This is a modpack that I made to host a server with my friends. I tried to include mods that fit the theme of ocean exploration and colony sim. I am uploading it to CurseForge to make it easier to update on both ends.
Feel free to download and play with your friends! It runs fairly stable on my server. For a more smooth experience I would spend a day before pre-loading chunks with Chunky, and then enabling Distant Horizons server-side so all players get the LODs uploaded to their client.
A key detail for this modpack is that vanilla Minecraft boats will break when entering ocean biomes. Encouraging you to interact with the Shippy Ships mod.
