How to Register a Boat in Alabama: What You Need, What It Costs, and How to Get It Done

You just got a boat in Alabama. Or maybe you've had one for a while and realized you're not sure if you've done everything right. Either way, you need a current registration before you put that vessel on the water.

Alabama requires all motorized boats to be registered through your county probate office or the license commissioner's office. The process is straightforward, the fees are reasonable, and as long as you show up with the right documents, you can typically walk out the same day.

At Stryker T-Tops, we help boaters get the most out of their time on the water. We sell T-tops, center console accessories, and gear built for anglers who fish hard and spend long hours on the Gulf or inland lakes. We know how Alabama's boating world works, and we're happy to share what we know. Browse our boat T-top catalog or contact us anytime.

Which Boats Must Be Registered in Alabama?

Alabama registers all mechanically propelled vessels, sailboats, and boats offered for hire. That includes everything from small aluminum fishing boats with trolling motors to large center consoles running twin outboards on Mobile Bay.

Human-powered boats like kayaks and canoes do NOT need to be registered unless you add a motor to them. The moment you bolt on even a trolling motor, the vessel becomes subject to Alabama's registration requirement. This catches a lot of paddlers off guard.

Does Your Boat Need a Title?

Alabama added a titling requirement for certain vessels beginning January 1, 2024, under Act #2022-144. Whether your boat needs a title depends on when it was built and how long it is.

Boats built after December 31, 2023, that are under 18 feet long are required to have a certificate of title only if powered by an engine of 75 horsepower or more. Boats 18 feet and longer that are under 26 feet do not have a mandatory titling requirement. Boats 26 feet and longer can voluntarily apply for a title, but it is not mandatory.

If your boat was built before 2024, you do not need a title to register it. Just bring your bill of sale and any previous registration documents.

Title applications are handled through the Alabama Department of Revenue (ALDOR). The title fee is $25. If you need to replace a lost title, the replacement fee is $15. You complete titling before or alongside your registration - not after.

Alabama Boat Registration Fees by Vessel Class

Vessel Class	Boat Length	Typical Fee Range*
Class I	Less than 16 ft	$20 – $30
Class II	16 ft up to 26 ft	$25 – $35
Class III	26 ft up to 40 ft	$75 – $85
Class IV	40 ft and above	$100 – $110

*Fees vary by county. First-time registrations also require sales tax on the purchase price, collected at local rates. There is an additional $25 title fee when titling is required.

Where to Register Your Boat in Alabama

Registration is handled at your county probate judge's office or the license commissioner's office. This is the same office where you'd register a car. Walk in, bring your documents, and they'll process everything on the spot.

Not a resident of Alabama? You can register at the Marine Police Division office in Montgomery. Dealers and rental operators also go through the Marine Police Division regardless of where they're located in the state.

Some counties, including Baldwin County on the Gulf Coast, also allow online renewals through their probate office websites. Check with your specific county to see what's available.

Registering a New Boat Purchased from a Dealer

If you just bought from a dealer, the registration process is clean. Alabama gives you a 72-hour grace period after purchase to get registered. Don't wait longer than that.

Here's what you need:

• Bill of sale from the dealer
• Manufacturer's Statement of Origin (MSO) — the dealer provides this
• For boats requiring a title (built after 2023, under 18 feet with 75+ hp engine): a completed title application submitted to ALDOR
• Payment for registration fees and any applicable sales tax

If two people are buying the boat together and the bill of sale lists both names joined by "AND" or "&", both buyers must be present with valid ID. If the names are joined by "OR", only one owner needs to show up.

Registering a Used Boat in Alabama

Buying used has its own set of requirements, and the rules tighten up depending on where the boat is coming from.

If the boat is currently registered in Alabama, you have 15 calendar days from the date of purchase to transfer the registration into your name. If the boat's registration has already expired, there is no grace period at all. You must register it before it touches the water. Bring the current registration certificate and the bill of sale to your county office. The transfer fee is $5, plus sales tax on the purchase price if you haven't already paid it.

Buying from out of state? You'll need the last out-of-state registration certificate and a bill of sale. All boats coming from out of state, and all boats that have never been registered, must have a photo of the hull identification number (HIN) for verification before they can receive an Alabama registration number. No transfer fee is charged on out-of-state boats; you'll simply be issued a new Alabama registration number.

What Is the Hull Identification Number and Where to Find It

The Hull Identification Number (HIN) is a 12-digit number that identifies your specific boat. By federal law, every vessel manufactured after 1972 must have one, and it's required on your Alabama registration certificate.

You'll typically find the HIN on the outside of the stern, on the right (starboard) side, just below the gunwale. It's usually stamped or molded directly into the hull material.

If you can't locate the HIN on your vessel, don't guess. Contact the Alabama Marine Patrol at 1-800-272-7930 to get a state-assigned HIN before you try to register. You cannot register without one, and making one up creates serious legal problems. The HIN inspection requirement also applies if your county processes a boat title.

How Boat Registration Renewal Works in Alabama

Alabama uses a staggered renewal system. Your renewal month is based on the first letter of your last name, which is the same way vehicle registrations work. You renew once per year, and fees are not prorated. That means if you register a new boat in July and your renewal month is September, you'll owe the full registration fee again in September. Plan accordingly.

You can renew in person at your county probate or license office, by mail if your county offers it, or online through your county's renewal portal. Some counties use altagrenewals.com. Others have their own portals. When renewing online, you'll typically need your renewal notice or your Alabama driver's license number and boat registration number.

There are no late penalties on boat registration renewals in Alabama. That said, operating an unregistered vessel is still a violation, so staying current is worth it.

Boat Registration vs. Boat Operator Certification: Know the Difference

These are two completely separate requirements, and confusing them can leave you with a ticket.

Boat registration covers the vessel. It proves the boat is legally documented and tied to an owner. Operator certification covers the person driving the boat. Alabama requires anyone age 12 and older who operates a motorized vessel on state waterways to hold a valid operator certification.

To get certified, you'll need to complete a boating safety course approved by the Alabama Law Enforcement Agency (ALEA) Marine Patrol Division. Operators under 14 may only hold a Vessel Learner License and must be accompanied by a licensed operator who is 21 or older.

You need both registration and operator certification to be fully legal on Alabama water. One does not substitute for the other.

What Happens If You Move to Alabama with a Boat Already Registered Elsewhere

Alabama does not charge a transfer fee when you bring a vessel in from another state. You'll be issued a new Alabama registration number, and no fee is applied for the out-of-state transfer itself.

Bring your most recent out-of-state registration certificate and a photo of the HIN to your county probate or license office. Sales tax may be due if you haven't paid it in your previous state. The county office will walk you through what applies to your specific situation.

If your boat falls into the titling requirement (built after 2023 and under 18 feet with 75+ horsepower), you'll also need to apply for an Alabama vessel title through ALDOR before registration.

A Few Things That Catch New Owners Off Guard

Alabama's boat registration system is county-based, which means fees, office hours, and online availability vary by location. What's true in Baldwin County may not match Shelby County. When in doubt, call your specific county's probate office before you make the trip.

Sales tax on boat purchases is collected at the county level, at the same rates that apply to vehicle purchases. If you bought from a private seller and didn't pay sales tax at the time of purchase, you'll owe it when you register. There's no way around it.

A marina or storage facility address is not an acceptable domicile for registration purposes. You register in the county where you live or where the boat is permanently kept, not where it's stored seasonally.

And one more thing: if you add a motor to a previously non-motorized boat, you now have a registration requirement. A trolling motor on a kayak, a small outboard on a canoe, both count.

Frequently Asked Questions

How long does it take to register a boat in Alabama?

Most first-time registrations are completed the same day you visit your county probate or license office, assuming you bring all required documents. Online renewals are processed quickly as well, though sticker delivery by mail can take a few weeks, depending on your county.

Can I register my boat online in Alabama?

Online registration is available for renewals in many counties, but first-time registrations typically must be done in person at your county office. Some counties, like Baldwin County, offer online renewal portals through their own sites. Check with your specific county to confirm what's available.

What if my boat has never been registered anywhere?

If your boat has never been registered in any state, you'll need to fill out an affidavit (sometimes called a Pond Use Affidavit or similar) confirming prior non-registration. You'll also need to provide a photo of the HIN and any applicable bill of sale. Your county probate office will walk you through the process.

Get on the Water with the Right Gear

Getting your boat registered in Alabama is one of those tasks that looks more complicated than it actually is. Show up to your county probate office with your bill of sale, your proof of HIN, and your payment, and you'll typically be done in under an hour.
