Source-derived summary

MV Jupiter was a passenger and vehicle ferry in the fleet of Caledonian MacBrayne in the Firth of Clyde, Scotland. She was the oldest of three "streakers" and the third River Clyde ship to bear the name 'Jupiter'. Her open car deck was accessible by stern and side ramps ro-ro. She entered service in 1974, and operated the Gourock to Dunoon crossing for much of her career. In 2006, she became the oldest vessel in the CalMac fleet and continued in service with them until 2010. Jupiter was sold for breaking in 2011.

History and layout

MV Jupiter was the first of a new generation of car ferries built in the 1970s to serve the routes on the Firth of Clyde. These ships came to be nicknamed the "Streakers" because of their greater speed (compared to what had served the area's routes previously) and superb manoeuvrability (due to her novel propulsion units, which greatly reduced loading and unloading times at each end of her route).

Jupiter incorporated a large open car deck towards the stern, with enclosed passenger accommodation and services towards the bow across three decks. Her design was of the roll-on/roll-off type (and technically drive-through, even though not through conventionally from bow to stern), with cars driving on via either the stern ramp or via one of the amidships ramps on the starboard side and the (rarely used) port side.

Editorial analysis

Why this record matters

The phrase “1974 Scottish ferry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 11, 2026. The linked authority identifier is Q11705682. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1974, 2006, 2010 and 2011.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
