Are you finally ready to install a boat dock?
Unsure what type of dock best fits your needs?
With several styles available, choosing the right dock comes down to your shoreline, water depth, usage, and long-term goals. Here’s a breakdown of the most common types of boat docks and how to decide which one fits your needs best.
Stationary (Permanent) Docks
Stationary docks are fixed in place using galvanized steel legs that auger into the lakebed. These docks are known for their stability and durability, making them a popular choice for inland lakes with limited ice flows in winter.
Best for:
- Shallow to moderate water depths
- Lakes with minimal water level fluctuation and few ice flows
- Rivers, channels, or other protected lake front
Stationary aluminum docks are especially popular because they’re lightweight, corrosion-resistant, and hold up to weather extremes.
Sectional (Removable) Docks
Sectional docks are modular systems made up of interchangeable sections. This design allows for customization and future expansion as your needs change.
Best for:
- Property owners who want flexibility
- Custom dock layouts
- Easy repairs or modifications
Aluminum sectional docks are especially valued for their strength-to-weight ratio, long service life, and ease of install/take out.
Combination Permanent & Sectional Docks (Perma-Auger Systems)
For dock owners who want the best of both worlds, combination dock systems offer a smart middle ground. These docks use sectional aluminum dock sections paired with perma-augers, providing the stability of a permanent dock while still allowing for seasonal removal.
Perma-augers screw directly into the lakebed, creating a secure, rock-solid foundation that resists shifting from waves, wind, and normal water movement. Unlike traditional driven posts, augers provide exceptional holding power while remaining removable when needed.
Best for:
- Property owners who want permanent-style stability
- Lakes where seasonal dock removal is required
- Areas with firm lake bottoms
- Dock owners who want easier installation and takedown
This hybrid approach is especially popular in regions with ice concerns. The dock sections can be removed for winter while the augers stay in place, making spring installation faster and easier. When reinstalled, the dock locks back into the same solid footprint year after year.
Combination dock systems deliver the confidence of a permanent dock with the flexibility and convenience of a sectional system — without sacrificing durability or ease of use.
How to Choose the Right Dock for Your Property
When deciding which dock is right for you, consider these key factors:
- Water depth and lake bottom conditions
- Seasonal water level changes
- Boat size and usage
- Installation and removal preferences
- Long-term durability and maintenance needs
If you’re unsure which dock system is right for your shoreline, the Alumi-Span team is always happy to help guide you through the decision-making process.
