Navy D-Qual

Naval Academy sail training craft must be commanded by individuals who have obtained their D-qualification.   There are two levels, a D-CS or Coastal Skipper, and D-OS or Offshore Skipper.   A D-CS typically acts as an Executive Officer (XO) or second in command for offshore passages.  They can also command a vessel during short passages in inland or near-coastal waters.  The D-OS commands an offshore capable sailboat during continuous offshore passages in unfamiliar waters in all conditions.  VOST coaches, OSTS volunteer instructors, and Midshipmen may earn these qualifications through their respective programs.  

The qualification has several elements.   Candidates must log time on the offshore vessel in a training capacity.  Specific skills must be signed off by their training instructor for different levels of each qualification.   The instructor and program director must recommend them, and each candidate must pass several written tests.  Attendance at a Safety at Sea Seminar is required (volunteers attend free of charge).   First aid and CPR qualification is also required and provided by each offshore program.   Once qualified, there are refresher tests that must be maintained. 

The tests are taken online, with the exception of the navigation exam, which includes written questions and plotting on a chart.
