Choose from the fully loaded boat and trailer retrieval conditions, not just the boat's dry hull weight. Sherpa offers Grunter configurations for boats up to about 4,500kg and higher-capacity versions for heavier boats up to around 9,000kg. Ramp angle, rollers or skids, hull condition and whether the trailer is submerged all change the force required. The Grunter uses a purpose-designed gearbox, 12V or 24V motor options and 50mm webbing rather than conventional wire rope on current models. Check the mounting footprint, available battery supply and the straightness of the line between winch and bow eye. If the boat regularly approaches the upper limit, select with a sensible margin rather than relying on the published maximum.

Wide polyester webbing is easy to handle, does not develop sharp broken wires and lays neatly on the short Grunter drum. Sherpa supplies 10m of heavy-duty 50mm webbing on current Grunter models. Webbing still needs inspection because cuts, edge abrasion, UV degradation and contamination can reduce strength. It should feed straight onto the drum without rubbing trailer brackets or the bow roller. Do not tie knots in damaged sections or keep using a strap with torn fibres. If a longer pull is required, use only an approved replacement or extension arrangement rather than adding unknown tow straps into the winch line.

Yes, when the power circuit is designed for the winch's high current demand. Sherpa supplies heavy power cabling and offers high-current Anderson-style connection hardware for the Grunter. The tow vehicle battery and charging system must be in good condition, and the positive and negative cables should be sized for the full round-trip distance from the battery to the trailer connection. Long undersized cable runs cause voltage drop, slow line speed and heat at plugs or terminals. Fit suitable circuit protection and isolation as specified. Do not power a heavy boat winch through a standard trailer lighting socket or small accessory connector. Inspect the vehicle-to-trailer plug regularly for corrosion because it is exposed to road spray and salt.

Salt water is the main enemy. After launching or retrieving in salt water, rinse the winch exterior, webbing, fairlead area and trailer electrical connectors with fresh water and allow them to dry. Inspect the webbing for edge wear and clean sand or shell grit from the drum. Check motor terminals, Anderson-style plugs, control box and mounting bolts for corrosion. Sherpa's Grunter uses corrosion-resistant components and is IP68 rated, but sealed equipment still benefits from sensible washing and inspection. Keep gearbox servicing to the manufacturer's schedule and protect electrical connections with appropriate products rather than packing the inside of plugs with unsuitable grease. A winch cover can reduce UV, road grime and weather exposure while the trailer is stored.

No. The winch is used to retrieve and position the boat; it should not be the only device restraining the boat during road transport. Once the boat is fully seated on the trailer, use correctly rated bow and transom restraints suitable for the boat and trailer design. This removes continuous road shock from the winch, drum and webbing and provides redundancy if a winch component fails. Keep light tension on the bow arrangement only as recommended for the trailer setup. Inspect the bow eye, safety chain and tie-down points as part of the trailer rather than assuming a powerful electric winch replaces transport restraints.
