Boat lift repair in Jupiter

Common boat lift faults

Stop using the lift if you see frayed cables or the boat sits unevenly.

• Motor hums but the lift does not move
• Lift raises unevenly or one side drops
• Frayed, kinked or flattened cables
• Grinding from the gearbox or pulleys
• Corroded switches and wiring

Lifts sit parallel to the bulkhead

Town Code 27-2626(b)(11) requires docks, boat lifts and personal watercraft lifts in canals to sit parallel to the bulkhead. A lift set at right angles to the wall is not allowed on a Jupiter canal without a dock waiver.

A repair keeps the lift where it is; moving or enlarging it means meeting today's rule.[1]

Inlet tide on the Loxahatchee

NOAA's Jupiter Inlet south jetty station records a 2.39 ft mean range and a 2.75 ft great diurnal range, with mean higher high water about 0.19 ft above NAVD 88 (1983 to 2001 epoch). Lift travel and floating dock gangways near the inlet are planned from this gauge.

Repairs are scheduled when the cradle can be worked on above the water.[2]

Half the waterway stays open

Jupiter keeps a centreline channel of 50% of the waterway width unobstructed, or at least 15 ft where that is impossible, and allows only rectangular, T and L docks unless the Director approves another shape. Piles for docks and lifts are laid out against that channel line first.

Lift repairs often turn into pile repairs, which bring the piling rules with them.[1]

What makes Jupiter different

Town Code 27-2626 keeps half of every waterway clear: a centreline channel of 50% of the waterway width must stay unobstructed, or at least a 15 ft channel where that cannot be met. Only rectangular, T and L shaped docks are allowed unless the Planning and Zoning Director approves another shape.[1]

Who approves what

The Town's checklists ask for FDEP self-certification or exemption verification, Army Corps approval if not included in the DEP decision, and SFWMD approval for structures on submerged lands or in natural waterways such as the Loxahatchee River, the Intracoastal Waterway and Sawfish Bay.[3][4]

Permits in Jupiter

• Town of Jupiter Building and Planning and Zoning: Marine structure permits; dock waivers under Town Code 27-2626.
• Florida DEP or South Florida Water Management District: FDEP self-certification or exemption verification for canal docks; SFWMD approval for structures in the Loxahatchee River, the Intracoastal and Sawfish Bay.
• US Army Corps of Engineers, Jacksonville District: Army Corps approval where the FDEP decision does not include it, as the Town checklists note.

What causes most failures

In salt water, galvanic corrosion attacks metal parts, which is why sacrificial zinc anodes need regular replacement. Cables should be checked for fraying, corrosion, kinks, flattened sections and uneven tension, and pulleys and gearboxes need lubrication.[6]

Repair or replace the lift?

If the frame and beams are sound, replacing the motor, cables or gearbox is usually far cheaper than a new lift, which ThePricer puts at $7,000 to $14,000 installed for a 10,000 lb four-post model in South Florida.[7]
