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: 08:22 · Archive timing, 2021 to 2026
Best race score, window: none
Best race score, archive: +1.1

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: 18.5 kn · 19 Apr 2026 · off Cape Hatteras, NC · NOAA archive
Fastest leg: Jacksonville, FL to Savannah, GA · 14 h 26 m · 7.7 kn average · 21 Apr 2026 · to the hour

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: ONE WREN
Former names: none on file
MMSIs on file: 431888000
Hull keyed by: IMO 9784776

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: 22 November 2021
Last seen: 26 April 2026
Passages observed: 25 (12 in, 13 out)
Port calls: Seen here about 3 times a year · every 4 months, fairly regular
Typical call interval: 125 days (median)
Typical port stay: 32 hours (median)
Latest direction: Outbound

Last observed: Apr 26, 2026 · 9:56 am · heading out to sea (26 April 2026, 09:56). A last observed passage is where she was seen, not where she is.

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