About NMIA
Built By Marina Operators, For Marina Operators
NMIA exists to give marina, boatyard, and marine-service operators a smarter way to insure the businesses they've built around the water.
Our Mission
The National Marina Insurance Association (NMIA) was founded to give marina and boatyard operators an alternative to traditional commercial insurance: a member-owned group captive, built exclusively for the marine industry.
​
Every member of the NMIA Group Captive shares the same waterfront exposures — storm surge, wind, dockage liability, fuel handling, and seasonal fluctuations in vessel storage. That shared understanding, and the shared ownership that comes with it, is what makes the program work. Members become shareholders in the very company that insures them, with pricing based on their own loss history rather than a blended market rate.
Why It's Different
In a traditional shared market pool, well-run marinas quietly subsidize the losses of poorly-run ones. NMIA's group captive model prices members on their own risk instead — rewarding the operators who invest in safety and loss control, not just spreading the cost evenly across the whole market.

The Captive Industry Today
Group captives are an established, well-tested model in commercial insurance — not a new or unproven idea.

What Marina Operators Are Experiencing
A recent Marina Dock Age survey found that 97% of marina operators report significant premium increases, while 54% reported zero claims in the last five years. That gap — paying more without a corresponding increase in claims — is exactly what a group captive is designed to correct.

Meet Dana Swing
Dana Swing holds Master's degrees in Finance and Economics and brings over a decade of commercial lending experience to the marina industry. Through that work, she saw firsthand the financial perils marina owners face — and recognized a proven solution that other industries have used for decades to protect themselves: group captive insurance.
​
Now, as Executive Director of the National Marina Insurance Association (NMIA), Dana is bringing that model to marinas for the first time — giving owners the same collective strength, shared risk, and long-term stability that other industries have relied on for years.
