Terms of 25-year plan would be reviewed every five years
The Infrastructure Minister says it's important that the new Sea Services Agreement can be adapted to the changing world.
Ray Harmer will ask Tynwald to approve the 25-year agreement at this month's sitting.
The document, which outlines plans for new vessels, improved ports facilities and a fares freeze, will run until 2045 if it receives the backing of the Manx parliament.
The terms will be reviewed every five years, which Mr Harmer says is vital.
