Start with your shoreline: pick what sounds like your situation and we’ll point you to the right system. These are the most common waterfronts we build for.
Stationary docks have pipe legs that are driven into the lake bottom. This is the most rigid option for lakes that don’t swing in depth.
EXPLORE STATIONARY DOCKS
Floating docks rise and fall with changing water levels through the season, and are perfect for when pipe legs can’t be installed.
EXPLORE FLOATING DOCKS
Roller docks are great for sandy, gradually sloped shorelines where your dock can be rolled in and out with less hassle each season.
EXPLORE ROLLER DOCKS
Hand-built in Naples since 1979. A dock designed to grow older with your waterfront using durable materials and replaceable components.

Great Northern Docks started in the 1970s, when Fremont Merriam, a structural designer, couldn’t find a dock that would hold up on his own Maine lake. So he designed one himself, strong enough to take the punishment of a big lake, but light enough to pull out every fall so the winter ice couldn’t tear it apart.
Other waterfront owners wanted that same dock, so Fremont turned it into a business alongside his sons. Three generations later, we still handcraft our aluminum docks and stairs in Naples, and we still make the original wood dock hardware that started it all.

How It Works
No pressure, no commitment. Just tell us what you need, and we’ll let you know how we’d get it done.
A dock specialist reviews your project and calls to discuss options, answer questions, and refine the details.
Get a detailed quote with product recommendations, pricing, and installation options, usually within one business day.
Because every dock is customized to your shoreline and layout, the final price depends on more than just the standard dock sections. Bracing, connectors, support components, anchoring, accessories, and any project-specific modifications all affect the total, so we provide a custom quote for every project.
We actually have an article that can explain why this is important: Winter Dock Storage Tips.
Yes, we ship aluminum dock systems, stairs, and accessories nationwide. We’ve delivered to Texas, Minnesota, and everywhere in between. Installation support varies by region.
We’ll give you an honest timeline when we quote your project, since lead time depends on the season and the system you choose.
Installation time and difficulty depend on several factors, including the dock configuration, site complexity, personal experience, mechanical aptitude, and physical capability. For those planning to install the dock themselves, we often recommend observing an installer who is familiar with our products during the first installation. We can help you determine whether hiring an installer is the right choice for your project.
