The Chief Minister is set to be asked how many times Steam Packet vessels have been unable to dock in the last three years.
Douglas South MHK Claire Christian wants to know how often the Ben-my-Chree and Manannan have had to return to their port of departure due to being unable to dock.
She will also ask what the average cost to the Steam Packet Company is each time this happens.
The questions will be answered at this month's Tynwald sitting which is due to get underway at 10am on Tuesday.
