About Us


For over 40 years, family owned Great Northern Docks has built its reputation on superior quality products and friendly, knowledgeable customer service. Located in Maine, where lakes, rivers and coastline abound, our commitment to convenient access in aquatic environments anywhere with docks, stairs, ramps and bridges, remain our focus, serving residential, commercial, camping and conservation interests.

Manufacturing in Maine for the boat-dock and trail-bridge markets, you can see decades of experience and quality craftsmanship revealed in our own brands of aluminum docks, wood docks and DIY hardware. Along with our own products, we selectively host quality lines by other domestic manufacturers such as Molded Plastic Docks (MPD), the Guardian Bumper and the Drag-on Float.

Our reach, thanks to our dock system consultants – ready to assist with a virtual product tour, enables you to shop from home. In southern Maine and along the New Hampshire border we offer on-site waterfront surveying, consultation with design, and contractor installation services. Beyond our community, we assist customers and or their contractors with planning and installation of our dock, stair or bridge systems.

Our store, in beautiful downtown Naples, Maine is our factory showroom and DIY parts center, hosting a hands-on experience with our display models and our educational approach to project planning, enabling our valued customers to make informed decisions. Dock system orders and DIY parts can be picked up at our store and most DIY on-line orders ship from our store. Our docks are made in the USA.

Our people make up a talented team that is dedicated to customer satisfaction. Since the company’s beginning, it has promoted core values among its people that result in a win for the team and for you, our customer.

Our community affects us while we affect our community. Since we want good to come out of our community, we must recognize that good must go into it. Knowing this truth promotes giving of ones self and resources, one of the essential core values at Great Northern Docks.

Great Northern Docks has always been about creativity.

After brothers Sam and Seth Merriam finished the book “Building Your Own Dock” they began illustrating these fun maps of the lakes and ponds around Great Northern Docks to support local charities.
