Seamoth Hull Upgrades

Crafting path, fragments and depth ratings for every Seamoth hull upgrade module.

Last refreshed 2026-05-18

The Seamoth is the workhorse submersible of any Subnautica 2 playthrough. Push its crush depth before pushing your luck.

Pair the Mk II hull with the Cure-All Reaper Strategy route to survive the Crash Zone descent.
