The Dock System That Evolves With Your Life

Whether you’re crafting an intimate slip off your cottage for quiet morning coffee, a playful swim platform for weekend cannonballs, or a winding path that lets you cast where the big ones hide, the Infinity RS4 was designed for life by the water.

Perfect for:

  • Moderate to shallow depths (3-7 ft), stable to lightly fluctuating water levels

  • Families and cottagers who want to start small and expand easily over time

  • Gentle to moderate wave environments where a stable, elegant dock matters

  • Owners who value lightweight sections for seasonal install & compact off-season storage

Seamlessly adjust as your needs change—dock furniture one year, paddleboard racks the next, all without drilling or hiring a contractor.

Storage & Seasonal Removal

Lightweight Sections. Effortless Off-Season Storage.

The Infinity RS4 sectional dock system is designed for smooth seasonal transitions. Each lightweight dock section can be removed without heavy equipment, and our drop-in decking panels lift out individually for easy handling. Frames are stackable, so your dock takes up minimal space along the shoreline or in storage during the winter months.

Why It Matters for Sectional Dock Owners:

  • Lightweight Handling – Marine-grade aluminum frames keep each section easy to move by hand.

  • Quick Breakdown – QuickConnect™ assembly means fewer bolts and faster disassembly.

  • Compact Storage – Stackable sectional dock frames and decking store neatly in limited space.

  • Year-Round Protection – Keep your dock out of the ice and snow to extend its lifespan.

Whether you’re pulling out a few curved sections or the entire dock system, the RS4 makes seasonal removal and storage faster and simpler — so you can spend more time enjoying the water and less time wrestling with heavy, awkward parts.

FAQs for Infinity RS4 Docks:

Is the RS4 stable enough for larger gatherings or furniture?

Yes — the 4" welded frame and oversized foot pads keep the dock extremely secure, even with lounge furniture or groups gathered on wide platforms.

Can I mix the RS4 with floating or wheel-in sections?

Absolutely. Many homeowners start with an RS4 layout and later add a floating FTS9 off the end for deeper water, or wheel-in modules for easier installation on certain shores.

What’s the expected install time?

Two people can often assemble a basic 40’ RS4 dock with accessories in a few hours thanks to QuickConnect and drop-in decking. No heavy machinery needed.

How does it perform long-term?

UV-resistant decking, corrosion-proof marine aluminum, and stainless hardware mean minimal upkeep. Many RS4 docks installed over a decade ago still look nearly new.
