Red Funnel customers have been hit by news of further cancellations to sailings today (Friday).
The company has suffered technical issues throughout the week, leading to a number of sailings not going ahead.
The cross-Solent operator earlier pulled a string of morning crossings out of service.
Now it has announced the 1pm car ferry from Southampton and 2.30pm from East Cowes have both been cancelled.
The issues have been a result of a failing generator on the Red Falcon.
Next Tuesday (July 30) will also see a revised timetable in place for Red Osprey.
