Extract By Mask - Image Analysis

I am trying to extract information from a Raster Dataset that does not intersect with a feature dataset over the Gulf of Mexico. [ATTACH=CONFIG]12774[/ATTACH]

Both shapefile and raster are in the same projection. I have attempted to do this using the Mask function in Image Analysis however this does not extract any information. Rather it leaves an empty raster of 40mb in size (no attribute table) and exporting that dataset does nothing. I am wondering if the high resolution coastline is too complicated? Does anyone have another method to extract information outside of the polygon? IMO it is strange that vector data has erase and intersect functions but raster datasets have extract by mask but no erase equivalent.
