Floating Breakwater Case Study: Marina Protection at Grand Lake, Oklahoma

The Marina at Grand Point on Grand Lake, Oklahoma needed a serious wave protection solution. Like many large reservoir marinas, the facility faced relentless boat-wake activity and significant wind-driven wave fetch across open water. The result was constant chop in the slips, stress on dock hardware, and a customer experience that suffered every weekend the wind blew.

The marina's response was a custom-engineered Wavebrake floating breakwater system. Here's what the project teaches any marina dealing with similar conditions.

The Site Conditions

Grand Lake is a large reservoir in northeast Oklahoma with substantial fetch in multiple directions and high recreational boat traffic. Marinas on the lake face combined wave loading from sustained winds and from the wakes of cruisers, ski boats, and pontoon boats moving through congested waters. These conditions are tough on traditional dock structures and on customer satisfaction.

A site evaluation captured the specific wave climate, wind exposure, water depths, and bottom conditions. Those details drove the engineering, ensuring the system would be sized appropriately for the wave forces at that exact location.

The Engineered Solution

The Wavebrake system at Grand Point uses a multi-row module configuration designed specifically for the marina's wave climate. The configuration delivers strong wave attenuation while maintaining a manageable system width for the marina layout.

Anchoring was engineered for the lake's bottom conditions and the calculated wave forces. Front and rear anchor lines work together to keep the system locked in the wave while allowing it to flex with changing conditions.

What Made the Project Work

Several factors set this installation up for success. First, the system was custom-engineered, not a stock product applied to a unique site. Second, the anchoring package was designed specifically for the bottom material and wave loads at Grand Point, not over-specified or under-specified. Third, the modular design allowed the marina to install the protection without disrupting normal operations or closing the facility.

Why the Marina Chose Wavebrake

The decision came down to performance, cost, and operational compatibility. Stone breakwaters would have required barges and cranes the lake couldn't easily support, plus permitting complications and ongoing maintenance. Concrete pontoons risked lifting in storm surge and damaging the dock complex. Wavebrake offered up to 85% wave reduction, no environmental disruption, and a price point that made the project feasible.

The Bigger Lesson for Marinas

Grand Point isn't unique. Reservoir marinas, lake marinas, and protected coastal harbors across the country face similar wave problems. The lesson is that effective floating breakwater protection is now within reach for marinas of every size — and the technology has matured to the point where custom-engineered solutions can match almost any site's specific conditions.


What Competitors Won't Tell You

Most coastal protection options on the market — stone breakwaters, seawalls, concrete pontoons, and rock revetments — share a hidden problem: they reflect wave energy. When a wave hits a hard, fixed surface, it doesn't disappear. It bounces back into the water, creating a rebound wave that scours sediment, undermines neighboring properties, and eventually damages the very structure meant to provide protection.

This reflective action is why so many waterfront owners pour money into seawalls only to watch them fail within ten to fifteen years. The wall stops the first wave, but the rebound chews away the foundation underneath. Concrete floating pontoons have the same flaw, plus they tend to lift and shift in storm surge, leaving boats and docks exposed exactly when protection matters most.

Stone revetments are even more deceiving. They're sold as permanent solutions, but they require massive amounts of armor stone, heavy machinery to install, and they damage the marine environment during construction. Over time, settling and storm displacement turn them into ongoing maintenance projects.

Why Wavebrake Is the Only Real Solution

Wavebrake doesn't reflect wave energy. It absorbs it. The porous, multi-faceted module design channels each wave into internal cavities where turbulence cancels the energy out. The result is up to 85% wave reduction with no rebound damage to surrounding shorelines.

  • Custom-engineered for your specific site conditions, wave type, and water depth
  • Up to 85% wave attenuation — outperforming the 80% target of stone breakwaters
  • Floats with tide, storm surge, and water level changes — always in the wave
  • No heavy equipment, no barges, no cranes — installed with a small boat
  • Zero negative environmental impact — actually creates fish habitat
  • Built to withstand cold, heat, UV, and decades of marine conditions
  • Modular and scalable — extend, reconfigure, or relocate as conditions change
  • A fraction of the cost of stone, seawalls, or concrete pontoon systems

Wavebrake is the only floating tethered breakwater that adjusts to the variables Mother Nature throws at your shoreline. Every system is custom-designed by our engineering team based on the specific conditions at your site. There is no one-size-fits-all — there is only what works for you.
