Be sure to check out Reeds and / or the appropriate pilots for more detailed information and alternates, this is just an overview of likely candidates, but I have been to all of them. I am generally only concerning myself with anchorages as harbours and marinas are well covered in Reeds.
To see my recent visits to each anchorage check out the "Labels" towards the bottom of the right hand panel.
If the tides work to get round Lands End from Newlyn to be at Cape Cornwall at a sensible time and with an east bound tide (as there should be) then St Ives is an excellent setting off point for SE Ireland or South Wales BUT only in settled conditions, it is very exposed to onshore winds and Atlantic swell and waves can refract round the headland to make the anchorage untenable, remember Newquay further up the coast is a surfing mecca for that very reason.

If going up the west coast of Wales then Milford is an obvious stop off point and it works well to or from Ireland depending on the wind and it has an anchorage to suit most winds. The most convenient are Dale Shelf with winds with west in them, Sandy Haven Bay for north westerlies to easterlies and West Angle Bay for easterlies and Angle Bay for southerlies. If the wind changes you will probably have to move as the water can get quite uncomfortable, although not dangerous very quickly. There are a number of good anchorages above Cleddau bridge but its quite a long way.

The East Coast of Ireland
St Margaret's Bay
Sorrento Bay, DublinJust south of Dublin Bay, it is a good anchorage when the wind has west in it and in 2021 I spent a good night there in a strong northerly. You need to be quite close in for shelter and out of the deeper water.
|Sorrento Bay, 2020. the following year I went a bit further west|
away from the bathing area. Jet Skies and Speed boats were
a problem for a time but didn't stay long.

The SkerriesGood shelter from the southerly and offshore winds, lots of moorings but (in April at least) plenty of room between. Quite shallow further in.
