The personification of the sea is used as a metaphor of the mans life. He is reaching the end of his journey as he starts to weaken as showed by the "slow surf" suggesting he is losing his ability to proceed. He is close to breaking point as we are provided with the image of the surf as it "seethed" as all of his hard efforts on the journey start to appear futile. We can assume this is due to the realisation that the journey hasn't ended as he expected for example the sea not being blue. He starts to loose all his positivity and as this is what drove him to keep going he feels he now has "no life". His life was the journey and it is now over as he was holding on to reach the coast in the expectation of a better life, however he assumes if the sea is not blue what other disappointment lies
