It all depends on what you want to do. It is up to you the amount of time you dedicate to it, we do have monthly meetings but are not mandatory... But it is good to attend to be aware of opportunities and to plan things. I for one opted for boat crew/patrols and now got a Coxswain rating, and do spend some time underway on patrol. I also teach boating safety classes, do vessel inspections, dealer visitations, and career days. I am a teacher full time but have plenty of free time to dedicate to it. I do know a few active duty coasties who are part of the Aux, even CO's...
