This is a good book, I'd also recommend the story of the first man to sail around the world alone, Joshua Slocum:

Paul's is a tiny bit more accessible because of his programming background and the familiar perspective he has in his descriptions.
Captain Slocum's voyage of 1896(?) is so different; he took an old clock, and not much else, he lashes the tiller and goes down below for hours at a time to read or sleep without worrying about crashing into other boats, he tells stories of mouldy cheese induced nightmares during rough seas or chasing natives away from robbing him, or finding remote islands with communites of slightly odd people. Much of his writing is about the people he meets - they often know in advance he's making a historic voyage, so when he arrives anywhere, there's a big fuss, he's invited to dine with local dignitaries or captains of large ships, gifted interesting foods and boat parts, there's a lot of interesting things about the world of 1896. (There's also quite a bit of tedious place names and locations and passages where nothing much happens, I'm not that interested in the geography of it).

Max repos ships. The stories are amazing. You can find various pieces written about him by Googling his name such as:
