Hewitt Roll a Dock
A Hewitt Roll-A-Dock represents one of the most durable and time-tested wheel-in marine dock systems available for freshwater lakes and calm riverfront shorelines. Engineered for seamless seasonal placement and removal, this modular rolling dock eliminates the grueling physical labor of carrying heavy dock sections through deep mud and cold water. Property owners can simply wheel the entire assembly into position in spring and roll it out onto dry land before winter freeze-up. Understanding frame construction options, adjustable screw jack mechanisms, lakebed terrain compatibility, and modern composite decking selections ensures waterfront homeowners choose the optimal dock configuration for their recreational boating lifestyle.
Waterfront living offers unparalleled relaxation, but seasonal dock maintenance often presents a formidable physical challenge. In northern climates where lakes freeze over, permanent pilings risk ice-jacking damage, requiring docks to be pulled ashore every autumn. The Hewitt Roll-A-Dock was specifically engineered to solve this dilemma through heavy-duty pneumatic or poly wheels, modular truss frame construction, and built-in mechanical adjustment jacks. Rather than wading through ice-cold water dismantling individual 100-pound pipe sections, one or two people can easily push or pull an entire 40-foot to 80-foot rolling dock system onto the shoreline using a garden tractor, utility vehicle, or simple manual effort.
Engineering Fundamentals: Aluminum vs. Galvanized Steel Frames
Hewitt fabricates Roll-A-Dock systems in both structural aluminum and hot-dipped galvanized steel, catering to differing lakebed dynamics, current strengths, and owner preferences. Aluminum roll-in docks are prized for their exceptional strength-to-weight ratio, lightweight handling, and natural corrosion resistance. The aluminum truss structure utilizes heavy-gauge rectangular stringers and cross braces that flex slightly under wave action without permanent deformation. Because aluminum is significantly lighter than steel, it proves far easier to maneuver across soft lawns, gravel ramps, and sandy beaches during spring launching and fall extraction.
Conversely, Hewitt galvanized steel Roll-A-Docks provide maximum mass and ballast for open-water shorelines subjected to intense boat wakes, heavy crosswinds, and rolling swells. The extra weight of dipped structural steel keeps the dock firmly anchored against the lake bottom, preventing shifting or rocking when larger pontoon boats or wakeboarding craft moor alongside. While heavier steel requires greater towing power during seasonal transitions, its unmatched structural rigidity makes it a preferred standard on sprawling recreational lakes where lightweight docks might get tossed by afternoon whitecaps.

| Heavy-Duty Galvanized Steel | Hot-Dipped Tubular Carbon Steel | 75 - 90 lbs / ft | Rocky bottom, heavy boat wakes, drop-offs | 4 ft, 6 ft | $4,500 - $8,900 (32-48 ft) |
| Commercial Truss Aluminum | Reinforced Box Aluminum Truss | 60 - 70 lbs / ft | Marina slips, high-traffic private bays | 6 ft, 8 ft | $6,200 - $11,500 (40-60 ft) |
| L-Section Patio Extension | Matched Aluminum / Steel Frame | 50 - 80 lbs / ft | Recreational sun decks, boat lifts | 8 ft x 8 ft to 10 ft x 16 ft | $2,400 - $4,800 (Add-on) |
Decking Surface Selections and Slip-Resistant Performance
Modern Hewitt docks feature interchangeable drop-in decking panels designed to balance aesthetics, barefoot comfort, and minimal maintenance. Classic western red cedar provides a timeless rustic appearance that stays cool under direct summer sunlight, but requires periodic sealing to resist mildew and splintering. For zero-maintenance longevity, many dock owners opt for Hewitt anodized aluminum decking planks. Aluminum panels feature slip-resistant ribbed grooves and powder-coated enamel finishes that stay remarkably cool while eliminating wood rot, decay, and power-washing chores.
For windy, wave-tossed bays, open-grate composite decking such as ThruFlow represents the gold standard. Engineered with thousands of tiny perforations, ThruFlow panels allow high-energy waves, surging stormwater, and sunlight to pass directly through the dock surface without generating hydrodynamic lifting pressure that could dislodge deck sections. Furthermore, passing sunlight helps preserve sensitive aquatic vegetation and fish spawning beds beneath the dock, fulfilling strict environmental zoning standards in many protected lake jurisdictions.
Wheel Kits, Axles, and Lakebed Shoreline Adjustments
The operational secret of the Roll-A-Dock lies in its axle wheel kits and telescopic support legs. Hewitt equips these systems with heavy-duty molded polyethylene or pneumatic rubber wheels mounted on self-lubricating polymer composite or bronze bushings. These wide wheels glide over sandy bars, gravel shallows, and sunken cobblestones without sinking or binding in muddy silt. For properties with steep shoreline drop-offs, Hewitt incorporates dual-wheel assemblies that provide additional buoyancy and surface flotation during transit.
Leveling the dock across an uneven, undulating lakebed is achieved using integrated screw jack uprights. Rather than entering the water with wrenches, dock owners adjust deck heights from above the water surface using a cordless drill adapter or hand crank winch. Each telescopic leg adjusts independently, compensating for hidden boulders, slope drops, and shifting water levels throughout the boating season without disturbing the docked watercraft.
| Dock Construction Type | Annual Labor Requirement | Winter Ice Survival Strategy | Optimal Lakebed Substrate | Typical Lifespan (Years) | Relative Maintenance Effort |
|---|---|---|---|---|---|
| Hewitt Wheel-In Roll-A-Dock | 1 - 2 Hours (1-2 people with UTV) | Complete roll-out onto dry lawn bank | Gradual slope, sand, firm mud, gravel | 25 - 40 Years | Extremely Low (Periodic grease/wash) |
| Sectional Post & Pipe Dock | 6 - 12 Hours (Multiple strong adults) | Manual piece-by-piece disassembly | Deep water, steep drops, uneven rock | 15 - 25 Years | High (Frequent pin/bolt replacement) |
| Floating Pontoon Dock | 2 - 4 Hours (Detach shore ramps) | Towed to calm cove or de-icing bubbler | Deep water, extreme water fluctuations | 15 - 30 Years | Moderate (Inspect anchor chains/drums) |
| Permanent Wood Crib / Piling | None (Left in lake year-round) | High risk of ice heave / requires bubbler | Bedrock, solid compacted clay | 12 - 20 Years | High (Deck boards rot, pilings shift) |
How to Install and Level a Hewitt Roll-A-Dock for the Boating Season
Follow these step-by-step instructions to safely launch, roll, position, and level your Hewitt Roll-A-Dock at the beginning of the lake season.
Inspect Axle Pins, Tires, and Frame Hardware
Prior to rolling the dock toward the water, inspect all axle cotter pins, check pneumatic tire pressures (or examine molded poly wheels for cracks), and confirm all frame connecting bolts are torqued tight.
Attach Shoreline Tow Harness or Winch Strap
Connect a heavy-duty tow strap to the welded tow eye on the dock frame and attach it to your ATV, lawn tractor, or shoreline manual winch to guide the dock safely down the embankment.
Roll the Dock Assembly Steadily into the Lake
Slowly back or push the dock straight into the water. Allow the wheels to roll along the lake bottom until the dock reaches your designated mooring depth and orientation.
Engage Top-Side Screw Jacks to Level the Deck
Using the manufacturer-provided crank handle or cordless drill attachment, turn each top-mounted screw jack until the dock pads firmly plant on the lake bottom and the deck surface is level.
Secure Shore Ramps and Install Mooring Cleats
Attach the shore ramp connecting pins to your shoreline seawall or turf stakes, install safety bumpers along the outer dock perimeter, and fasten heavy-duty boat mooring cleats.
