Mooring Permits in Connecticut: What Your Harbor Management Commission Wants to See
Every Connecticut shoreline town runs its own mooring permit process through a Harbor Management Commission, and each sets its own insurance minimum. Here is what four towns actually require, and how to get a certificate that will not bounce.
Moorings Are a Town-by-Town System
Connecticut law authorises towns to establish Harbor Management Commissions (CGS Chapter 444a), and each shoreline town runs its own mooring field, waiting list, fees, and insurance requirement independently. There is no single statewide mooring insurance rule - the state's role, through DEEP's general permit for harbor moorings, is mostly environmental and navigational; the insurance requirement comes from your specific town commission. That means the answer to "how much liability coverage do I need for a mooring" genuinely depends on which town you are asking about, from Connecticut to the next harbor over.
What Four Connecticut Towns Actually Require
- Bridgeport requires proof of liability coverage of no less than $300,000, submitted with every mooring application and every renewal - not just the first time - with the Bridgeport Harbor Management Commission listed as certificate holder.
- Stamford requires a minimum of $100,000 in liability coverage, with the City of Stamford listed as certificate holder and the city, its officers, agents and employees named as additional insureds, submitted when reserving or renewing a slip or mooring at its municipal marinas.
- Groton requires vessel owners to submit proof of liability insurance along with their mooring permit application.
- Greenwich will not issue a mooring permit until proof of registration, insurance, and a mooring inspection have all been submitted to the Greenwich Harbor Management Commission.
Four towns, four different numbers and processes - which is the point. Do not assume what one shoreline town requires applies to the next.
The Certificate Has to Name the Right Party
The pattern here is the same one that trips people up with marina slip contracts: a certificate that does not name the commission or municipality exactly the way the permit application specifies will come back rejected. Bridgeport wants its Harbor Management Commission as certificate holder; Stamford wants the City of Stamford as both certificate holder and additional insured - two different requirements that look similar but are not interchangeable. What a certificate of insurance actually needs to get right the first time applies just as directly to a town mooring permit as it does to a private marina slip.
Waiting Lists Add a Wrinkle
Several towns run a formal waiting list for mooring space rather than first-come, first-served availability. Old Saybrook's Harbor Management Commission, for example, maintains an open waiting list for North Cove moorings and requires that a permanent mooring be occupied by the listed vessel at least 50% of the time between June 20 and September 20. That kind of usage rule matters for insurance too: if you are insuring a boat against a mooring you have waited years for, make sure the vessel details on file with both the town and your insurer actually match the boat you are keeping there, especially if you have changed boats since you first applied.
Renewing Annually Is Not a Formality
Several towns, Bridgeport explicitly among them, require fresh proof of insurance at every renewal, not only at initial application. Treat your mooring permit renewal the same way you would treat a policy renewal - confirm the certificate is current and still names the right party - rather than assuming last year's paperwork carries forward automatically.
