As the waves climbed to the gunwales, the sharks circled. The sun was high in the sky, and Arthur squinted into the light, watching gulls dive. The last of the seagull he had managed to kill was gone days ago. This was day 19. He had been alone since the tenth day when Johnathan went mad and took his last swim. He was sunburned and starving, but he knew he could make it. Keep floating and eventually you will pass by land. Stay alert and someone is bound to find you.
He never should have accepted the offer. This is the thought that plagued him. He was raised to think in numbers and percentages. The call to sea was a siren song all along.
When they found the boat, it was empty. This does not mean that Arthur died. It means the boat was empty. To his family, Arthur was king of an island somewhere. He was eating coconuts and laughing. He was building civilizations from driftwood and palm fronds. His sons would become sailors eventually and traverse the world, wondering. They would look at the old, weathered men they saw in sea ports. They would hope for some flash of recognition.
They never guessed that Arthur saw his salvation as a new start. Freedom. He was tied to no one and nothing. He saw his sons occasionally from afar, but never spoke to them.
There are many things that happen on the sea. There are mysteries that will never be solved. There are ghosts that slip the valleys between waves. There are lives that blossom in salt water. There are pitfalls and disasters.
You look at the horizon and you see an invitation, but that is reckless innocence. The sea takes what the sea wants. The boats bob on the waves, but we know nothing of the worlds underneath. But go ahead and join them. You might as well go to sea. The ocean is calling you. And you might survive, or you might be lucky and be spared the torture of starvation and madness. The sea gives you what you need, whether you want it to or not.
