About Us

Northport Bay Boat Yard was founded in 1965 by Frank and Marilyn Koral. With one storage and service building and a 20-ton overhead hoist, the Korals began their business in the historic village of Northport.

In the late seventies, Les Valmadre purchased the boat yard. He began improvements by increasing the storage capacity and began building sailboats.

In 1984, the Holtz and Thyer families acquired the boat yard. They concentrated on expanding storage to include mast-up outdoor and heated facilities. Over the next 25 years, the boat yard transitioned from storing 85 boats to handling over 350 boats up to 75 feet in length.

In 2010, present owners, Don and Rae Ellen Thyer purchased the neighboring Gull Island Marine. The acquisition brought additional heated and unheated storage facilities to the boat yard, as well as a heated workshop for maintenance and repairs.

Northport Bay Boat Yard is also a proud sponsor of America's Great Loop Cruisers Association (AGLCA) and welcomes many of the AGLCA boats for storage each year.

Because of the boat yard's rich history and loyal customer base, the Northport Bay Boat Yard staff recognizes the first Saturday in August as Customer Appreciation Day. The day is celebrated with fun workshops and games, food, music, and dancing. On this day, we take the time to thank our customers for their continued patronage and enjoy meeting with our newest customers. We hope to see you on this day, too.
