Abstract Erdmann and co-authors (2018) present interesting observations of coastal boulder deposits along Ireland's western seaboard, Unfortunately, some of their interpretations are undermined by inaccurate information; and two of their main conclusions—that boulders greater >50 t were not moved during the recent strong storms, and that boulders 20–30 t were not moved significantly against gravity—are incorrect. Field records from before and after the storm events clearly show that boulders weighing 10 s to 100 s of tonnes were moved inland and uphill.
