Position On-Site Lift Systems for Boathouse Applications

Built around the structure, vessel, and project requirements.

Neptune Position On-Site Boathouse Lift Kits are designed to integrate into covered-slip and boathouse structures. Rather than treating each installation as a standard layout, Neptune evaluates the application based on the vessel, existing structure, support conditions, drive requirements, and final installation needs.

A Neptune Boathouse Lift Kit may be considered when the project involves:

  • A covered-slip or boathouse structure

  • Existing beams or structure suitable for lift integration

  • Vessel support requirements that require custom bunking or cradle configuration

  • Single-drive or double-drive lift needs

  • Project-specific installation review by a qualified marine contractor

Every Boathouse Lift Kit should be reviewed based on the structure and vessel before final selection.

Built for Covered-Slip Applications

Neptune Boathouse Lift Kits are designed to work within the conditions of a covered structure. The lift components are selected and positioned around the application so the system can support the vessel properly within the available structure.

Because every boathouse is different, structural layout, beam placement, water depth, access, vessel weight, beam, and drive configuration all affect final lift selection.

Integrated Into the Existing Structure

A Boathouse Lift Kit is different from a free-standing lift because it depends on the surrounding structure. Final fit and assembly happen during installation, so proper project review is important before selecting the system.

Neptune can provide lift components and configuration guidance, while authorized dealers and qualified marine contractors review installation requirements for the specific structure.

Key application factors may include:

  • Vessel loaded weight

  • Vessel beam and hull design

  • Existing boathouse structure

  • Beam location and support conditions

  • Drive unit placement

  • Cable and winder layout

  • Bunking requirements

  • Electrical requirements

  • Water depth and travel needs

Single Drive and Double Drive Configurations

Neptune Boathouse Lift Kits may be available in single-drive and double-drive configurations depending on capacity, vessel requirements, structure, and installation needs.

A Single Drive Side Mount configuration is commonly used for smaller-capacity applications where a compact, efficient system is appropriate. An optional center shaft may be available depending on the setup.

A Double Drive configuration supports higher capacities and provides additional lifting capability for larger recreational boats. These systems are commonly used when the boat weight, cradle size, or boathouse layout requires more lifting support.

Your Neptune dealer can help determine which configuration is right based on the boat, the structure, and the way the lift will be used.

Capacity and Specifications

Neptune Boathouse Lifts are available in multiple capacities, with single-drive and double-drive options depending on boat size and lift requirements. Final specifications vary based on structure, beam layout, travel, voltage, bunk setup, and installation conditions.

Because every boathouse structure is different, a dealer evaluation is recommended before selecting a model.

Neptune Boathouse Lift kits are designed to provide the essential components needed for a complete covered-slip lift system. Depending on the model and configuration, standard kit components may include a wired drive unit with switch wiring, a manual switch, GFCI 110V setup, a complete marine-grade aluminum bottom cradle, stainless steel hardware, carpeted wood bunks, aluminum grooved cable winders, and stainless steel cables.

Available options allow the system to be tailored to the boat and boathouse. Common upgrades may include guide pole kits, aluminum bunks, single-motor or two-motor remotes, limit switch and auto stop, nylon slings, wall mount brackets, corrosion-resistant winders, nylon guide poles, plastic-capped flat wood bunks for pontoon boats, and bunk riser brackets.

These options help improve usability, fit, and long-term performance based on the owner’s specific application.

Neptune Boathouse Lifts are available in multiple capacities, with single-drive and double-drive options depending on boat size and lift requirements. Final specifications vary based on structure, beam layout, travel, voltage, bunk setup, and installation conditions.

The current Boathouse Lift specifications include single-drive models at 4,000 lb., 6,000 lb., and 8,000 lb. capacities, as well as double-drive models at 6,000 lb., 8,000 lb., 10,000 lb., 13,000 lb., and 16,000 lb. capacities. These configurations include details such as cable type, grooved cable winders, travel, voltage and amperage, top beam, lifter beam, standard carpeted wood bunks, and lift speed per minute.

Because every boathouse structure is different, a dealer evaluation is recommended before selecting a model.

Every boathouse installation has its own constraints. Slip width, water depth, overhead clearance, beam layout, dock access, and boat dimensions all affect the lift design.

Neptune Boathouse Lifts can be configured for a wide range of recreational vessels, including center consoles, bay boats, deck boats, fishing boats, pontoon boats, and smaller offshore boats. Adjustable bunks and support configurations help match the lift to the hull shape and keep the boat properly supported between uses.

For pontoon applications or specialty hulls, additional bunk options may be recommended to improve fit and support.

Before a boathouse lift is installed, the structure must be evaluated to confirm it can support the load of the boat and lift system. This is one of the most important parts of the planning process.

A qualified dealer should review beam size, framing design, mounting points, water depth, lift travel, boat weight, and slip clearance. The goal is to ensure the lift is properly supported, safely aligned, and configured for smooth operation inside the boathouse.

This step is especially important for older boathouses, modified structures, or installations where the original framing was not designed with a lift in mind.

A boathouse lift handles significant weight, so regular inspection and safe operation are essential. Owners should inspect cables, winders, bunks, hardware, beams, and structural mounting points regularly. Any signs of cable wear, corrosion, damaged hardware, loose fasteners, or structural movement should be addressed before the lift is used again.

The boat should be positioned correctly each time it is lifted, with attention to center of gravity and proper bunk alignment. Owners should never exceed the rated lift capacity, never operate the lift with people in or under the boat, and never leave the lift running unattended.

Proper maintenance helps keep the lift operating smoothly and protects both the boat and the boathouse structure.

Neptune Boat Lifts provides limited warranty coverage for qualifying lift products and components. Warranty terms may vary by product and component, so owners should review the full warranty documentation for complete coverage, exclusions, and maintenance requirements.

Routine maintenance and periodic service are the owner’s responsibility. Warranty work should be authorized by Neptune Boat Lifts and performed by an authorized Neptune technician or qualified service professional when required.

A Boathouse Lift may be the right solution if your boat is stored in a covered slip, enclosed boathouse, or waterfront structure where a freestanding 4-post lift is not the best fit. It is especially useful when the lift needs to integrate cleanly into an existing structure while keeping the boat protected and fully raised out of the water.

The best recommendation starts with the boat and the structure together. A Neptune dealer can review your boat’s loaded weight, slip dimensions, boathouse framing, water depth, desired travel, electrical requirements, and access needs to recommend the right configuration.
