Particulars come from her AIS broadcast and the sourced facts ledger. A type decided from her name or her operator is a guess and is labelled as one.

Her best, by register

Two measurements, kept apart.

Window best: none
Archive best: 08:07 · Archive timing, 2021 to 2026
Best race score, window: none
Best race score, archive: none

The window receiver times a gate to about a second; the national archive carries one fix a minute, interpolated to about two. Her two bests are two different measurements and are never ranked against each other.

Records held

What she holds.

None.

Observed extremes

How fast she’s gone.

Observed top speed: 14.4 kn · 18 Apr 2022 · off Charleston, SC · national archive 2021-25

From our own position archives, with reasonableness checks: a plausible top speed over a corroborated window, a direct leg between two named places. A bound carries no second fix to confirm it and is labelled as one.

Identity history

Names and numbers.

Current name: HAFNIA AVENTURINE
Former names: NAVIG8 AVENTURINE
MMSIs on file: 538005774
Hull keyed by: IMO 9711547

A ship keeps her IMO number for life and changes her name and MMSI when she is sold or reflagged, so one hull holds every identity she has carried.

What the window has seen

Last observed.

First seen: 30 November 2021
Last seen: 1 September 2025
Passages observed: 8 (4 in, 4 out)
Port calls: Seen here about once a year
Typical port stay: 80 hours (median)
Latest direction: Outbound

Last observed: Sep 1, 2025 · 4:00 am · heading out to sea (1 September 2025, 04:00). A last observed passage is where she was seen, not where she is.

Our estimate, not a schedule: Around February 2027 — based on how often we've seen her, timing uncertain after the 2026 gap · low confidence, a rough guess.
