Planning and determining dock height

Planning the height of your dock is crucial as it affects accessibility and durability. Consider the water depth, fluctuation levels, and type of boat when determining dock height.

  • Assess the average water level at your location. This involves measuring from the lake floor to the water line to get an understanding of how deep the water is where you plan to build.
  • Account for water level changes throughout the seasons. If you’re in an area with significant changes in water levels, ensure your dock can accommodate these fluctuations.
  • Calculate the draft of your boat; this measurement reflects how much of your boat will be submerged when it’s at rest. Your dock should sit nicely above this draft level to prevent damage and provide easy access.
  • Set aside room for a bottom support layer if creating a stationary dock. It will rest on lake bed and must be stable enough to handle variations in silt or sand.
  • Look at regulations regarding dock height in your local area. Communities often have rules about how high off the water docks can be built.
  • Ensure that your design allows for a gap between the top deck layer and water surface, keeping several inches clearance to protect deck materials from constant soaking.
  • Use pressure treated wood or another durable material for framing that can withstand prolonged exposure to wet conditions.
  • Incorporate allowances for anchors or weights if selecting a floating dock option. These features help keep floating docks stable despite changing water levels.
  • Optimize access points by taking into account tide patterns or currents that could impact where you place ladders or mooring points on your own dock.
  • Finalize plans with detailed illustrations or blueprints before beginning construction, making sure all measurements for height are clearly marked.

Creating footers

To create footers for your boat dock, start by marking the locations of the footers and digging holes for them. Place rebar in the holes and secure it with wire ties. Pour concrete into the holes, making sure it reaches ground level. Allow the concrete to cure before attaching the rest of the dock structure securely to the footers. This ensures a stable foundation for your dock that can withstand environmental factors and provide support for your boat.


To construct the framing of your boat dock, follow these steps:

  1. Set the layout for the basic frame using support pieces and eye hooks.
  2. Install the center support piece to ensure a secure hold.
  3. Connect the pieces parallel to create a more secure hold.
  4. Attach the last eye hook to prevent any ends from hanging.
  5. Use L braces at support intersections for added stability.

Choosing decking material

When choosing decking material for your boat dock, consider the following options:

  1. Pressure-treated wood: Offers durability and resistance against rot and insect damage, making it a cost-effective option for dock construction.
  2. Composite decking: Provides low maintenance, resistance to moisture and fading, and comes in various colors and textures for aesthetic appeal.
  3. PVC decking: Known for its lightweight nature, low maintenance requirements, and high resistance to moisture, mold, and mildew.
  4. Aluminum decking: Offers a lightweight alternative with minimal maintenance needs, resistance to weathering, and long-term durability.
  5. Tropical hardwoods: Provide natural beauty with excellent strength and decay resistance but may require more maintenance over time.
  6. Concrete or stone pavers: Boast exceptional durability and can be aesthetically pleasing but may require professional installation for optimal results.
  7. Other considerations include cost, climate suitability, local regulations, and personal preferences when selecting the best decking material for your specific dock needs.

Boat dock designs

After choosing the decking material best suited for your location and needs, it’s time to consider boat dock designs. Floating docks are versatile and can adjust to water level changes, making them ideal for deep or fluctuating waters.

Fixed docks provide stability and a permanent structure, perfect for calm waters with minimal depth change. Consider the layout options – straight, L-shape, T-shape, or U-shape – based on your waterfront activities and vessel sizes.

You may also want to incorporate features such as benches, cleats for mooring lines, and ladders into your design to enhance functionality.
