Waveskimmer

The waveskimmer was a small repulsorcraft used by Imperial aquatic assault stormtroopers.

Characteristics
The waveskimmer was able to move under sea[1] and surf on waves.[1][3] It was a single person vehicle[1], but two people could manage to ride the vehicle.[3]

It carried no weapons, but the seatroopers would fire their infantry weapons while driving the waveskimmer.[1] However, a version with a mounted sonic blaster was used in Alluuvia.[2]

Twinpod paracapsules could be used to drop two waveskimmers and two seatroopers from a starship in orbit.
