From Destin’s welcoming greeting when we entered the store, through the dock design process, delivery and installation by Tino to the final product… the entire experience was professional but also stress-free and fun. Best of all, we got the dock of our dreams.

...LOVE THE PRODUCT, super high quality! Shipping to Alabama was great! Love my "Great Northern Dock" stairs down here in the south!

I worked with Gretta ordering the dock stairs descending into the water. Since I could not see the product, I was a little nervous ordering on my own. Gretta helped answer all my questions, and helped me figure out the best system for my situation! I don’t think I would have purchased had she not been such a great help. LOVE THE PRODUCT, super high quality! Shipping to Alabama was great! Love my “Great Northern Dock” stairs down here in the south!

My dock business has been exclusively with Great Northern for years and they will always be the only company I will work with. From start to finish you will never be disappointed investing in a Great Northern dock system.

I purchased a new dock this season from Great Northern Docks and was extremely happy with the quality and service. From the initial site review, where the team came out and created options on paper, to the prompt delivery, everything went smoothly. When my installers were short some pipe, I called and GND quickly cut a 20’ pipe into two pieces and had it ready to go within the hour for no extra charge. They also gave me a refund for a few extra pieces that I had left over after installation.The dock itself is great looking, well constructed, and very functional for fun summer days on the lake; whether boating or just relaxing on the dock. Thank you GND!

Lindsay and the team at Great Northern Docks provided excellent support and guidance in the entire process of selecting the appropriate dock that meets our needs and budget. Assembly was straightforward and the quality of the material as well as the craftsmanship was excellent. My wife and I are looking forward to adding additional accessories next year.

Swing-Up Aluminum Swim Ladders

Vertical or 20º Slanted marine grade aluminum ladders for docks and swim floats

Our Swim Dock Ladders are marine grade aluminum  and swing up on the deck for convenience of storage when not in use. Both swim ladders have a non-skid texture that is foot friendly. The 20º Swim Ladder is a favorite because it takes no upper body strength to climb and has a wider ladder step making it a bit more foot friendly than our vertical swim ladder. The Vertical Swim Ladder is quality, with appealing value.

Both dock swim ladders use the same handles but the distance between each is slightly different when mounting them to your dock, boat or swim raft. We make ladders specific to our docks for ease of installation. The Dura-LITE™ swim ladder handles snap on to our Dura-LITE™ Aluminum extrusion so there is no need to drill mounting holes. The MPD handles mount to the MPDs (Molded Plastic Docks) pre-molded bolt locations. The more common handles for wood docks, swim rafts, etc. are made to bolt to the deck surface and through the side of the frame for the proper strength required.

When choosing a ladder for your existing dock that’s not a Dura-LITE™ or an MPD, you will be best served by our standard handles for wood docks. These handles work with your choice of 20º or vertical ladder. When ordering a ladder for your swim area, look below to help choose the Swim Dock Ladder that’s right for you.

20º Dock Ladder

  • Dock Ladder with 20º slant makes it easy to climb
  • Non-skid, foot friendly tread for traction when wet
  • Swings up for easy storage
  • Mounts to wood docks, Great Northern Docks aluminum sections, and Great Northern Docks MPDs.

Vertical Dock Ladder

  • Excellent value, longer depth for docks that are high above water
  • Non-skid, foot friendly tread for traction when wet
  • Swings up for easy storage
  • Mounts to wood docks, Great Northern Docks aluminum sections, and Great Northern Docks MPDs.
