Does this look like an "itinerary change" to you?
Just got an email from NCL that due to Ireland recently disallowing tendering from October to April, our Ireland cruise for Oct '24 has an "itinerary change".

Cobh is a sheltered inlet with berth.
That should be safe unless really bad or they do a lot of changes.
Dun Laoghaire is Irish sea, even in calm weather there are escort Ribs for tenders as the harbour has a lot of activity with small vessels some sail.
