Windward and leeward are still commonly used in my experience. Also, there's a fun additional distinction for forward and aft, which is that they tend to refer to locations within the vessel. Ahead and astern are used to refer to locations outside of the vessel. After about 8 years of sailing fairly regularly with various crews, I still get many of the terms mixed up. For instance, stanchions and shrowds are terms that are useful, but they never seen to come to mind when I need to communicate them.
