One Hour at the Sugar Boat: MV Captayannis Up Close on the Clyde
A one-hour outing from James Watt Dock in Greenock, run by Firth of Clyde Boat Tours, that brings you close to the iconic MV Captayannis wreck and offers chances to spot dolphins and porpoises.
One Hour at the Sugar Boat: MV Captayannis Up Close on the Clyde.
The MV Captayannis—known locally as the “Sugar Boat”—lies beached on the River Clyde, a half-century-old shipwreck where coastline, wildlife and maritime legend meet. This short tour traces the story of the vessel’s violent 1974 grounding and gives riders a close view of the rusting hull and the seabirds and fish that have colonised its decks, with opportunities to scan for dolphins and porpoises on the crossing.

Outing Highlights
Up close to the Sugar Boat
The tour brings you within sight of MV Captayannis, the Greek sugar freighter that keeled over on a sandbar in January 1974. Decades of exposure and looting have left the hull and deck largely intact, now serving as habitat for seabirds and fish.
Spotting dolphins and porpoises
Alongside the wreck visit, the short cruise offers the possibility of seeing marine mammals such as dolphins and porpoises on the River Clyde.
A dramatic night in 1974
The story of the Captayannis is central to the trip: fierce winds, a ripped hull after a collision with a tanker’s anchor chains, and the captain’s decision to run the stricken ship onto a sandbar—actions that saved the crew but left the vessel to one day become the Sugar Boat.
