You could also look at some great CG footage at coastguardchannel.com or cgclips.com .
I have never been at a Station, but when I was a non rate I was on a ship that had three small boats (CGC Polar Star) and as a boat crew member you were in charge of doing what ever the Coxswain needed you to do.....Lookout, rigging/assisting with towing, ect., you had a set of quals to get signed off to be qualified as a boat crew member. One being qualified in First Aid/BLS. Thats just a small tid bit....I am an HS now so, I bet there is a BM or an MK around here that could tell you. Good Luck!
what would i be doing as part of a small boat crew?
Go to www.uscg.mil click on units and check out the different units. Most will have a website telling what they do for their area of operations. Here one for an example. http://www.uscg.mil/d9/grumil/ Each is different in what they do based on the area the patrol. CPO Kalbach
