Shop productsVisit the shopOhio’s largest Lake Erie island
Kelleys Island is the largest American island in Lake Erie, according to the Ohio Department of Natural Resources. Kelleys Island State Park covers nearly 700 acres and has a double-lane boat launch with a courtesy dock on the north shore, along with the Glacial Grooves State Memorial. The Kelleys Island Ferry lands at Seaway Marina Port, about four miles north of Marblehead, and island marinas, including Craft’s Lakeview Lane Marina, offer transient dockage.
Island life means boats left at the dock, cottages closed up for the winter, and damp lake air on everything. The jobs that matter most are mildew prevention and cleanup, vinyl and canvas care, and a simple routine for keeping the gelcoat protected through the season.
From the island, our shop is a ferry ride and a short drive away. The Kelleys Island Ferry runs vehicles and passengers to West Main Street in Marblehead, about 19 minutes from us. The Jet Express connects Kelleys Island with downtown Sandusky.

Kelleys Island season notes
For boats and cottages that spend the off-season on the island.
Closing up for winter
- Clean before you close up. Dirt, food and sunscreen on vinyl and fabric give mildew something to grow on.
- Treat clean, dry soft surfaces with a mildew preventer, and set out a dehumidifier in closed cabins and lockers.
- Seal the gelcoat before covering the boat, so it doesn’t sit unprotected all winter.
Opening up in spring
- If you see mildew in the spring, remove it first, then treat the area to slow regrowth.
- Bring a short list on your first mainland trip of the season. It’s easier than making several ferry runs.
- If the gelcoat is chalky, test-spot polish before you decide whether a full compound job is needed.
