Considerations when buying a dock:
Everything You Need to Know Before Building a Dock on an Inland Lake, River, Canal, Harbor, or Protected Waterway
Building a dock is one of the best upgrades you can make to a waterfront property. It improves access, increases property value, supports boating, fishing, and swimming, and creates a beautiful gathering space.
But choosing the right type of dock for your waterway is critical — and not all docks work well in all environments.
This guide breaks down everything you need to know before you build.
1. Understand Your Waterway
Your dock must be matched to the water conditions. Consider:
Water Depth
- Shallow areas may require long walkways or pipe docks.
- Deep water often suits floating or platform docks.
Bottom Type
- Sand
- Silt
- Mud
- Clay
- Rocky conditions
Each impacts anchoring and material choice.
Water Movement
- Rivers & canals have current.
- Harbors may have boat-wake action.
- Inland lakes can have seasonal rise/fall.
Shelter Level
- Protected waters allow more dock styles.
- Exposed areas (even in bays) may need stronger anchoring.
Understanding your shoreline ensures the dock lasts decades — not seasons.
2. Choose the Right Dock Type
⭐ Stationary (Fixed) Docks
Best for:
- Stable water levels
- Firm bottom (sand, gravel, clay)
- Harbors, channels, canals
- Long-term durability
Pros:
- Extremely sturdy
- Great for entertaining, fishing, relaxing
- Long lifespan
Cons:
- Not ideal for dramatic water-level fluctuations
⭐ Floating Docks
Best for:
- Fluctuating water levels
- Soft or muddy bottoms
- Rivers & reservoirs
- Deep water
Pros:
- Automatically adjusts to water height
- Stable even in deep water
- Easy to reconfigure
- Can be modular / easily reconfigured or moved.
- Many accessory options
- Move or reconfigure with no welding or fabricating
Cons:
- Can have more movement, especially in boat-wake zones
⭐ Combination Docks
Fixed walkway + floating platform.
Best for:
- Mixed-depth shorelines
- Properties with variable water levels
3. Dock Materials — Pros & Cons
⭐ Pressure-Treated Wood
Pros:
- Natural appearance
- Cost-effective
- Traditional look
Cons:
- Requires maintenance
- Can splinter or discolor
- Shorter life span
⭐ Composite Decking
Pros:
- Low maintenance
- Long-lasting
- Slip-resistant
- Great for entertainment areas
- Higher end look and feel
- Many color options
Cons:
⭐ Aluminum Frames
Pros:
- Lightweight and strong
- Corrosion-resistant
- Ideal for floating or options for stationary docks
- Comes with several decking options and color options
Cons:
⭐ HDPE / Modular Plastic Docks
Pros:
- Ultra low-maintenance
- Resistant to moisture & rot
- Easy to install/remove seasonally
Cons:
4. Anchoring System Selection
Anchoring is the backbone of every well-built dock. Options include:
- Piling posts
- Pipe supports
- Cable systems
- Auger anchors
- Deadweight anchors
- Hybrid systems
- Stiff arms
The right anchoring depends on:
- Depth
- Current
- Bottom composition
- Wake exposure
A dock is only as strong as the way it’s secured.
5. Think About Your Primary Dock Activities
Your ideal design depends on how you’ll use the dock:
Boating
- Space for boarding
- Room for lift systems
- Cleats, bumpers & tie-ups
Fishing
- Wide platform areas
- Comfortable access points
- Rod holders or railing options
Swimming
- Ladders
- Slip-resistant decking
- Floating swim platforms
- Consider sharp edges, splinters, screws or nails
Entertaining
- Larger deck areas
- Benches or seating
- Lighting & railings
Your dock should match your lifestyle.
6. Boat Lift Considerations
If you plan to add a lift, decide early because it affects design.
Consider:
- Boat weight
- Hull style
- Water depth
- Electrical access
- Approach angle
- Boarding access
Lift systems include:
- Vertical lifts
- Cantilever lifts
- Hydraulic lifts
- PWC lifts
- Floating lifts
Proper sizing is essential.
7. Shoreline Condition & Erosion Control
Before building a dock, ensure your shoreline is stable.
Signs you may need reinforcement:
- Soil washout
- Undercutting
- Exposed roots
- Sloped or collapsing banks
Possible stabilization methods:
- Riprap
- Stone toe protection
- Revetment systems
- Bank grading
- Vegetation buffers
You should stabilize before installing a dock.
8. Permitting & Regulations (Ohio-Specific)
Depending on the waterway, you may need approvals from:
- ODNR
- County building department
- Local zoning
- Watershed authorities
- Community/HOA covenants
Permits may be required for:
- Permanent pilings
- Shoreline modification
- Lift installation
- Seawalls or riprap
Working with a contractor who handles permitting avoids headaches.
9. Seasonal Maintenance Considerations
Ohio weather affects docks dramatically.
Ask:
- Does this dock stay in or get removed seasonally?
- Should the lift come out in winter?
- What annual maintenance is needed?
- Are ice shields necessary?
A long-lasting dock is one that’s cared for properly.
10. Choosing the Right Marine Contractor
Select a builder who specializes in:
✔ Inland lakes
✔ Rivers
✔ Canals
✔ Harbors & protected inlets
Look for:
- Strong portfolio
- Local waterway experience
- Clear communication
- Licensed & insured operation
- End-to-end service (design + build + permitting)
- Sufficient equipment – chances are a newer business will not have proper equipment to do the job leading to big, expensive headaches for you in as little as 2 years.
A professionally built dock delivers safety, longevity, and peace of mind.
⭐ Final Takeaway
A boat dock is a major investment — and it should be done right.
By understanding your waterway, choosing the proper dock type, selecting the right materials, and working with an experienced contractor, you’ll get a structure that lasts for decades.
