From the publisher's website:

In The Red Dragon Inn 4, you and your friends are a party of heroic, fantasy adventurers. You've raided the dungeon, killed the monsters, and taken their treasure. Now you're back in our homeland, and what better way to celebrate your most recent victory than to spend an evening at the Red Dragon Inn. You and your adventuring companions will spend the night drinking, gambling, and roughhousing. The last person who is both sober enough to remain conscious and shrewd enough to hold onto his Gold Coins wins the game. Now you've taken to the high seas aboard The Crimson Drake, a sturdy sailing vessel that the heroes you know and love use when their adventures take them to sea. Join the crew in the Captain Whitehawk's cabin for a pint and try to keep your sea legs! Captain Whitehawk: Captain Whitehawk is the stalwart master of the Crimson Drake. She's a natural leader with years of experience and a wit as sharp as her saber. First Mate Remy: An elf from faraway lands, Remy is an honor-bound swashbuckler who keeps the crew in line; he’ll be the first to step in and break up a fight. Bryn the Boatswain: Bryn is tough as nails and knows how to keep a ship afloat. Tara the Navigator: Tara was born blind, but with the gift of second sight. With her knack for seeing the future, she is an invaluable, if unlikely, navigator for the Crimson Drake. The Red Dragon Inn 4 includes a Sea Event Deck that provides a new way to play RDI. Instead of the relative safety of the inn, players are now partying in the Captain's cabin aboard the Crimson Drake – and because you're out on an adventure, the party runs the risk of being interrupted by random encounters. In game terms, at the start of the game you shuffle the Sea Event Deck and place it in the middle of the table with two Progress Counters on it. Not only will you need to protect yourself from the other players, as well as the Drink Deck, but you may find yourself forced to defend against a Sea Event.
