Research notes and uncertainties

Specifications and onboard facilities are published listing claims, not a current inspection or live vessel position.
Operator product page gives 35 m and 18 twin plus four double cabins. Booking table gives 36 m and nine cabins; its prose gives 22 cabins. Operator travel-guide page additionally mentions a quad room; cabin configuration should be reconfirmed.
Earlier research, superseded by corroborating identity sources on 2026-10-18: Ocean Quest II IMO 8717398 is a plausible 1988 Australian passenger-vessel candidate, but no explicit operator-to-registered-name link was located; identity was withheld.
Registered name adds II to the marketed Ocean Quest name. AISfriends beam 15 m conflicts with marketed/detailed-hull 13 m, so AIS dimensions are not imported.
MMSI is from a published vessel directory without a recent timestamped position. It is an identifier candidate for live reception, not evidence that the boat is currently transmitting.
AMSA registered length is retained as a separate fact; the published 35 m overall length is not overwritten because the measurement bases may differ.

Not yet verified: Owner, Draft, Crew, Hull.
