The Stranded Deep 4-Player Mod is a testament to modder dedication, enabling a mode the developers did not. It provides dozens of hours of shared survival if the group is patient, technically adept, and willing to restart sessions frequently.

Always verify mod compatibility with your game version, and accept that in this modded experience, the ocean—and the netcode—may always be against you.
