different scenarios , different rules.
if you are in your boat, the only laws that apply to you are the 250 foot rule amd weaher you are in a SPECIFIC area listed in the back of the guide as a NO HUNTING area.
if you are on land you need to be below the MEAN HIGH WATER mark as well as the previous two rules mentioned.
on rock outcroppings , I am not sure, because most LANDS are owned by someone and even a 30ft x 40 foot rock is usually someones property....but if it is out in open water , doesnt have any marking as to trespassing, Id go ahead and hunt it until someone fussed.
you cant hunt bufflehead, HENSONLY has a special permit that allows only him and his buddies to shoot them, but again he cant be everywhere, so i doubt he'd catch you!!
otherwise goldeneye, bluebills, some canvasbacks, some Ruddy Ducks and a few species of mergansers will also be encountered all along the CT coast in the winter... have at em
