Connecticut lets you renew most boat registrations online through the DMV portal, but not all boats may have access to

You can renew your Connecticut boat registration online if your vessel is currently registered in Connecticut, you have no outstanding violations or liens, and your boat has not changed ownership or physical characteristics since the last registration. The Connecticut DMV's online system handles renewals through its website portal. The process takes about 10 minutes, costs the same as renewing in person, and you receive your new registration by mail within two weeks.

Not every boat can renew online. If your registration has lapsed for more than a year, if you have unpaid fines or violations, if the boat has been involved in a title dispute, or if you need to change the registered owner's name or address, you must renew in person at a DMV office or through the mail with a completed form.

Key Takeaways

  • Connecticut boat registrations renew online through the DMV website if the boat is currently registered, has no liens or violations, and has not changed ownership or characteristics.
  • The online renewal fee is the same as in-person renewal and varies based on boat length and type, not a flat rate.
  • You will need your current registration number, the boat's hull identification number (HIN), and a valid payment method to complete the online renewal.
  • If your registration has lapsed for more than one year or you have outstanding violations, you must renew by mail or in person at a DMV office.
  • Your new registration arrives by mail within two weeks of approval; you cannot print it when ready online.

What you need before you start the online renewal

Gather your current boat registration card before opening the DMV website. You will need the registration number printed on the front of the card. You will also need the boat's hull identification number (HIN), which is a unique 12-character code stamped or attached to the boat's hull. The HIN is usually located on the starboard (right) side of the hull near the waterline, or on the transom (back) of the boat. If you cannot locate the HIN, check your previous registration paperwork or the boat's title document.

Have a valid payment method ready. Connecticut accepts credit cards and debit cards for online boat registration renewals. You will also need a current email address where the DMV can send your renewal confirmation and tracking information.

Steps to renew your boat registration online

Go to the Connecticut DMV website and look for the boat registration renewal section. The DMV's online portal is separate from driver's license services, so you will be entering a different system. Click on "Renew Boat Registration" or "Vessel Registration Renewal" depending on the current menu layout.

Enter your current registration number and the boat's HIN when prompted. The system will pull up your existing registration record. Review the information on screen to confirm the boat's description, length, type, and the registered owner's name and address match your records. If any information is incorrect, stop and contact the DMV by phone or visit an office in person, because the online system cannot process corrections.

Confirm or update your mailing address if you have moved since your last registration. This is where your new registration card will be sent. Enter your email address for the confirmation receipt. Select your payment method and enter the card information. The system will calculate the renewal fee based on your boat's length and type. Review the total amount before submitting payment.

Submit the renewal request. You will receive an on-screen confirmation number when ready. Write down this number or take a screenshot. The DMV will also send a confirmation email to the address you provided. Your new registration will arrive by mail within 10 to 14 business days. You can use your old registration card until the new one arrives.

Boat registration renewal fees in Connecticut

Connecticut boat registration fees depend on the boat's length and whether it is a sailboat, motorboat, or other type of vessel. Fees do not have a single flat rate. A motorboat under 20 feet costs less than a motorboat between 20 and 40 feet, which costs less than a motorboat over 40 feet. Sailboats have a separate fee schedule. Non-motorized boats and commercial vessels have different rates as well.

The DMV website will show you the exact fee for your boat before you submit payment during the online renewal process. If you want to know the fee before starting, call the Connecticut DMV at 860-263-5700 and provide your boat's length and type. Fees are the same whether you renew online, by mail, or in person.

When you cannot renew online and must use another method

If your boat registration has lapsed for more than 12 months, the online system will reject your renewal request. You must renew by mail or in person. Contact the DMV to request a renewal form, complete it by hand, and mail it with a check or money order to the address provided on the form. Processing by mail takes three to four weeks.

If you have unpaid fines, violations, or a lien against the boat, the online system will block the renewal. You must resolve these issues before you can renew. Contact the DMV to find out what violations or liens are on file, pay any fines owed, and obtain written confirmation that the issues are cleared. Then you can renew online or by mail.

If the boat's ownership has changed, if you need to add or remove a co-owner, or if the boat's physical characteristics have changed (such as the engine being replaced or the hull being repaired and re-identified), you cannot renew online. You must visit a DMV office in person with the boat's title, a bill of sale if ownership changed, and proof of the physical changes. An agent will update the registration record before processing the renewal.

What happens after you submit your online renewal

The DMV processes online boat registration renewals in the order they are received. Your renewal is not final until the payment clears and the DMV approves the request, which usually takes two to five business days. During this time, you can continue to operate the boat using your old registration card. Do not discard it until the new one arrives.

If there is a problem with your renewal—such as a payment failure or a discrepancy in your information—the DMV will contact you by email or phone using the contact information you provided. Check your email regularly during the processing period. If you do not hear from the DMV within a week, you can call 860-263-5700 to confirm your renewal was received and processed.

Once approved, your new registration card will be mailed to the address you provided. The card is valid for one year from the expiration date of your previous registration. You do not need to do anything else. When the new registration arrives, store it in a waterproof container on the boat or keep it with your boating documents at home.

Frequently Asked Questions

Can I renew my boat registration if I just bought the boat?

No. The online system only works for boats already registered in Connecticut under your name. If you recently purchased the boat, you must first register it as a new vessel, which requires an in-person visit to a DMV office with the bill of sale and the previous owner's title. Once the new registration is issued, you can renew it online next year.

What if I do not have the boat's HIN?

Contact the Connecticut DMV before starting your online renewal. The HIN is required to access your registration record in the system. If you cannot locate it on the boat, the DMV can look it up using your registration number and boat description, but you may need to call or visit an office to do this. Do not guess at the HIN, as entering an incorrect number will cause the renewal to fail.

Can I renew my boat registration if it expired more than a year ago?

No, the online system will not process renewals for registrations lapsed longer than 12 months. You must renew by mail or in person. Contact the DMV to request a renewal form and mail it with payment, or visit a DMV office with your old registration card and payment. There may be a late fee in addition to the standard renewal fee.

How long does it take to receive my new registration card after I renew online?

The DMV mails new registration cards within 10 to 14 business days after your renewal is approved. Approval usually takes two to five business days after you submit payment. In total, expect to receive your new card within three to four weeks. You can use your old registration card on the water until the new one arrives.

What if my payment fails during the online renewal?

The system will display an error message and will not process your renewal. Check that your card number, expiration date, and billing address are correct, then try again. If the payment fails a second time, contact your bank to confirm the card is not blocked for online transactions. You can also renew by mail or in person as an alternative.
