That would stink because with the intel gear you would be limited as to where you could go while on ship.
Those were no liberty port cruises, from what I gleaned. They were full of spooks in intel collection mode, very hush-hush. The crew would not discuss their other missions, not to us frogmen or other embarked troops. My understanding is they would typically spend on the order of 3 months driving “gator squares” in the same patch of ocean, fair or stormy, summer or winter. They were an optimum “modular platform” to pull the duty, as long as you totally disregarded the human factor in terms of sea-keeping and a horrible motion.
Not if you were an intel guy with need to know TS CW clearance on a self-designed special mission. HEH.
