Let more people control the same boat/boats.

Party Boat must be installed both on Server and Client to work A blur to the GUI may be caused by mods such as FancyMenu, it's not a bug of PartyBoat

To access the Party Boat features in a server, type /partyboat or press P if the keybind isn't already being used. This will open a GUI where you can create a session or accept invites from other players.

Party Boat offers full customizability: you can choose which boats are active and controlled by the party, assign certain controls to certain players and many more. A boat in order to be controlled by the party must have a player of the party sitting in it.
