Default Starboard Rio query?

Hi all :>)
Just bought a brand new RIO, but when I got it home I noticed two small holes on the underside in the center of the board,
These machined holes are about 5mm diameter and an inch apart, they are also an inch deep.
what are they for?
should they have some kind of bungs in them?
Surely they must have an effect on performance.

Any help gratefully received.
