Fastcraft season had been delayed back in March
Manannan is resuming its regular journeys to and from Liverpool today (1 July).
The fast craft will carry out four voyages, between the Isle of Man and Merseyside, during the day.
The first is due to set off from Douglas at 7.30am.
The start of the season was delayed back in March due to border closures in place at the time.
