I arrived into Dublin by sea last year and there were no checks whatsoever.
Probably for the same reasons that for the purposes of inbound COVID rules, the Republic of Ireland treated Great Britain as just another foreign country, while the UK treated all of Ireland as domestic.
Technically only British and Irish citizens born in the CTA don't need a passport to travel between the UK and Ireland.
When I have travelled between the UK and Ireland by non-air routes, the only checks have been by local police on the GB side, and I was likely only stopped because of racial profiling.
