Scout Ray or Haul: chassis scans, recipes and docking
Quick answer
Choose Scout Ray for travel and Haul for cargo trips. Chassis are built at the Vehicle Fabricator; upgrade modules use the Modification Station. One chassis can be attached at a time.

At the Tadpole Pens, follow the interior passage to the Moonpool and scan the Scout Ray. Finish the Pens access steps first if you are still locked out.

On screen: At about 151 m the diver passes through a round tunnel into a long windowed room, where a finned Scout Ray chassis rests by the wall; a scan prompt appears over it and a Scout Ray Chassis notice shows at the left.

Scan the wreck in Ruby’s cave near the Mk. 1 data card. An unmodified Tadpole must stay above its crush depth.
East of the Research Base, find the hanging Cicada wreck near Singh’s black-box signal. Search the lower shelf for the chassis leaning against a railing.

On screen: From a Tadpole at about 218 m, a large grey chassis lies tilted on a rocky shelf next to a yellow railing; the diver swims out and at 220 m holds the Scanner over it as it lights up in a blue-green outline.

Shacknews reports another scan about 180 m northeast of that shelf, on a rocky plateau. The deeper green-pool Metal Farms area provides another reported option if the plateau scan does not complete your blueprint.
Check the blueprint’s scan count before returning to the Vehicle Fabricator.
Sources describe Haul cargo capacity differently, so this guide does not promise a slot total. Check the actual containers in your build before planning a full-load return.
Hotfix 2 also fixes docking checks blocked by the Tadpole’s own geometry and destroyed vehicles with attached chassis failing to return inside bounds. Check the update before expanding a base solely to address an orientation bug. The notice does not guarantee recovery of previously lost cargo.
Detach the current chassis using the displayed interaction before fitting the replacement.
Attach the new chassis in open space. Test the approach to the dock before filling the cargo bay.
If docking reports insufficient space, enlarge the room and Moonpool clearance and remove obstructions. Current builds reject blocked docking.
Before a co-op departure, check power, hull and every rider’s oxygen. Hotfix 1 corrected oxygen depletion for powered Tadpole and Haul riders.
