Everyone plays their own island. Harbour Party lets you send each other goods.

Run it on the same local network and you find each other automatically - no addresses, no lobbies, no accounts. Each captain lists what they need, everyone sees those lists, and you ship goods across with one click.

How it works, plainly:

  • Opens a TCP socket on port 27960 and broadcasts UDP on 27961, both on your local network only
  • Nothing leaves your LAN: no servers, no telemetry, no accounts
  • Peers exchange only product ids and amounts
  • All captains must run the same game version and the same version of this mod

Requires the Trade dock research. Goods held in a shipyard cannot be sent - the game provides no way to take them back out again.
