Still working on this. Just heard it today.
They're sailing the river Styx. Their captain is Charon. But they do find themselves in Heaven at the end. "The seventh sea-sick day" -- 7 being the number of the infinite. As with most Procol Harum songs that I've heard, Christian imagery and numerology play their part, here. They fired the gun to announce their arrival, and burned the mast because they intended never to return to their port of departure. "A salty dog, this seaman's log: your witness, my own hand" is the end of the letter. In his blindness and old age, Paul had Timothy write his last epistles. Paul came in at the end to say, "I write this in my own hand," to prove to the recipients that the letter was authentic, and that Paul was still alive. It should be written like this:

Now many moons and many Junes have passed since we made land. A salty dog, this seaman's log.

Your Witness

(my own hand)

He felt his name was unimportant, just that he had witnessed this all, and wrote it to us as a promise.
