Summary
American Muscle Docks outlines ADA compliance for floating docks, including gangway slopes, clear widths, and slip access. The company designs structural systems and hardware to support federal accessibility standards for public marinas.
Accessible Docks Are Not Optional. They Are the Law.
The Americans with Disabilities Act (ADA) is a federal civil rights law that prohibits discrimination against people with disabilities in places of public accommodation. This includes marinas, recreational boating facilities, and public or commercial floating docks.
Floating docks are treated differently under the ADA because they move with changing water levels. The ADA Accessibility Guidelines include a dedicated section for recreational boating facilities that covers docks, gangways, slips, and accessible routes.
Compliance is not about one ramp. It is about the entire system working together.
Accessible Routes to Floating Docks
Every ADA-compliant floating dock must include at least one accessible route connecting land-based access points, such as parking or walkways, to the floating dock and slip areas.
Minimum requirements include:
- A clear width of at least 36 inches
- Firm, stable, and slip-resistant surfaces
- A maximum slope of 1:12 in most conditions
- Proper treatment of changes in elevation
These routes often include gangways that must function safely as water levels rise and fall.
Gangways and Floating Dock Connections
Gangways are the most misunderstood part of ADA dock compliance.
Because floating docks move, the ADA provides specific exceptions that recognize real-world waterfront conditions.
Key gangway provisions include:
- A standard maximum slope of 1:12
- Gangways are not required to exceed 80 feet to meet the slope
- Facilities with fewer than 25 slips may exceed a 1:12 slope if the gangway is at least 30 feet long
- No maximum vertical rise is required for floating dock gangways
These exceptions apply only to gangways. Other accessible routes must still meet standard ADA slope rules.

Clear Width and Slip Access on Dock Platforms
Accessible dock platforms must allow wheelchair users and mobility device users to move safely and comfortably.
Requirements include:
- A minimum clear pier width of 60 inches at accessible slips
- Continuous clear space along slip edges
- Limited exceptions allowing short 36-inch sections when properly configured
- Edge protection to prevent wheelchairs from rolling into the water
If a user cannot safely approach and use a slip, the dock does not meet ADA intent.
Required Number of Accessible Boat Slips
The ADA requires a minimum number of accessible slips based on the total number of slips.
Examples include:
- 1 to 25 slips require 1 accessible slip
- 26 to 50 slips require 2 accessible slips
- 51 to 100 slips require 3 accessible slips
Larger marinas continue to scale upward. Accessible slips must represent the types of slips offered at the facility.
Transition Plates Between Dock Sections
Changes in elevation along accessible routes are tightly regulated.
ADA limits include:
- Changes over 1/4 inch must be beveled
- Changes over 1/2 inch require a ramp solution
- Gaps must not trap wheels or mobility devices
Many standard floating dock hinge systems exceed these limits. ADA compliant docks often require engineered transition plates to maintain smooth movement between sections.
Dock Decking and Surface Requirements
ADA-compliant dock surfaces must be firm, stable, and slip-resistant when wet.
Common issues include:
- Slick composite or plastic decking when wet
- Metal grating with excessive openings
- Excessive flex or movement
Low-maintenance materials are not automatically ADA-compliant. Surface performance matters more than marketing claims.
Accessible Hardware and Controls
Any operable part along an accessible route must be usable with one hand, without tight grasping, pinching, or twisting.
This applies to:
- Gates and latches
- Power pedestals
- Access controls
Operable parts must be mounted between 15 and 48 inches above the dock surface.
Signage and Wayfinding
Accessible routes and slips must be clearly identified.
Requirements include:
- International Symbol of Accessibility
- Durable and legible signage
- Placement that does not obstruct access
Relying on local knowledge or informal layouts does not meet ADA standards.
The Real Reason Docks Fail ADA Inspections
Most ADA violations are not caused by major structural failures. They happen because of missed details.
Common problem areas include:
- Inadequate edge protection
- Poor transition detailing
- Slippery decking
- Incorrect hardware placement
- Insufficient clear space
If these elements are ignored, a dock can fail ADA review even if the gangway appears compliant.
How American Muscle Docks Helps
American Muscle Docks designs and fabricates floating dock systems with a working understanding of the ADA Accessibility Guidelines for recreational boating facilities.
We do not sell one-size-fits-all compliance claims. We design docks that can support ADA-compliant solutions when properly planned and installed.
Our role includes:
- Designing structurally sound dock systems capable of meeting ADA requirements
- Integrating ADA considerations into dock layout, gangways, transitions, and hardware placement
- Identifying ADA risk areas early to avoid costly retrofits
- Coordinating with owners, engineers, and inspectors during the design phase
ADA compliance is achieved through planning and execution, not assumptions.
Important ADA Compliance Disclaimer
The information provided is for general educational purposes only and is based on publicly available ADA guidelines related to recreational boating facilities.
ADA compliance is site-specific and may be affected by water-level fluctuations, shoreline conditions, local codes, environmental regulations, and installation details.
American Muscle Docks does not provide legal advice and does not guarantee ADA compliance unless explicitly stated in a written contract that defines the scope and applicable standards.
Final determinations regarding ADA compliance rest with:
- The project owner
- The design professional of record
- The Authority Having Jurisdiction
Owners are encouraged to consult qualified ADA consultants, engineers, architects, or local officials to confirm compliance for their specific facility.
