Dredging works carried out in Douglas harbour
BBCDredging work has been carried out in Douglas Harbour in order to prevent more disruption to marine services.
The Manxman's afternoon arrival on 1 March was delayed by 105 minutes when the ferry got stuck on a mud bank in the harbour.
The Isle of Man Steam Packet Company has been running a modified schedule until the dredging work can be completed.
A spokesperson for the Department of Infrastructure (DoI) said the work, which began on Sunday, was expected to last four days.
A specialist dredging vessel - Norma II from Liverpool - was brought in to do the work.
The DoI spokesperson said the priority had been to dredge the mound in the "main turning basin".
Any spare time would then be used to perform other maintenance duties.
Treasury Minister Alex Allinson, questioned in the House of Keys, apologised to passengers for any inconvenience, but said the DOI had responded quickly.
Infrastructure Minister Michelle Haywood explained Douglas Harbour was "dynamic" and the movement of vessels could cause underwater deposits to build up.
MHKs Chris Thomas and Julie Edge suggested the build-up had been known about by the DoI for a year, and questioned why dredging work had not been undertaken sooner.
But Allinson said the build-up was "not a known problem - otherwise the Manxman would not have ended up stranded on the seabed".
He said it was "one of the issues" of having large vessels in a small harbour at times of "extremely low" tides.
