Boat lift types guide
Boat lift shopping usually starts with capacity, but the type of lift matters just as much on a Wisconsin lake, because the four common designs handle depth, bottom conditions, and ice very differently. Here is what separates them and which ones tend to suit Lake Country lakes like Oconomowoc, Pewaukee, and Okauchee.
Cantilever lifts
A cantilever lift uses a simple lever arm to raise a small boat, usually a fishing boat, kayak, or personal watercraft, out of the water by hand or with a winch. It is the least expensive style and the easiest to install and remove seasonally, but it tops out at lower capacities than the other types on this list.
Vertical lifts
A vertical lift raises the boat straight up on posts using a motor or hand crank, holding it well above the waterline. This is the common choice for pontoons and larger runabouts because it clears the hull completely, which reduces hull staining and osmotic blistering from sitting in the water. Vertical lifts need posts set into the lake bottom, so bottom type matters here the same way it does for a stationary pier. See our lake bottom guide for how installers handle muck versus sand versus rock.
Hydraulic lifts
A hydraulic lift uses a pump and cylinders instead of a cable and winch, which generally means less mechanical maintenance over time and a smoother lift cycle. Hydraulic systems tend to cost more up front and are more common on larger or heavier boats where a cable system would need frequent adjustment.
Floating lifts
A floating lift rides on flotation and uses air bladders or a bunk system to raise the boat as the flotation rises, so it does not need posts driven into the bottom. This makes it the practical option in deep water or over a soft bottom that will not hold posts, the same conditions that push people toward a floating dock over a stationary pier.
Matching a lift to your lake
Lake Country's chain lakes vary a fair amount in depth and bottom type even within the same lake. A shallow, hard-bottom bay off Nagawicka can support a standard vertical lift on posts, while a steeper drop-off or a soft bay might call for a floating lift instead. If you are sizing specifically for a pontoon, see our pontoon boat lift sizing guide. If you plan to add a canopy over whichever lift you choose, our boat lift canopy guide covers the Wis. Admin. Code NR 326 limits that apply.
Whatever type you choose, the lift itself has to meet Wis. Admin. Code NR 326 to stay within the DNR's exempt pier standard. See our pier permit rules guide for how that exemption works, and confirm your specific setup with the DNR.
Cost by type
Lift pricing depends more on capacity than on type alone, though hydraulic and higher-capacity vertical lifts sit toward the upper end. See our boat lift cost guide for ranges by capacity, sourced from HomeGuide.
Drive mechanism: manual, electric, hydraulic
Independent of the four structural types above, a lift's drive mechanism affects daily use as much as its category does. A manual crank or wheel is the least expensive and simplest to maintain, but it takes physical effort to raise a heavier boat. An electric motor drive adds cost but makes raising and lowering effortless, which matters more the heavier the boat and the more often you use it. A hydraulic drive, common on higher-capacity vertical and some cantilever designs, offers the smoothest operation at the highest price point.
Frequently asked questions
Which lift type is cheapest to maintain? Cantilever and vertical lifts with a simple cable and winch tend to need the least specialized service, though any lift benefits from an annual check of cables, pulleys, and the motor or pump.
Can I switch lift types without a new dock? Sometimes, if your existing frame and posts can support the new lift's weight and footprint. Have a local installer confirm before you buy.
