On the sea
(There is never an ocean in all Grail legend)
There is a boat. De Troyes
Parzival
There is always one lone person on it sailing
Widershins. OED

His name is Kate or Bob or Mike or Dora and his sex is
      almost as obscure as his history.
Yet he will be met by a ship of singing women who will embalm
      him with nard and spice and all of the hallows.
As the ocean
In the far distance.
