Overview
Unlike vehicles, New Hampshire doesn't title boats at all - you get a Certificate of Number and a set of registration decals, full stop, and every registration expires on December 31 regardless of when you bought or registered the boat during the year (so a boat registered in August still expires that same December 31). There's no sales tax on the purchase either, same as cars, so the annual registration below is the entire ongoing cost of boat ownership in New Hampshire.

New Hampshire boat registration FAQ
How much does it cost to register a boat in New Hampshire?
Between $47.50 and $115.50 a year depending on length: a base fee of $24 (under 16 ft) up to $92 (over 45 ft), plus roughly $23.50 in flat state surcharges - lake preservation, public water access, and search-and-rescue fund fees - that apply to every registration regardless of size.
Do I title a boat in New Hampshire like I would a car?
No. New Hampshire only issues a Certificate of Number and registration decals for boats - there's no separate title document the way there is for a motor vehicle. Ownership transfers with a signed bill of sale.
Why does my registration expire so soon after I bought the boat?
Every New Hampshire boat registration expires December 31 no matter when during the year you registered - buy a boat in October and you'll be renewing again in roughly two months. The state doesn't prorate the following year's fee down for a partial first year.
Is it Fish and Game or the DMV that handles boat registration?
The DMV issues the registration and collects the fees; NH Fish and Game's Marine Patrol division handles on-water law enforcement and boating safety, and receives a cut of the fees (the $1 search-and-rescue fund fee) but doesn't run the registration counter.
Do kayaks, canoes, or paddleboards need to register?
Non-motorized kayaks, canoes, and paddleboards generally don't need registration in New Hampshire. Add a motor of any kind - even an electric trolling motor - and registration becomes mandatory regardless of the hull's size.
Is there sales tax when I buy a used boat privately in New Hampshire?
No - the same statewide absence of sales tax that applies to cars applies to boats. You pay nothing on the purchase itself, only the annual registration fee based on length.
