What should I check before booking a ferry to an offshore island in rough weather?
Check the sailing, not just the forecast. Island operators post sailing status on the morning of travel and cancel on wind and sea state, so read the operator's own updates before leaving the mainland, then check Met Eireann's marine forecast for the inshore waters and any small craft warning. Allow for the return crossing to be the one that fails: pack an overnight bag, keep the mainland bed flexible where you can, and never place a non-refundable flight or a fixed booking on the evening after an island trip in winter. If the operator offers a change to an earlier sailing, take it.
