When he says that ‘..the sea took him..’ like he was being stripped away from all the things he ever loved, left so alone, in merer isolation from the life he knew before.

Also the last is when it says that ‘.. Showed me suffering in a hundred ships..’ makes me think that he is at the bottom of the ocean, showing the fate, and the suffering of those in boats before him, the image in my mind is an old man, who is being swept under the waves, in cold icy dark water, not moving just paralyzed in an intense state of shock and suffering all his own.

That’s my interpretation.

Hope I’ve Helped!~

The sea sweeping him back to lonesomeness

hundred ships showing him suffering

I didn’t really get the 3rd line.
