Cumberland Marine Works offers custom steel docks at an affordable cost to fit any budget.
Our Hot Dipped Galvanized Steel Dock is designed, fabricated and available in custom designs. This dock is galvanized to resist corrosion and is designed to withstand rough waters better than a standard box truss dock frame. Trust Cumberland Marine Works to provide a durable and cost-effective steel dock solution that meets your specific needs.


Premium Boat Docks on Old Hickory Lake & Across Tennessee, Kentucky, and Alabama

At Cumberland Marine Works, we specialize in custom dock construction designed for real-world durability, long-term performance, and seamless integration with your waterfront property.

Custom Dock Design & Construction Built Around Your Property
No two shorelines are the same, and your dock shouldn’t be either. Every project we build is custom designed based on your water depth, shoreline layout, usage needs, and long-term goals. Cumberland Marine Works specializes in fully custom dock builds for:
- Private lake homes
- Waterfront estates
- Marinas and multi-slip docks
- Commercial waterfront properties
- Boat clubs and shared docks
From concept to completion, we build docks that are engineered for your environment and built to perform season after season.

Floating Docks, Fixed Docks & Hybrid Systems
Choosing the right dock type is critical for both performance and longevity. Our team designs and builds multiple dock styles to match the unique conditions of Tennessee lakes and rivers.
Floating Docks
Ideal for fluctuating water levels like Old Hickory Lake and TVA-managed waterways, floating docks provide flexibility while maintaining stability and usability year-round.
Fixed Docks
For areas with consistent water depth, fixed docks offer unmatched rigidity and a classic, permanent dock feel. We can build the perfect dock that fits your property.
Hybrid Dock Systems
In some locations, a hybrid dock design delivers the best of both worlds, combining stability with adaptability. We’ll help you determine the right solution.
