N.Y. Comp. Codes R. & Regs. tit. 15, § 104.5
(a) Section 79-b of the Navigation Law provides that the Commissioner of Parks, Recreation and Historic Preservation establish a boat anti-theft program. The identification of boats, including the assignment of hull identification numbers to boats which do not have them, is an integral part of any such system.
(6) The Commissioner of Parks, Recreation and Historic Preservation need not accept any application for assignment and/or affixing of a hull identification number for any boat which is a 1972 or older model boat or any boat which is a 1973 model manufactured on or before November 1, 1972 or, if no model year is known, which can reasonably be assumed to have been manufactured or assembled on or before November 1, 1972.
(c) Registration of boats without hull identification numbers.
The registrations of currently registered boats which do not have hull identification numbers will continue to be renewed. However, a boat manufactured after November 1, 1972, shall not be issued a registration upon a transfer of such boat unless a hull identification number has been assigned and affixed in accordance with subdivision (b) of this section.
(b) Assignment of hull identification numbers.
