I'm not buying it that there is a self-curing island boar that hasn't been exploited to the point of extinction. We work to destroy out ecosystem, no way free bacon gets a pass. No way in hell.The island can't cure meats. It's not some fantasy island. It's just that this type of pig automatically cooks and turns into bacon when it dies. You know, island boars. And the captain is busy sailing the boat. He's not cooking anything. Dude can barely cook toast. He attended culinary school when he was young and failed out. It was sad. They hadn't even really gotten to the tough classes yet. Guy was having trouble with the basics of cooking. After that, he decided to go into the Navy. Sailing was in his blood but he had always wanted to pursue his dream of being a Michelin starred chef in the restaurant he owned. But alas, that dream had been crushed. And he would become a ship's captain like his father and his father before him.
Also, you can get a can of Spam. Just not microwaved.
And if this guy can't "cook" toast, no way is he a boat captain, and certainly not ex-Navy. Sounds more like Marine material to me.
My guess is the real captain is locked in the brig, mutinied by the failed-chef-turned-washed-up-first-mate with a dictitorial streak who couldn't measure up to the standards of his fore-fathers. If you can find a way to free the Captain and help regain command of the ship, I'm quite willing to bet you'll be served the finest prepared meals the seven-seas has to offer, in any combination you desire.
