I want to give a special thank you to two sources that inspired this revision. I have borrowed heavily from "Of Ships and the Sea" from Wizards Unearthed Arcana and "5E Seafairing Rules" form RocksInMyDryer on Reddit.

Overview | Nautical adventures and campaigns are one way that Dungeon Masters can excite and inspire their players. The promise of exploration and adventure on the high seas offers players new ways to experience their characters and the fantasy setting around them. After all, what could be more stimulating than traveling in a world where the phrase "Here there be Dragons" hastily scribbled on the edge of an old sea-dog's map signals a very real danger. A seafaring campaign can embrace anything from exploring the dark depths of an underground lake or rafting down a jungle river to magical journeys into the lightless deeps of the ocean. Your players may want a ship to use as a “home base”. When you can set sail and go almost anywhere, the opportunities for adventure are nearly unlimited. You can mix it up with Viking berserkers, samurai and ninja, and savage headhunters, looting along the way. The world awaits with different types of adventures: city adventures in the ports, sea-based adventures, dungeon adventures following up on clues in treasure maps, work as a courier or spy for some kingdom or religion, etc. A ship-based campaign makes it easy for the DM to change things up, which makes things interesting and enjoyable for players. Or they may want to be pirates . There’s something about a swashbuckling pirate with a parrot on his shoulder that makes women swoon and men more than a little jealous. Their very names conjure images of adventure; ships flying the skull-and-crossbones banner; sailing into forgotten island coves loaded with exotic items, both magical and mundane; and treasure maps leading to piles of cursed gold and gems. Their brief lives are a complex mix of ruthless discipline and the belief in every man’s right to live as he wishes to live and die free. This supplement is not about conducting massive sea battles, moving small model ships around on a hex battle map exploring tactics and the intricacies of wind and sail. Rather this is about what the PCs can do with ships. Ship-to-ship battles do take up the majority of the pages here, but the battles are from the point of view of the player characters on board their ship. Care has been taken to assure each payer has something to contribute each round of ship-to-ship combat. Each player controls one of their ship’s officers . That officer can be his or her PC or it may be an NPC and he has several actions available to him that are specific to that officer. By Ronny Hart—November
