The Vidar is a ship meant to explore systems. It isn't big enough to carry the people, instruments and supplies needed to colonize a planet.
actually it is larger than a crovette and the neary 2/3 of an orion in lengh - so much for the size
also with a small tbl. and modelediting (I don't know the if later is actually needed) the "CryoPods" could be "DropPods" ... so think of the first wave of supplies just being dropped out of orbit like small meteroids - on impact creating a crater that would make an ideal place to found the colony in (also this things are larger than any container save for the TC-TRI/Meson Bomb)
and the colonization of a planet would rather begin with building infrasturcture than unloading people on the planet - so at first a large quatity of supplies and a large population are senseless (not too many would sign up to leave the conforts of an interstellar civilisation for running on a planet which in near pure wilderness)
than further supplies and colonists would arrive in freighters and transports on the already spaceport of some sort
---> no need for rediculusly over-sized colony ship like the one from ITDOH
(while that ship was more a colony on a ship than ship to colonize planets)
