All routes will be able to be viewed on the website on Thursday January 19. Bookings will then open on Friday January 20, except for the three routes operating from Mallaig, which will open for bookings by January 31.
Customers can book tickets through the CalMac website at 7am on Friday, and by phoning the contact centre or at port offices from 9am.
'Mallaig routes require additional time due to the number of tidal amendments required and the complexity of operating three services from the one berth in Mallaig,' a CalMac spokesperson explained.
'We are working to finalise timetables for the last week of the summer timetable (the period between 16 and 22 October inclusive).
'These will be made available as soon as possible, once community consultation and work to finalise vessel deployment during the start of the annual overhaul period has been completed.'
Robbie Drummond, chief executive of CalMac, said: 'I am very pleased to be able to announce the release of the summer timetable for 2023, but apologise for the late publication. We understand the impact this has on island communities and local businesses.
'The publication of the timetables will be welcome news to the communities we serve and to visitors, who can now plan their summer holidays.
'I am grateful to all our customers who have been waiting for longer than usual for this news and thank them for their continued support and patience.'
A local MSP welcomed the delayed publication of the summer ferry timetable, but urged CalMac to put in guarantees that future programmes will be issued sooner.
Highlands and Islands MSP Donald Cameron urged CalMac to guarantee a more prompt publication in future years.
Scottish Conservative Highlands and Islands MSP Donald Cameron said: 'While it’s welcome this timetable has eventually been published, it happened far too late.
'We can’t see a repeat of this in future seasons, so CalMac should commit to getting these finalised and circulated sooner.
'Delays in issuing timetables causes huge headaches for the tourism and hospitality industry on the islands, not to mention individuals who want to make their own arrangements.
'The excuses given were met with scepticism in these communities and rightly so. People and businesses deserve more clarity in future years.'
