WHAT IS A 4-POST BOAT LIFT?

A Stable, Proven Lift System for Open Slips

A 4-post boat lift raises your vessel vertically between four pilings using a cradle, cable, and drive system. This is one of the most widely used lift configurations for residential docks, canal homes, and marina slips because it provides stable support, straightforward operation, and strong lifting performance.

A 4-post lift is typically the right choice when your dock or slip has pilings positioned around the boat, allowing the vessel to be lifted straight up and stored safely above the waterline.

Common applications include:

  • Waterfront homes along Florida canals

  • Intracoastal waterway properties

  • Private marina slips

  • Open-water dock installations

Designed for Saltwater Environments

Built for Florida’s Coastal Conditions

Saltwater, humidity, tides, sun, and daily use put constant stress on marine equipment. Neptune 4-Post Boat Lifts are engineered for these demanding waterfront conditions with durable materials, corrosion-conscious components, and heavy-duty construction.

Built with premium marine materials

Neptune 4-post lifts use aluminum and stainless-steel construction designed for long-term performance in saltwater environments. Marine-grade 6061-T6 aluminum structural framing provides strength without the corrosion concerns of untreated steel.

Direct-drive performance options

Choose from multiple drive systems depending on your speed and performance needs:

  • Standard Direct Drive for dependable everyday lifting

  • G3 High-Speed Direct Drive for faster operation

  • G6 SuperFast Direct Drive for maximum lifting speed

Invest in a Neptune Four-Post Boat Lift today and enjoy the perfect combination of American craftsmanship, smart technology, and outstanding durability. Give your boat the protection it deserves with the most reliable lift on the market.

HIGH-SPEED DIRECT DRIVE PERFORMANCE

Faster Lifting. Smoother Operation. Fewer Maintenance Points.

Neptune offers multiple direct-drive systems designed to improve lifting speed, simplify operation, and reduce maintenance compared with belt- or chain-driven configurations.

Direct-drive systems eliminate belts and chains, helping create smoother, more efficient lifting performance. For boat owners who use their boats often, faster lift operation can make launching and storing the vessel easier every time they return to the dock.

Available drive options

Standard Direct Drive: Dependable lifting performance for everyday use.

G3 High-Speed Direct Drive: Increased lift speed for boaters who want faster operation.

G6 SuperFast Direct Drive: Neptune’s highest-performance drive option for maximum lifting speed.
