Coast Guard Petty Officer 1st Class Jeremy Speedy, a diver with the Coast Guard Regional Dive Locker East (RDLE), gives the "OK" signal after completing a hull inspection of the USCGC Kennebec (WLIC 802) in Portsmouth, Virginia, Aug. 27, 2024. The “ok” signal can be used as both a question and an answer, and it’s also the proper response to any hand signal directed your way to acknowledge that it has been seen and understood.
