The ferry between the Isles of Scilly and Cornwall's coast is set to sail again today after breaking down on Wednesday 28 August.
It happened at sea just off Land's End four miles south west of Gwennap Head, following technical failures with both engines.
The passenger ferry was initially scheduled to sail again yesterday (Saturday 31 August) but the company was forced to cancel.
Members of the public were asked by Isles of Scilly Travel not to contact the company because of the volume of calls it had been receiving.
An update on the website said:
The ferry, which left Penzance at 09:15 on 28 August, was forced to return to base after engine failures.
One of the two failed engines was restarted and a Sennen lifeboat escorted the ferry back to the mainland.
Isle of Scilly Travel apologised for the disruption to passengers' journeys, but said the situation was beyond their control:
Passengers are still advised to keep checking social media channels and the Isles of Scilly Travel website for further updates.
