The ocean usually goes ashore once every six months, and it may be longer. Injuries at sea are usually not treated effectively.
Serious injuries can only be maintained by emergency medicine, and only when the supply ship comes up. Besides, if you are fishing for others, I advise you to resign. Really bitter, dirty, fishy and tired. I can't go out to sea for a few days because of the bad weather, and I don't even have food. If you rent a boat to go fishing, that's fine, but you'd better find an experienced master to take you there. It's hard to make money now. Fishing was very profitable a while ago, and many people went there, so the competition was fierce.
