Red Funnel's hi-speed service will only be operating hourly until Tuesday, at 45 minutes past the hour from Southampton and 15 minutes from West Cowes, Isle of Wight.
The reduced service is as a result of a breach in the hull in one of its ferries, which now requires urgent repairs. The company's backup vessel is out of service due to its annual refit, Red Funnel said.
