranteed.
