Connecticut Boat Registration Renewal: DMV, DEEP and AIS Checklist (2026)

Quick Answer: How Connecticut Boat Renewal Works

Connecticut boat registration is listed as a 1-year registration in current site data. DMV handles registration services, while DEEP is central to boating rules and safety certificates. Start with the DMV registration service for renewal, but keep DEEP boating requirements in mind if you operate the vessel.

DMV vs. DEEP: Who Handles What?

Connecticut can be confusing because boat owners see both DMV and DEEP in the process. DMV is the registration and title service channel. DEEP is the boating authority for safety, certificates, enforcement context, and waterways guidance.

For renewal, follow DMV instructions. For operating rules, Safe Boating Certificate questions, PWC operation, and boating education, use DEEP resources or the boater education requirements guide.

Renewal Checklist

Have your current Connecticut registration, owner identification, vessel information, payment method, and any renewal notice ready. If the boat is used on inland waters, review current Aquatic Invasive Species decal or stamp requirements before assuming the registration renewal alone is enough.

If you recently bought the boat, moved from another state, changed owners, or changed vessel details, handle those updates before treating the transaction as a simple renewal.

Cost and Title Notes

Connecticut registration fees vary by boat length, age, and hull material in current site data, and an AIS decal may apply for inland waters. The state data also lists a $25 title fee and a 6.35% sales tax rate.

Because Connecticut fees are more variable than simple flat-fee states, use the Connecticut boat registration page for the full state overview and the fee calculator for planning.

Frequently Asked Questions
