These Dark Waves by Himring  

Surf-tormented

Voronwe casts a look back over his shoulder. Tuor’s appearance had interrupted his line of thought. Now, at this moment before departure, he remembers.
Is he deceived or has the coastline of Nevrast changed since Turgon’s people left for Gondolin? There was more sand there surely? Has it all washed away? Has the sea even eaten into the rock?
Enough time has passed, he supposes, and the force of the waves battering the shore is strong enough. And yet he shudders inwardly, as if with a sudden vision of the lands of his childhood swallowed whole.
He looks resolutely ahead.
