what does OINCDW stand for

[Mr 100-ton]

this is one of the requirements for 2nd mate

what does the OINCDW stand for???

360 days of service while holding a MMC as 3rd Mate, OF WHICH
180 days of service as OINCDW on Ocean steam or motor vessels,
AND
Service as AB, Boatswain, or Quartermaster while holding an AB
accepted on a 2 for 1 basis for a maximum of 180 days, OR 11.406

I'd say it's a typo, should read: OICNW Officer In Charge of a Navigation Watch.

The proposed change to 46CFR 11.406 will read quite different than what you quoted, BTW.
