How to Choose the Right Dock for Your Lakefront Property

Unsure what type of dock best fits your needs?

Choosing the right boat dock isn’t just about looks — it’s about function, durability, and long-term value.

Factors like water depth, lake bottom conditions, and seasonal water level changes all play a role. For many inland lakes, a stationary aluminum sectional dock offers the best combination of strength, stability, and ease of use.

A well-chosen dock can provide decades of reliable service and countless memories on the water.

Understanding the Most Common Types of Boat Docks

Are you finally ready to install a boat dock?

Not all boat docks are created equal. The right dock for your property depends on your shoreline, water depth, and how you plan to use it.

Stationary docks are a favorite on inland lakes thanks to their stability and long-term durability. Floating docks offer flexibility in deeper water or where water levels fluctuate. Pipe docks can be budget-friendly but often require more maintenance over time. Sectional docks give property owners the ability to customize and expand their layout as needs change.

Understanding these differences makes it much easier to choose a dock that will serve you well for years to come.

Quality Still Comes First

2026 is Alumi-Span’s 70th year in business! 

One thing that makes us incredibly proud? You can still find 50- and 60-year-old Alumi-Span dock sections out in service today. They’ve weathered countless seasons and are often enjoyed by second and third generations of the same families.

Through all the years and all the changes, our values haven’t budged:

• Build things the right way
• Never cut corners
• Keep improving
• Offer honest, lasting value
• And always — always — make it in Michigan

Even today, the F-stringer style developed back in 1961 remains the most practical design for most inland docks. And Alumi-Span continues to lead the way in engineering and craftsmanship.

Looking Ahead

As we celebrate this anniversary, we’re filled with gratitude for the families who have trusted our docks, the marinas who have partnered with us, and the generations of Berlin and Hoover family members who poured their energy into making Alumi-Span what it is today.

Where the Alumi-Span Story Begins

2026 marks Alumi-Span’s 70-year anniversary!

Our story starts in 1956 inside Metalloy Foundry, run by mechanical engineer and boating enthusiast Dick Berlin. Back then, docks were heavy, rusty, and made of steel or iron. Dick saw a better way. He created an all-aluminum dock system — lighter, cleaner, and stronger than anything on the market. In fact, some of those very first docks are still out on the water today.

The Breakthrough That Changed Everything

Just a few years later, in 1961, Dick introduced what would become a defining moment for the dock industry: the F-stringer aluminum dock section. By combining F-shaped side beams with interlocking aluminum boards, he created a dock that wasn’t just lighter — it was smarter, safer, and more affordable.

People took notice:

• Alcoa recognized it as one of the best new aluminum products of the year
• It appeared in over 20 industry publications
• And soon, over 200 marinas across the northern states were carrying it

Competitors tried to copy the idea, but the original Alumi-Span system set the bar.

Intro to Uprights

When you build a boat dock, how do you use uprights?

Uprights, or dock posts, provide vertical stability and anchor the dock to the lakebed. Their functions include:

1. Height Adjustment. Uprights allow docks to be leveled according to water depth and seasonal changes. Docks with adjustable legs simplify installation and removal.
2. Foundation Anchoring. Depending on the lakebed conditions, uprights may use bottom plates, augers, or other stabilizing bases to remain secure. Alumi-Span’s permanent augers and Big Foot systems ensure stability even in soft or mucky lakebeds.
3. Load-Bearing. Uprights support the entire dock, including the dock platform itself, accessories, and any weight applied during use.

Intro to Crossarms

When you build a boat dock, how do you use crossarms?

Crossarms serve as horizontal support beams that span between upright dock posts. They are essential for:

1. Distributing Weight Evenly. Crossarms connect the uprights and help distribute the dock's weight. This ensures stability, especially under heavy weight.
2. Structural Integrity. By linking the uprights, crossarms reduce lateral (side-to-side) movement caused by water currents or wind.
3. Customization. Crossarms make it easier to build custom docks, allowing configurations like straight piers, "L"-shaped docks, or even platforms. For example, Alumi-Span offers crossarms in various sizes to match different dock designs and applications.

Party Platforms and Fishing Features

What’s your favorite thing to do on the lake?

Your dock doesn’t have to just be for boating. If you love to host company or enjoy the solitude of fishing, your dock can be a perfect place for those activities!

Party Platforms

If you love entertaining family and friends on the water, a party platform is a must-have addition to your dock. Whether it's hosting summer barbecues, sunset cocktails, or lakeside gatherings, a spacious and sturdy platform offers the ideal setting for socializing. Spice up the space by including accessories like seating, grilling stations, and games. 

Fishing Features

For anglers seeking solitude and serenity, you’ll want to design a dock you can easily fish from. Incorporating a turned section at the end of the dock or along the shoreline provides plenty of space for casting lines and reeling in the day's catch. You can also consider installing fishing rod holders, cleaning stations, and storage compartments for tackle and equipment.

Assessing Your Dock Needs

Is your boat dock equipped for your favorite activities?

Before designing the perfect boat dock, you’ll want to clearly outline your needs. Consider the watercrafts you own, whether they’re boats, jet skis, or other recreational vehicles. Think about how you want to use the space—perhaps you want your dock to be a hub for social gatherings, or a peaceful fishing retreat. Understanding your needs will guide you during the design process.

For example, if you have more than one boat or watercraft, incorporating boat slips or docks along the side of your main structure can make your dock more functional and less crowded. Boat slips provide designated spaces for each vessel. By using the space efficiently, you can accommodate multiple boats and jet skis without overcrowding the dock.

Dog-Friendly Building Materials

Is your boat dock safe for your dog?

If you have four-legged family members who love the water, ensuring your dock is canine-friendly is essential for their safety and enjoyment.

Paw-Friendly Decking: Just like kids, dogs love to run down the dock and take a leap into the water. Our docks utilize premium materials to keep everyone safe, especially your furry friends.

Wood Decking: We hand-select premium lumber during the construction process to ensure the boards are smooth and free of splinters and holes, providing a comfortable surface for your dog's paws.

Vinyl/Aluminum Decking: Vinyl and aluminum decking feature built-in tread patterns that offer traction even when wet, without being harsh on your dog's paws. Say goodbye to slippery surfaces!

Faux Wood Decking: Powder-coated faux wood decking provides a maintenance-free option with added traction to ensure safety for dogs of all ages.

Quality Cast Parts: Our docks feature cast aluminum parts that are engineered for strength and durability. Say goodbye to bending, breaking, or slipping over time, even with the most enthusiastic dogs on board.

Quality Decking: We prioritize strength and durability with structural-grade aluminum, extruded vinyl, and premium lumber decking materials. No need to worry about cracks, bends, or warping, even with the weight of excited dogs running and jumping.

Quality Build: Our docks are built to last, with center beams and side stringers made from thick-walled aluminum. Each section is weight-tested to ensure quality and safety for all family members, furry or otherwise.

Avoiding Dock-on-Dock Collision

Is your dock running into your neighbor’s dock?

It’s always best to get along with your neighbors, but many lake sites are not in line with the neighboring properties, which can cause issues with docks running into each other.  

To keep everyone on their property, Alumi-Span can put an angle across the first section of your dock. In many cases, this can bring everything back in line with the dock next to yours. This can help save you from neighborly disputes, and in the worst cases, legal action. 

Cutting an angle on an aluminum dock is a little more involved than just ripping through it with a saw. Alumi-Span takes care to make sure all decking material still has adequate support after making the cut. We also make sure to cap off any sharp edges made by cutting the angle on the dock section to avoid injury. We’ve seen plenty of bad angle cut jobs, and many lack support, which can be dangerous to walk on.

Angle cuts on a dock are a great way to place your dock exactly where you want it! Get in touch with a dock installation expert in Michigan by filling out a contact form or calling (855) 523-2444. Your dock neighbors will thank you!

Cutting Your Dock on an Angle

Is your lake front on an angle?

When cutting an angle, it’s important to measure carefully. A small angle cut at the beginning of a dock could moving the end of the dock over several feet. While this is a great way to avoid running into your neighbors, you don’t want to go too far and create a problem on the other side as well. Another thing to keep in mind is that large angle cuts (over 30-45 degrees) can take up a significant portion of the first dock piece. Careful measurement is needed here as well, especially if the length of the dock needs to be in a specific location. If you live locally, Alumi-Span can help you measure the angle cut.

Things to Consider Before Building a Boat Dock

Have you been waiting for the right time to build your boat dock? There are a few things to take into consideration before you start!

Shorelines. What does the shoreline look like where you live? Grassy? A steep descent? Rocky? This will also influence the type of dock you construct.

Water Levels and Currents. Is there a lot of boat traffic and strong currents where you live? Do water levels fluctuate often? Consider the water level of your lake before you build.

Lake Bottom Sedimentation. Before you choose a dock style, consider the bottom of the water! Is it flat and sandy? Mucky? Research which dock types will suit the lake bottom best.

Laws & Ordinances. Some lakes have regulations on maximum dock length or rules about taking the docks out in winter.  Make sure to do your research and find out what is required by the lake, county, and state where you live.

Time for Maintenance. How much time do you have to perform yearly maintenance on your dock?  Are you able to spend time staining, etc. or do you need a dock that is maintenance free?

Update and Check Your Dock Equipment

Are you concerned about the safety of your boat dock?

Having the right equipment and checking it goes a long way. Here are a few tips for building and maintaining a safe dock:

Use quality materials. Testing costs a manufacturer money, so if you buy cheap materials, they’re much less likely to have been safety tested. Quality materials are more durable and will last much longer, so even if they’re more expensive up front, they’re cheaper and safer in the long run.

Install lights. You’d be surprised to learn how many accidents can happen from simply not being able to see! Keeping your boat dock well-lit during low-light hours can prevent boat crashes, slips and falls on the dock, and other risks from reduced vision.

Frequently clean and inspect dock. It’s important to routinely check on your dock to make sure there’s no major damage. Catching issues before they become a serious threat not only protects the people using your dock, and prevents costly repairs.

Quick Tips for a Safe Dock

Have you ever had a dock mishap?

If you own a boat, you know better than anyone how unpredictable the water and weather can be. Thankfully, there are plenty of things you can do to ensure the safety and security of your boat dock. 

Go slow when docking. It’s easier to control your boat when going slow. Sharp turns are easier with less water flowing past the rudders. Cruising up to your dock gives you less control, making you more likely to hit it. Hitting your dock with your boat can cause damage to both, and the damage gets worse the faster you go.

Use boat dock bumpers. Boat dock bumpers protect the posts and edges of your dock, so if you do happen to hit it, there will be less damage. Bumpers absorb shock, which protects your dock and boat. Shock absorption also helps protect your passengers.

How to Extend the Life of Your Aluminum Boat Dock

Have you been considering aluminum boat dock sections but are still confused about your options?

As you might guess by looking at our company name, we love anodized aluminum! We choose this material for our dock sections because of its permanent layer of protective material that rivals any paint or powder-coated material. 

Anodized aluminum sections are better than other materials because:

1. They’re natural – Aluminum oxide is a naturally-occurring protective layer on the outside of aluminum. The process of anodizing thickens the layers and is sealed for unmatched protection.
2. They keep cool – Anodized aluminum, contrary to popular belief, is one of the coolest dock materials to the touch. No more burning your feet on the dock on a sunny day!
3. They’re scratch-resistant – Since the anodizing process produces a hard, protective layer on aluminum, you don’t need to worry about scratches, chips, or fading. Many paints or powder coatings would need upkeep to keep them looking new, but anodized aluminum is made to last a lifetime. Anodized aluminum dock sections are also the easiest to clean!
4. They’re eco-friendly – Because you’re avoiding using paint or power coatings, the finish is naturally occurring and is not harmful to people or the environment.

Anodized Aluminum Dock Sections: Nothing’s Lighter, Nothing’s Cooler, Nothing’s Stronger

Alumi-Span originated the all-aluminum boat dock in 1956. Don't be fooled by cheaper "non-anodized" units! Unlike some competitive units, our docks are made with a strong alloy and our acid-etched anodizing process will not turn black over time. Our dock boards interlock together and then are fastened with stainless fasteners. Tough adhesive is added to eliminate squeaks and rattles.

We manufacture our products using quality methods and materials, and that’s why many Alumi-Span aluminum boat docks are still in use after more than 50 years!

How to Extend You Boat Dock's Longevity

Are you noticing signs of wear and tear on your existing boat dock?

Owning a lake-front property can be a lot of work, and you need to maintain your aluminum boat dock just like you take care of your home and car.

Here are the top three things you need to do as a boat dock owner:

1. Get a pressure washer and learn how to use it: Regular, thorough cleaning can extend the longevity of your boat dock. Before you use a pressure washer, make sure you know how to use it the right way. Never hold the washer any closer than one inch away from the dock deck!
2. If you choose a wooden dock, you can use stain: Your boat dock needs to withstand the elements, especially here in the Midwest. Strong storms mean that your dock takes a beating, and if you have a wooden dock, you need it to last. A good oil-based stain can increase the lifetime of a wood dock.  If you have doubts about the longevity of your material, consider aluminum dock sections.
3. Use rub rails, bumpers, and boat dock fenders: Few things can shorten the life of your dock faster than a boat at ramming speed! Always practice safe boating, and make sure your dock is prepared with dock bumpers or rubber rails.

Aluminum Boat Dock Q&A

A few hours work in the spring will give you a whole long summer and fall of no-worry recreation on the water. With a little attention, your aluminum boat dock will outlast your boat.

Before you purchase a boat dock, you probably have a few questions. Here are the most common questions we get from customers:

Q: Do Aluminum docks get hot?

A: We anodize the dock sections and stringers. Anodized Aluminum is the coolest dock we sell. Mill finished aluminum docks offered by other dock companies will turn dark and get very hot. Alumi-Span does not offer mill finished aluminum on our dock sections.

Q: Can I rebuild my old aluminum framed dock sections?

A: You can rebuild your old aluminum dock sections. We sell treated pine and stained cedar panels to replace worn out wood dock sections. Our unique interlocking aluminum board design also allows you to replace old wooden sections with cool anodized aluminum decking.

Q: Can I order your products online?

A: Everything we have on the website is available for purchase. All dock parts, poles, and accessories under 8 feet can be shipped UPS and can be purchased in our online store. Dock sections cannot be purchased online, so please call us directly to get pricing on sections. If you are trying to purchase a complete dock system, call us directly for a quote.

Start off Summer Right with an Aluminum Boat Dock

It’s finally spring! Are you already dreaming about being out on the water in the summer breezes?

What’s better than being out on the lake with friends and family?

Do you need a boat dock that can provide years of fun and function for your family?

Aluminum boat docks are very low maintenance. Even though they’ll rarely need your attention, the sturdiest docks still require a lot of work to stand up to intense storms, heat, and high winds here in the Midwest. Protect your investment with regular inspections and maintenance!

Here’s what we recommend:

• If you leave your dock in year-round, you should perform a maintenance check in the spring before you tie up a boat or host a fishing party. Look for obvious signs of damage and corrosion before you attempt to use your dock recreationally.
• Lake levels (especially on the Great Lakes) can fluctuate several inches year to year. Water levels change based on rain patterns or land use near your lake. You never want waves to come over the top of your dock, so evaluate the platform height from the water and modify leg heights as needed.

Get Your Dock Ready for Summer

With summer on the way, making sure your boat dock is in peak condition is important. Nobody wants to spend the summer fixing their dock when they could be enjoying it instead!

All docks should be inspected for wear and tear before the warm season. If you have a floating dock, be extra vigilant when checking on its condition—floating docks are constantly wrestling with the water, which makes wear and tear more likely.

Aluminum boat docks are less likely to sustain heavy damage from winter weather than wooden docks and are therefore less likely to need summer maintenance. To learn more about building an aluminum boat dock, click here.
