Seamoth

The Seamoth is the smallest submarine-type vehicle, and is also the second fastest of the vehicles with its top speed of 25 Knots or 12.7 m/s (46 km/h).

Overview
Upon entering the Seamoth, the player's Oxygen stores will be replenished. This enables the player to dive into deeper areas of the ocean that are not easily accessible by swimming or by using the SeaGlide.

The Seamoth has an energy supply that needs to be maintained by either docking the Seamoth with the Cyclops submarine or by replacing the power cell on its back. On one full charge, the Seamoth can travel approximately 10650 meters (106.5m per percentage of energy) before the power cell must be replaced. 1% of the submersible's energy is expended for every 18 seconds that the player remains in the vehicle, even if the player is not in motion during that time.

Its health—which is separate from the player's own—can decrease if it is attacked by hostile creatures or crashed into objects in the environment. This damage can be repaired via the welder tool, if the player has one. However, once its health bar reaches 0%, the Seamoth will be rendered irreparably inoperable.

In the future it will be able to dock to the Moon Pool Seabase module.

Influence of Depth
Note: Currently (June 2015), the developers disabled the Seamoth's crush damage until depth upgrades are implemented.

The Seamoth has a safe depth of 125 meters, and a crush depth of 225 meters. The on-board AI will state "CAUTION: Passing safe depth" when below 125 meters, and a HUD message will appear with "WARNING: Passing safe depth of 125 meters. Collision will do damage to hull". However, the Seamoth will still take collision damage above 125 meters.

Below 225 meters the on-board AI will state "WARNING: Maximum depth reached, hull damage imminent", and a HUD message will appear with "WARNING: Approaching crush depth of 225 meters. Hull damage imminent! Ascend ASAP". Below that the Seamoth will take hull damage at a constant rate of about 7% per second.

Dangers
Currently, the only dangers to the Seamoth are Reaper Leviathans, Bone Sharks, Crashes, and passing the crush depth. The Crashs seem to be the most dangerous, as they can destroy the Seamoth with only one launched Crash.

Recipe
The Seamoth can be crafted by the player using the Constructor.

However, you will first need to find a Seamoth Fragment and have it analyzed using the Fragment Analyzer.
