Important note:

The schedule is submitted to the Ministry of Mercantile Marine every Friday so, in some cases, there can be some changes from week to week, let alone from month to month. It’s advisable to double check the ferry schedule couple of days prior to the departure.

Note:
The article was first published in 2010; latest schedule and price update was made as of March 2013.
Although I kept October in the high season paragraph, due to the number of ferries running on the route during this month, it’s certainly low season and trickier to plan a trip.
