Planning custom boat docks for your waterfront property is one of the most important decisions you will make as a lake homeowner. A dock that is built right from the start will last for years, work with your shoreline, and make everyday life on the water easier. A dock that is rushed or poorly planned will cost you more in repairs and frustration down the road.
At Cumberland Marine Works LLC, we have helped property owners across Old Hickory Lake, Percy Priest Lake, the Cumberland River, and throughout Middle Tennessee build custom lake docks that fit their property and their lifestyle. Here is how to plan yours the right way.
Step 1 – Understand Your Shoreline Before You Plan
No two shorelines are the same. Before any dock construction begins, you need to know your water depth, how much your water levels fluctuate through the year, and what your shoreline looks like at different seasons.
These factors determine which dock type will work best for your property:
- Floating docks – best for waterways with fluctuating water levels like Old Hickory Lake and TVA-managed waterways. They rise and fall with the water and stay usable year-round.
- Fixed docks – best for areas with consistent water depth where you want a permanent, rigid structure.
- Hybrid dock systems – combine the stability of a fixed dock with the adaptability of a floating system. A good option when conditions call for both.
A qualified dock construction company will assess your site before recommending any dock type. Skipping this step leads to mismatched designs that underperform.
Step 2 – Define How You Will Use Your Dock
Custom boat docks should be built around how you actually use the water. Before you talk to a builder, ask yourself:
- Do you need a single boat slip or multiple slips?
- Will you want a swim platform or sitting area?
- Will you be adding a boat lift now or later?
At Cumberland Marine Works LLC, every project we take on starts with understanding your usage needs and long-term goals. We build custom lake docks for private lake homes, waterfront estates, marinas, commercial properties, and boat clubs – and each one is designed differently based on how it will be used.
Step 3 – Choose the Right Materials
Material choice affects how long your dock lasts and how much maintenance it requires. Our dock construction uses Hot Dipped Galvanized Steel frames – designed to resist corrosion and withstand rough waters better than a standard box truss dock frame.
This matters on active waterways where dock structures face constant stress throughout the year. Choosing the right materials from the start is one of the most important decisions in the dock construction process.
Step 4-Plan for a Boat Lift From the Start
One of the most common mistakes in custom boat docks planning is treating the lift as an afterthought. If you plan to add a boat lift-now or in the future – your dock structure needs to be built with that in mind from the beginning.
We design every dock with lift compatibility built in. This ensures safety, proper weight distribution, and long-term reliability. If you are still deciding on a lift, read our guide on choosing the right dock builder to understand how dock and lift planning work together.
Step 5 – Work With an Experienced Dock Construction Company
The difference between a dock that lasts and one that fails comes down to who builds it. Look for a dock construction company that:
- Visits your site before quoting
- Gives you a custom design – not a one-size-fits-all solution
- Is transparent about materials and timeline
- Has experience on the specific lake or waterway you are on
