“Sailings affected are from Thursday 26 October through to Thursday 2 November, when she will resume services from Portsmouth to the islands,” said a spokesperson for Condor.
“The limited number of passengers affected are being notified by contact centre staff and offered alternative sailings.
“We regret the inconvenience caused which is being compounded by poor weather forecast for this weekend.”
During the first week of service the Islander managed to berth in Guernsey for its first scheduled journey, but had to skip Jersey due to a “technical issue”. It has since managed to berth in Jersey.
A tugboat called Christine was on standby while the Islander docked in Guernsey earlier this week.

The former MV Straitsman left New Zealand in mid-April to sail across the Atlantic Ocean to its new role as part of the Condor fleet serving the Channel Islands.
Now rebranded as the Condor Islander, it previously served the Cook Strait for more than a decade after entering service in 2010.
The vessel was bought by Condor Ferries and the States of Guernsey following a deal being made earlier this year.
Guernsey’s Policy and Resources Committee loaned Condor £26million to bolster £6million in joint equity from the States and Condor to buy the ferry.
