The seaglide will increase your effective exploration range. For your safety please pack supplies for long journeys, and always stay within 5km of the nearest lifepod or habitat.

The Seaglide is a handheld deployable vehicle which increases the user's top speed when held. It can be crafted by using the Fabricator. The Seaglide occupies six slots in the player's inventory. It has a top speed of 11 m/s (24.6 mph, 39.6 km/h, 21.4 knots).

The Seaglide consumes energy when used, and as with all other vehicles, it's rendered unusable once its energy reserve is depleted. The empty Battery can be replaced with a new one using the R key to select a replacement from the players held batteries. On a full charge, the Seaglide can travel approximately 3800 meters.

The Seaglide possesses a 3D map of nearby terrain and a flashlight that can be turned on and off interchangeably through 5 different settings. The flashlight uses energy while active. Toggling the flashlight (using the right mouse button) three times consecutively will toggle the map on or off. Despite the flashlight being useful in certain situations, the brightness and area is less than the regular flashlight.

The Seaglide's speed is fixed and is not affected at all by the player's Fins, Suit, and Oxygen tanks like the Standard O₂ Tank will not slow it down. The Fragments can be found in the Kelp Forest and in Safe Shallows.

While wearing Swim Charge Fins, as long as the player remains moving the Seaglide will slowly gain charge rather than losing it, allowing for effectively infinite use. One recommendation to maximize this feature is to switch a low or depleted battery from another tool with the battery on the Seaglide.


The Seaglide can be carried in the inventory and must be assigned to the toolbar to be used. When used, it drastically increases the player's swimming speed. It doesn't have a depth limit, and thus functions anywhere the player goes underwater. However, it cannot be used at or above sea level. The 3D display also won't work above water, only the flashlight. The player will swim at normal speed until they submerge. Therefore swimming below the sea level is superior to swimming at the sea level.

The top speed is 10 m/s, making it only slightly slower than the Seamoth, and slightly faster than the Cyclops at "ahead standard".

The Seaglide is one of the most used tools in Subnautica, especially early on.

  • The Seaglide works in the same way as a handheld DPV (diver propulsion vehicle).
  • There is a removed, upgraded variant of the Seaglide named the Powerglide, which traveled three times faster than the Seaglide.
  • In early builds, the storage unit on Lifepod 5 contained a free Seaglide at the start of the game.
  • With full acceleration, a Seaglide can jump into the moonpool without using the ladders.
  • In the early prototype stage of the game, it was known as the Seajet.[1]
