Michigan sailboat registration is handled by the Michigan Department of Natural Resources, not your local Secretary of State office

Sailboats in Michigan fall under a different registration system than cars and trucks. The Michigan Department of Natural Resources (DNR) issues vessel registrations, and the process depends on whether your sailboat has a motor, where you keep it, and whether you own it outright or have a lien against it.

You cannot register a sailboat through your county clerk or the Secretary of State. Instead, you'll work directly with the DNR's Watercraft Registration Unit or submit your paperwork by mail. The registration is valid for three years from the date of issue, and you'll receive a registration number that must be displayed on the hull.

The cost varies based on the sailboat's length and whether it has an auxiliary motor. A sailboat under 20 feet costs less than one over 20 feet. If your sailboat has a motor, you may also need to register the motor separately depending on its horsepower.

Key Takeaways

  • Michigan sailboat registration is issued by the Department of Natural Resources, not the Secretary of State, and is valid for three years.
  • You'll need the sailboat's hull identification number (HIN), proof of ownership, and a completed process form to register.
  • Registration fees depend on the sailboat's length and whether it has a motor; sailboats under 20 feet cost less than larger vessels.
  • You can register online through the DNR website, by mail, or in person at a DNR office, and the registration number must be displayed on the hull.
  • If you have a lien on the sailboat, the lienholder's information must be included on the registration.

What documents you need to register a sailboat

Start by gathering proof of ownership. This is usually the bill of sale, a previous registration certificate, or a manufacturer's certificate of origin if the sailboat is new. If you bought the sailboat from a dealer, they may provide a document stating they hold the title; if you financed it, your lender holds the lien and their name goes on the registration.

You'll also need the hull identification number (HIN), which is a 12-character code stamped or attached to the sailboat's hull, usually near the starboard (right) side at the transom or on the interior. If you cannot locate the HIN, the DNR can help you identify it, but having it ready speeds up the process.

Complete the process for Watercraft Registration (Form REG 3), which you can read from the Michigan DNR website or pick up at a DNR office. The form asks for your name, address, the sailboat's description, the HIN, and whether the sailboat has a motor. If someone else holds a lien, you'll need their name and address as well.

How to register online, by mail, or in person

The fastest route is the DNR's online registration system. Visit the Michigan DNR website, navigate to the Watercraft Registration section, and follow the prompts to enter your sailboat's information and pay the fee by credit card. You'll receive a confirmation number when ready, and your registration certificate will arrive by mail within two to three weeks.

If you prefer to register by mail, print the completed process for Watercraft Registration form, include a copy of your proof of ownership, and mail both to the address listed on the form along with a check or money order for the registration fee. Processing takes three to four weeks from the date the DNR receives your packet.

You can also register in person at any Michigan DNR office. Bring your proof of ownership, the completed process form, and payment. Staff can process your registration on the spot, though you'll still receive your official certificate by mail. Call ahead to confirm office hours and location.

Registration fees and what affects the cost

Michigan charges registration fees based on the sailboat's length. Sailboats under 20 feet cost one amount; sailboats 20 feet and over cost more. The exact fee changes year to year, so check the DNR website or call the Watercraft Registration Unit for the current rate before you submit your process.

If your sailboat has an auxiliary motor (an inboard or outboard engine), the registration fee may be higher. Motors under 10 horsepower are sometimes treated differently than larger motors. If you're unsure whether your sailboat's motor affects the fee, describe it to the DNR staff when you contact them—they can tell you the exact cost before you pay.

The registration is valid for three years. When it expires, you'll renew it through the same DNR system. The DNR does not send renewal notices by mail, so mark your registration expiration date on your calendar or set a reminder.

Displaying your registration number on the hull

Once you receive your registration certificate, the DNR will assign a registration number that you must display on the sailboat's hull. The number is typically painted or attached to both sides of the bow (front) in characters at least three inches tall, in a contrasting color to the hull.

Some sailboats have the number on the transom (back) instead, depending on the hull design. Check your registration certificate for the exact placement requirement. The number must be visible and legible from the water, and it must remain on the sailboat even if you sell it—the new owner will receive their own registration and number.

If the number becomes faded, damaged, or illegible, contact the DNR to report it. You are not required to re-register, but you should repair or repaint the number so it meets visibility standards.

Transferring ownership or renewing a sailboat registration

If you sell your sailboat, the new owner must register it in their name. They'll need the registration certificate you received, proof of their ownership (the bill of sale signed by you), and their own process form. The new owner can register online, by mail, or in person using the same process you used.

When your three-year registration expires, you renew it by submitting a renewal process and the current fee to the DNR. You do not need to provide proof of ownership again unless the sailboat has changed hands. If you no longer own the sailboat, notify the DNR so they can close the registration and you won't receive renewal notices.

If you move to a different address in Michigan, update your registration with the DNR. You can do this online or by contacting the Watercraft Registration Unit directly. Keeping your address current ensures you receive any notices about changes to registration rules or fees.

Sailboats with liens and financing

If you financed your sailboat, the lender holds a lien against it, meaning they have a legal claim until you pay off the loan. When you register the sailboat, include the lender's name and address on the process. The lender's name will appear on your registration certificate.

You can still use and register the sailboat while the lien is active. The lender does not need to sign the registration process, but their information must be accurate. If you pay off the loan, contact the lender to request a lien release letter, then submit that letter to the DNR to have the lien removed from your registration.

If you sell the sailboat while a lien is active, the sale proceeds typically go to the lender first to pay off the loan, and any remaining money goes to you. The new owner cannot register the sailboat in their name until the lien is released, so coordinate with your lender and the buyer to may support the paperwork is handled in the correct order.

Frequently Asked Questions

Do I need to register a sailboat that doesn't have a motor?

Yes. Michigan requires registration for all sailboats, regardless of whether they have a motor. The only exceptions are sailboats under 20 feet with no motor that are used only on private ponds or lakes, but most sailboats on Michigan's public waters must be registered.

What if I can't find the hull identification number?

Contact the Michigan DNR Watercraft Registration Unit and describe the sailboat—its make, model, year, and color. They can help you locate the HIN or may be able to process your registration without it in some cases. Having the bill of sale or previous registration helps speed this up.

How long does it take to get my registration certificate?

If you register online, you'll receive a confirmation number when ready, and your certificate arrives by mail in two to three weeks. By mail, processing takes three to four weeks. In person at a DNR office, staff can process it the same day, but the official certificate still arrives by mail.

Can I register a sailboat I'm buying from out of state?

Yes. Bring the out-of-state registration or bill of sale to prove ownership, then register it with the Michigan DNR using the standard process. You do not need to transfer a title through the Secretary of State—the DNR registration is your proof of ownership in Michigan.

What happens if I don't renew my registration before it expires?

Your sailboat cannot legally be operated on Michigan waters. If you're stopped by a conservation officer, you can face a fine. Renew as soon as you realize it has expired by contacting the DNR; they can backdate the renewal to cover the gap, though you may owe a late fee.
