What happens if you have a 1G acceleration ship and it lands on a 10G world?
My answer:
You just take off. Once Contra-grav is there, the field surrounding your ship is whatever gravity you want and so therefore you can take off and land without issues since you have nullified the local gravity. Escape velocity and mass become irrelevant with Contra-grav technology.
