State routinely goes through lists of Coast Guard documented vessels and assumes that any with a New York
hailing port and/or a mailing address within New York State are tax scofflaws. I went through the same thing due to having a NY address and hailing port, even though my boat
has never been in New York state. By the way, if you are a resident sales or use tax is due as soon as your boat
enters New York waters, no matter for how short a period. So, keep it out of the state unless you are willing to pay.
