The Hull Reinforcement is an upgrade module that can be crafted in the Vehicle Upgrade Console.

It provides the Seamoth and the Prawn Suit a permanently hardened chassis before collision, eliminating damage under normal conditions.

Defense Value

  • 1 Hull Reinforcement -50% damage taken
  • 2 Hull Reinforcements -75% damage taken
  • 3 Hull Reinforcements -87.5 damage taken

Damage is only reduced from collision with terrain. Other sources of damage such as aggressive fauna do full damage.
