Winter Boat Storage

Protect Your Vessel.

Secure Off-Season Boat Storage

Winter Boat Storage at Cedar Island Marina

Cedar Island Marina is one of the larger full-service boat yards in Connecticut, offering secure winter storage in a well protected basin, just minutes from Long Island Sound. Our 35 ton lift can haul boats up to 60′ depending on beam and weight.

Our winter program is designed to keep things simple. You can haul out, winterize, store, service, and recommission your boat all in one place. The off-season is also the best time to tackle upgrades, repairs, painting, and mechanical work, so everything is ready to go when spring comes.

With an experienced, on-site team, your boat is looked after throughout the winter. We stay current with new products and technology each year so we can continue to offer reliable, up-to-date service. Year-round customers receive an extra discount on fuel

Expert Boat Yard in Long Island Sound for Boat Repairs & Marine Mechanics

Our service team has extensive experience in paint and fiberglass work, from small cosmetic repairs to more involved structural projects. Whether it’s addressing dock rash, stress cracks, or full gelcoat restoration, we take a careful, methodical approach to matching finishes and restoring the integrity of the hull. The off-season gives us the time and conditions to do this work properly, so results hold up not just visually, but over time.

On the mechanical side, we handle everything from routine maintenance to more complex diagnostics and repairs. Engines, generators, and onboard systems are serviced with an emphasis on reliability, not shortcuts. Because all of the work is done on-site, communication is straightforward and issues can be addressed early, which helps avoid surprises when it’s time to get back in the water.

Full-Service Connecticut and Boat Yard

Winter storage at Cedar Island Marina is built around consistency and attention to detail. Cedar Island Marina is one of the largest boat yards in Long Island Sound and the largest in Clinton, CT. From the moment your boat is hauled, it’s handled by the same experienced crew who know how to properly block, secure, and protect vessels of all sizes. Our yard is organized for accessibility and efficiency, so service work can be completed without unnecessary delays, even in the middle of winter.

We also focus on making spring as easy as possible. Because your boat is already on-site, commissioning, detailing, and any final service can be scheduled ahead of time, helping you avoid the typical early-season rush. When launch day comes, everything is ready to go, so you can get back on the water without the usual stress of coordinating multiple vendors or last-minute work.

Convenient Clinton Location

Located in Clinton, Connecticut just minutes from I-95 and Long Island Sound, our boat yard offers easy access for owners and contractors. The protected harbor setting makes hauling and launching efficient and stress-free in both fall and spring.
