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.

Wy Experience Matters in Dock Design

When it comes to building a dock, experience makes all the difference. A seasoned designer understands local water conditions, weather patterns, and material performance—ensuring your dock stands strong for years to come. They’ll know how to prevent common issues and tailor each design to fit your shoreline’s unique needs.

So, when you’re hiring a dock designer, ask these questions about their experience: 

1. How long have they been designing docks? 
2. What types of projects have they completed, and can they share examples of their work?
