Extending a polygon outwards?

Hi everyone

I was wondering if there was a way to extend a polygon outwards?
What I have is a polygon of a country with 12 different regions within it and the edge (coast) is lined with these various regions (no region overlaps). I wish to extend these polygons 30m past the coastline. However I can't use a buffer(with the outside only option) because then the regions overlap and it's impossible to clip overlaps when at different points of the coastline, I have different regions overlapping. I also can't use the edit vertices option because there are so many vertices that I would have to individually click and drag outwards to the same distance. Is there a function that can take my polygon and extend the polygon outwards over the coast?
