Yep. Confirm that NY still requires the registration sticker and associated fees. I was required to document my boat by my lien holder. They want to be able to make first claim and recover to the boat if there are any issues, like theft, etc. It helps secure the collateral. Relative to my comment about hailing ports. There was a question about trying to find the most advantageous place to register the boat based on state tax structures. If you have a boat documented and the hailing port is one state while it physically is located in another, it may draw some additional scrutiny relative to payment of taxes. Over the years I have heard of tax collectors walking the docks to ensure they get their payments. Also, I have heard (I don't know for sure) that some states require boats to be registered in the state based on how long it's located there. ie, if a boat owner lives in NJ the vessel is berthed in South Carolina for over 45 days (just an example!), SC may require the boat be officially registered there.
