I've got a little experience in this area. A NOTAM is a "Notices to Airmen" and related to flight rules. There is an equivalent for "notices to mariners as well. You will be on the water
, the east coast
is littered with "W" or whiskey areas, these are "warning" areas, again for flyers. As I've operated in most of these on the east coast the activity below is of little interest to the aviation. There are rules about avoidance from vessels, persons etc below; 1500 feet, 3nm or something like that, common sense approach just stay away from boats below you. Never violated those...no honest. There are also P Prohibited and R Restricted areas but likelihood of running into those is slim. These are generally along the coast and are being used by Navy
servicemen in training. ALL will be well marked and should be on your basic charts
. You find those in S Virginia, Northern North Carolina
; maybe related to SEAL training. Land based stuff doesn't need miles and miles of space.
Bottom line, do what I do, ignore all that stuff, big-sky/big sea theory. You'll be fine.
