If you have specific questions about New York's registry for salt water, here is the phone number for the NY EnCon Police office that covers their marine district. 631-444-0460

I would suggest giving them a call (I don't have an email address for anyone down there) and asking them directly. I don't want to give you information based on my understanding of NY law and give you the wrong info or interpretation. The info I posted at the top of this thread was provided by CT DEP Marine Fisheries.
