Two Steam Packet employees being contacted by track and trace is the reason behind the cancellation of sailings.
It comes following the news all sailings for the next 24 hours have been called off due to 'Covid related issues'.
In a statement, Company Chief Executive Mark Woodward confirmed two members of its crew have been contacted by track and trace last night.
He says as a result the sailings schedule has to be readjusted for the next couple of days.
However, the Arrow, and the Ben-my-Chree will be back to cover daytime sailings from tomorrow.
Mr Woodward commented: ‘As ever, the safety and welfare of our passengers and crew remains our top priority and procedures and protocols are in place to reduce any spread on board our vessels. We apologise for any inconvenience caused to our passengers and appreciate their understanding in this matter.’
