Having areas end exactly at the waterline seems to be  a common 
reason for mapping mistakes and broken coastlines so I don't see 
that it would be the easiest solution.

Also it is almost never so that the rock would end exactly at the 
waterline and even if you do not know exactly how far it extends 
underwater a good guess is still better than inserting wrong 
information.
