Freshwater Boat Protection

Why UltraLift Is Right for You

The UltraLift® Series combines a broad range of lifting capacities with hydropneumatic operation and purpose-built freshwater construction—helping protect your boat while making every launch easier.

Built for Freshwater Boats

Published capacities from 5,000 to 32,000 lbs. support freshwater pontoons, tritoons, fishing boats, wake boats, cruisers and yachts.

Less Maintenance, More Boating

Hydropneumatic operation uses air and water displacement without the traditional cables and pulleys used by many mechanical lift systems.

Made in the USA

UltraLift systems are engineered and manufactured in the United States using purpose-built tanks, frame components and controls.

Dependable Waterfront Protection

A properly sized and installed lift helps keep the boat supported above the water and protected from everyday dock contact, wakes and changing waterfront conditions.

UltraLift may be a fit when: your boat is used in freshwater, your dock has a compatible floating slip and your fully loaded boat weight falls within the published UltraLift capacity range.

Every installation should be sized and configured by an authorized HydroHoist dealer for the specific boat, dock and water conditions.
The Engineering Behind the Lift

Why Hydropneumatic Design Matters

UltraLift does more than raise a boat. Its hydropneumatic system replaces traditional cable-and-pulley lifting with controlled buoyancy, purpose-built flotation tanks and a structural frame designed for freshwater installations.

Air Creates Lift. Water Controls the Cycle.

A 120V motor introduces air into the polyethylene tanks, displacing water and increasing buoyancy. Releasing air allows water to return to the tanks, lowering the lift in a controlled manner.

01

Even Hull Support

Adjustable hull-support placement helps distribute weight and support the boat in the configuration established by the dealer.

02

Fewer Moving Components

Hydropneumatic lifting avoids the traditional cables, pulleys and cradle mechanisms used by many mechanical lift systems.

03

Structural Strength

The UltraLift frame incorporates heavy-duty torsion bars, Grade-8 pivot hardware and purpose-built structural connections.

04

Repeatable Marina Operation

Push-button operation gives owners, marina staff and tenants a consistent process across compatible UltraLift installations.

Built for North American Waters

From Grand Lake, Lake Texoma, and Lake of the Ozarks to freshwater marinas across the U.S., the UltraLift thrives in tough conditions:

  • Fluctuating water levels? UltraLift rises and falls with ease.

  • Heavy weekend traffic? The structure absorbs wave energy, protecting your hull.

  • Seasonal stress? Store your boat high and dry — no algae, no dock rash.

UltraLift® hydropneumatic boat lifts represent HydroHoist’s flagship freshwater lifting technology. Designed for smooth, push-button operation and long-term durability, UltraLift® systems use proven hydropneumatic principles to lift and protect boats with minimal mechanical complexity and reduced wear.

Whether you’re a private boat owner or managing a multi-slip marina, UltraLift® hydropneumatic boat lifts deliver consistent performance across a wide range of boats, dock layouts, and water conditions.

UltraLift Quick Specs

  • UltraLift lifts support boats ranging from 5,000 lb to 32,000 lb depending on model.

  • Minimum water depth typically ranges from 4 feet to 7 feet plus boat draft.

  • UltraLift systems use high-density polyethylene flotation tanks.

  • UltraLift frames include ¼-inch torsion bars and Grade-8 pivot hardware.

  • UltraLift lifts operate using a 120V electric motor system.

  • Connect with a local dealer to confirm UltraLift sizing and installation requirements for your boat.

What Makes a Hydropneumatic Boat Lift Different

Hydropneumatic boat lifts operate using a combination of air and water displacement rather than cables, pulleys, or cradles. With the push of a button, air is introduced into the lift’s tanks, displacing water and gently raising the boat. To lower the lift, air is released and water returns to the tanks in a controlled manner.

This approach offers several advantages:

  • Smooth, even lifting that supports the hull evenly

  • Fewer moving mechanical components

  • Reduced wear and long-term maintenance

The result is a reliable lifting system that’s easy to operate and built for longevity.


Why Marinas Choose Hydropneumatic Boat Lifts

Hydropneumatic lifts are widely used in freshwater marinas because they offer:

  • Consistent performance across multiple slips

  • Simple, repeatable operation for staff and tenants

  • Reduced mechanical complexity compared to cable systems

  • Scalable solutions for expanding dock systems

UltraLift® hydropneumatic lifts allow marinas to standardize equipment, streamline training, and deliver a premium experience to boaters.

What UltraLift Owners Are Saying

From everyday convenience to decades of service, UltraLift owners trust their lifts to protect their boats and keep them ready for the water.

Proven Reliability

Six Seasons of Dependable Protection

“We love our HydroHoist boat lift. It has never let us down in six seasons of use and has kept our boat nice and secure for many years. Peace of mind is so important when choosing a lift.”

Mike H. Sequoyah Marina, Tennessee
Long-Term Durability

Still Working After Two Decades

“The 20-year-old HydroHoist lift that came with our lake home is still in use today. It is a testament to durability and function, especially in the rough-water environment of the Ozarks.”

John D. Lake of the Ozarks, Missouri
Tritoon Protection

More Confidence Between Boat Days

“It keeps our tritoon out of the water when we’re not using it, helping protect the pontoons from algae, stains and long-term water exposure. It also gives us peace of mind when storms roll through or the lake gets rough.”

Bridget N. Lake Norman, North Carolina

UltraLift® Boat Lifts FAQs

From 5,000 to 32,000 lbs, covering everything from fishing boats to luxury cruisers.

Its above-water steel design eliminates corrosion and extends lifespan far beyond traditional lifts.

With a 120V Electrolux motor: water is pumped out of the tanks to raise your boat or allowed in to lower it — all with the push of a button.

Each lift is customized. Pricing depends on capacity, dock type, and installation. Contact your dealer for a quote.

UltraLift can be configured for floating docks, and U-shaped slips.

A hydropneumatic boat lift uses air and water displacement to raise and lower a boat rather than cables or mechanical hoists. Air is added to tanks to lift the boat and released to lower it in a controlled manner, providing smooth, even support.

Hydropneumatic lifts operate by introducing compressed air into sealed tanks, which displaces water and causes the lift to rise. When lowering the boat, air is released and water returns to the tanks. This system allows for controlled, push-button operation with minimal mechanical wear.

Lift capacity depends on the total weight of your boat, including fuel, gear, and accessories. Beam width and draft also play a role. A dealer can help determine the correct UltraLift® capacity to ensure safe operation and long-term performance.

Yes. Hydropneumatic boat lifts are commonly used in freshwater marinas due to their reliability, ease of operation, and ability to scale across multiple slips. They help standardize marina infrastructure while delivering a premium experience for boaters.

Professional installation is strongly recommended. Hydropneumatic systems are site-specific, and a dealer ensures proper setup, alignment, and integration with your dock system.
