No, his corpse+ship is in the middle of the lake to my right (out of the picture).

You can get closer to that area if you go north to the Singing Shards. It's a fallen piece of Dalamud like the entrances to Coil, but the first Coil dungeon is actually far to the southwest, between Vylbrand and Carteneau.
So a not-yet-seen entrance to Coil, then?
