I am sure that Clonmacnoise was raided on multiple occasions by the Vikings, and to get to Clonmacnoise, you have to sail to Limerick (very definitely on the west coast) and then all that way up the Shannon!
Clonmacnoise is smack dab in the middle of Ireland. Plus, the Vikings probably came down the river from Co. Cavan/Fermanagh.
