Jetski?
Yes, then we should return to the ship after our exploration and then be able to drive into a kind of flood chamber.
For example, as soon as we approach our ship again, a hatch opens on the left or right side and we can drive the jetski inside.
The jet ski docks in the hatch and turns back to the starting position with us. Then we can get off the jetski.
That would be awesome, developers. ๐๐๐
