In brief
MV Glen Sannox is a car and passenger ferry constructed at Ferguson Marine in Port Glasgow for the Scottish Government asset company CMAL, to lease to its ferry operator Caledonian MacBrayne. Entering service informally to the Isle of Arran on 12 January 2025, formally on 13 January 2025, she is the first of two dual-fuel CalMac ferries, capable of operating on either marine gas oil, or LNG which offers a marked reduction in sulphur dioxide, nitrous oxide and carbon dioxide emissions, the other being the MV Glen Rosa. The ship's name recalls an earlier Arran ferry.
The ship's sea trials began in February 2024, and she was moved to Inchgreen Quay in Greenock, freeing the Newark Quay at the shipyard for the launch of MV Glen Rosa.
After difficulties in completing the LNG power system, there were further delays.
Filling the LNG tank (bunkering) was completed by 18 September, and sea trials using LNG began on 20 September.
Manufacturer's sea trials were successfully completed on 23 October.
On 19 November 2024, Ferguson Marine announced that the vessel had passed its final certification checks and been issued with a passenger certificate. The ship was handed over to CMAL on 21 November.

In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 7,272 gross tons, Glen Sannox is the 39,818th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 1.2 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 877 ro-ros held here, it ranks 405th by tonnage — larger than 49% of that group. Their median tonnage is 7,395 GT, and the largest tenth begin at 34,011 GT. The flag most often flown by this group is Italy (62 ships). The yard that appears most often against it is Flensburger Schiffbau-Gesellschaft, with 16 hulls on record.
United Kingdom is the country of registry for 2,394 vessels in this directory, of which Glen Sannox is the 454th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (1,835 ships), and the median vessel measures 2,515 GT. Browse every ship flagged United Kingdom.
Narrowing to both dimensions at once, this registry holds 25 ro-ros flying the United Kingdom flag, of which 13 are larger by tonnage.
The registry attributes 61 vessels to Ferguson Marine, with a median tonnage of 2,181 GT, delivered between 1939 and 2016. See the rest of that yard’s output.
At 102.4 m overall, Glen Sannox is 22.5 m shorter than the 125.0 m median for ro-ros on record, with a beam of 17.0 m and a draft of 3.5 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9794513 this registry holds 34 other vessels, whose median build year is 2017 and which range from 2016 to 2019. That places this hull’s registration in the same part of the series; no build year is recorded for this vessel itself.
Its IMO number, 9794513, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 7×6 + 9×5 + 4×4 + 5×3 + 1×2 = 183 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
