Whether you’re docking a pontoon, hosting lakeside gatherings, or creating a safe place for kids and grandkids to play, the RS7 is built to deliver season after season.
Perfect For:
Firm to soft lake bottoms

The RS7 features an oversized 6.75” ribbed side rail — the largest in its class. This means superior support for heavier loads and unbeatable durability, especially during seasonal wheel-in installations and removals that can stress weaker frames.
Thanks to modular design, exclusive 45° & 90° curve sections, and 9 premium decking options, you can build your dock to match your unique shoreline, favorite activities, or the perfect entertaining space. The InfinityTrack™ system makes adding furniture, watersport racks, or lighting completely tool-free.
With 5-Sided Dock Legs™ and 18” leg pockets, plus precision dime-welded aluminum construction, the RS7 stays firm on everything from firm to soft lake bottoms in shallow to moderate depths. Enjoy worry-free gatherings, even with kids and pets running around.
Designed for wheel-in convenience, the RS7 makes seasonal installation and removal smooth and simple — no heavy equipment or back-breaking lifts. Oversized foot pads, adjustable legs, and stackable frames mean you can roll your dock in each spring and store it neatly each winter, protecting your investment and maximizing your time on the water.

Sectional or Wheel-In — Choose the Right Seasonal Setup
The Infinity RS7 gives you the flexibility to install as a traditional sectional dock or a wheel-in dock system — so you can choose the approach that best fits your shoreline, water depth, and storage space.
When to Choose Sectional:
Perfect for uneven, rocky, or steep shorelines where rolling isn’t practical.
Ideal if you prefer lighter individual sections for easy hand-carry installation.
Sections stack neatly for compact off-season storage.
When to Choose Wheel-In:
Best for gradual or firm shorelines where rolling the dock in and out is simple.
Allows you to install and remove larger assembled sections in less time.
Oversized 6.75" rails and heavy-duty frame handle the stress of seasonal moves with ease.
With either setup, the RS7’s oversized foot pads, 18″ deep leg pockets, and dime-welded marine-grade aluminum construction keep your dock stable through every season — so you spend less time working and more time enjoying your lake.
6.75” ribbed rail sides — the strongest in its class, providing superior resistance to lateral movement and rough water.
5-Sided Dock Legs™ with 18” deep pockets lock your dock in place, even on soft or uneven lake beds.
Precision dime-welded aluminum construction means incredible durability with minimal maintenance.
“Even on our windy bay, the RS7 feels rock solid. No rattle, no sway — it’s like a patio over the water.”
— Dave H., Pelican Lake, MN
Feature | Infinity RS7 | Typical Competing Docks |
Frame Construction
| Dime-welded marine-grade aluminum for maximum strength and longevity | Riveted or spot-welded aluminum frames that can loosen over time |
Side Rail Size | Oversized 6.75″ ribbed rail — largest in its class for superior load capacity | 4–5″ rails, often flat stock with less rigidity |
Leg / Wheel Options | 5-Sided Dock Legs™ with 18″ pockets, precision adjustable; poly wheel option for smooth installs | Round legs with smaller pockets; wheel and pad options vary by bottom type |
Accessory Integration | InfinityTrack™ — tool-free accessory installation, movement, and removal | Bolt-on or drilled accessories; harder to relocate later |
Decking Options | Nine premium low-maintenance choices including Glacier™, Vertex™, and woodgrain aluminum | Three to four basic PVC, aluminum, or treated wood options |
Stability & Load Capacity | Engineered for heavier boats, larger platforms, and rougher water | Often best suited for lighter loads or calmer water conditions |
Seasonal Handling | Choose sectional or wheel-in setup; lightweight frames allow easier moving and compact stacking | Primarily wheel-in; heavier frame designs may require more effort to reposition or store |
Choose from nine premium, low-maintenance decking styles, including painted aluminum, woodgrain aluminum, flow-through poly, and ShoreMaster’s exclusive Vertex™. Each style is designed to complement your shoreline aesthetic while delivering traction, durability, and easy ownership.
Our tool-free InfinityTrack system makes it easier than ever to add furniture, steps, ladders, bumpers, cleats, lights, fishing rod holders, and more. No drilling. No hassle. Just clamp and go.
ShoreMaster’s exclusive 45° and 90° curved sections add smooth transitions and standout gathering spaces. The RS7 can use RS4 curves for added design options — just note the RS4’s 4″ rail creates a slight height difference from the RS7’s 6.75″ rail.
What makes the RS7 stronger than other docks?
The oversized 6.75” ribbed rail side is the largest in its class, meaning greater strength for mooring heavy boats and standing up to waves, with less flex over long spans.
Is it easy to install and remove?
Absolutely. Choose a wheel-in setup for fast seasonal transitions or sectional if you prefer a more permanent arrangement. Lightweight marine-grade aluminum and poly wheels make it simple for two people.
Can I reconfigure the dock layout later?
Yes. The modular Infinity RS7 system can be reshaped with new sections, corners, or accessories whenever your needs or shoreline change.
How does it handle different water depths or bottoms?
With 5-sided adjustable legs and 18” leg pockets, it handles everything from firm to soft bottoms in shallow to moderate water depths.
