Great Northern Docks

Great craftsmen making great products for great people since 1979

Great Northern Docks in Maine specializes in the highest quality custom boat docks designed for the harsh conditions of the New England Waterfront.

We have a complete line of turn-key solutions for the do-it-yourself market.

We also stock standard pre-built aluminum dock sections for the weekend warrior who wants it all ready to install as a weekend project.

In our showroom, and on this website, we also carry a large variety of boat dock supplies and accessories.


One of the greatest advantages of our stationary dock systems is the ability to drive pipe legs into the ground for a solid stable platform. Great Northern Docks cuts pipe legs from affordable galvanized pipe. Aluminum pipe is also available.

These platforms are often stable enough to eliminate the need for a boat lift. Consult one of our dock professionals before making a decision on securing your boat.


We build both floating boat stationary boat docks. We will look at your waterfront conditions and your intended use to help you determine whether you should have a floating dock or a stationary dock.

A floating boat dock self adjusts for changing water depths, while a stationary boat dock is more stable in shallow water.

Stationary docks are lighter to handle than floating ones, while floating ones may install faster.


We have a rugged line of galvanized and/or marine grade aluminum dock hardware. It’s suitable for small to medium size lakes, rivers and even some of the largest lakes, such as Moosehead Lake, Sebago Lake and Lake Winnipesaukee.


We design our docks for seasonal installation and most authorities recognize them as temporary docks. However, our docks are also suitable for permanent boat docks where ice is not present.

Specific requirements may vary, so please check with your local Code Enforcement Officer for regulations in your municipality.

Coastal applications may also require permission from coastal protection agencies and possibly the Army Corps of Engineers.

Here in the State of Maine, most lake docks are restricted to temporary dock permits. This is controlled by local code enforcement officers.


For those who like to do-it-yourself, we have wooden dock plans available in our literature and on this website. Our boat dock plans make it easy to build an affordable and reliable dock system sized to work with our quality dock hardware.

Choose a dock plan from our standard sizes and you are building from a design that has been time tested for decades of use.

The branding on our dock represents a level of quality that is widely recognized.


If you want a dock built and installed for you, followed by removal in the fall, we can arrange service for all of your dock needs.

Depending on your location, our field expert can visit your waterfront for a survey to help you design a dock system specific to your needs.

Once you purchase your dock we will set you up with a dock installation contractor who can provide annual installations and removals for years to come. Many of our full-service dealers also offer these services through their installation contractors.


We manufacture, distribute, and retail a line of aluminum boat docks.

Our aluminum docks are built from 6000 series marine grade aluminum. We use custom aluminum extrusions in our dock construction, designed by our engineers for ease of dock installation, and simple additions of dock accessories, like bumpers, benches, mooring whips, and dock wheels.

We build two grades of aluminum docks: Dura-Lite and Feather-Lite. Both models designed for easy setup, simple installation and removal.

Looking for an easy dock to install? Look at our Feather-Lite 4×10 aluminum boat dock sections with a 78lb frame weight. They are rugged, yet easy to handle.

The 5″ tall frame is stronger than most comparably priced products. The use of standard pipe for legs will save you money over competing square leg docks. The use of pipe will also allow you to drive the legs into the ground. This increases the stability of your boat dock and provide a more secure tie-up.

Our Dura-LITE dock sections are even stronger with a 6″ tall tubular frame and they feature removable deck panels and multiple sizes. The Dura-Lite dock is also designed for ease of adding accessories like dock cleats, or a mooring whip.

Dura-LITE aluminum floating docks are available in multiple sizes. We manufacture standard 8×8, 8×10, 6×10, 6×12, 4×10, 4×12 and 4×16 sizes. We also have rugged aluminum ramps in sizes of 4×12, 4×16 and 6×12. Longer aluminum ramps are available when required.


Enhance your swimming area with a swim raft made from our Dura-LITE aluminum line. Durable polyethylene rafts are also available here. Sizes are 8’x8′ or 8’x10′. Our polyethylene rafts are expandable to much larger sizes.


We build our own aluminum docks that roll on large wheels in and out of the water. If you have a gradual approach, a sandy or gravel bottom, and a place to store a long dock, this option will make install, removal, and adjustment much easier.

Roller Docks have several advantages, so we recommend visiting our showroom to learn if a roller dock is best for your application. See more details on the Roller Dock section of this website.


Great Northern Docks is the number one boat dock supply store in Northern New England. We have more dock planning expertise than any other dock sales company in Maine.

Because we take the product from design through manufacturing, all the way to installation, we are vertically integrated. This has enabled us to constantly improve our products and services over the past decades.

When choosing a dock provider, we encourage you to consider the quality of the product, the reputation of the service company, the stability of the company backing the warrantee, and the level of professionalism of the sales staff.

Where price is concerned, we are very competitive and we carry a wide enough product range to accommodate all budgets. As for our reputation, if you live in Southern Maine, we suggest you talk to a neighbor who has one of our docks.

When it comes to stability, we’ve been building docks since 1979, and are a strong, second generation family owned business. When it comes to professionalism, our sales staff is the most knowledgeable in the application of residential docks and boat moorings in the Lakes Region Area of Southern Maine.

Our engineering department has experience in the construction of large-scale commercial systems. We take a thoughtful, engineered approach to every dock system we design. We take accurate water depth measurements and survey bottom conditions to ensure your system will go in right.
