Inflatable vs Traditional Boat Lifts: Which Is Right for You?

After a long day of swimming and sun, nobody wants to scrub weed off the hull before the next trip. A boat lift keeps the boat up out of the water between outings, so it’s clean, dry and ready when the crew shows up with the cooler. This guide compares an inflatable boat dock lift vs traditional lift: how each one works, what each is good at, what to ask before you buy, and how to use a lift safely.

How each kind of lift works

Inflatable (air) lifts

An inflatable or air lift uses buoyancy instead of cables. Air chambers or tanks sit under the boat; a blower fills them with air and they rise, lifting the boat clear of the water. Let the air out and the lift sinks back so you can float the boat off. Most are floating systems tied to a dock, so they ride up and down with the water level.

Traditional lifts

Traditional lifts are metal frames, usually aluminum or galvanized steel, standing on the lake or river bottom. A cradle or bunks hold the hull, and a winch, electric motor or hydraulic system raises and lowers it. You’ll see vertical lifts, cantilever lifts and lifts built into a boathouse or permanent dock.

Inflatable boat dock lift vs traditional lift: the trade-offs

Water depth and bottom

A frame lift needs a firm, fairly level bottom and works within a set depth range. Floating air lifts don’t stand on the bottom, which helps in deep water, over soft mud, or where the level changes a lot through the season.

Installation

Both are real installations. A frame lift has to be placed, leveled and set for your hull, often by a dealer. An air lift must be sized for your boat’s weight and secured to a dock that can take the load. Either way, follow the maker’s instructions or use a pro.

Upkeep

Frame lifts need their cables, pulleys, motor and bunks checked and serviced. Air lifts need their chambers, hoses, valves and blower kept in good shape and watched for leaks. Neither is maintenance-free.

Seasons and ice

Where lakes freeze, many owners pull lifts or take steps to protect them over winter. Ask a local dealer what’s normal on your water.

Cost

Prices vary widely with boat weight, lift type, installation and your site. Get written quotes for both types from local dealers, including installation, permits and yearly service, before you compare.

How to choose the right lift

1. Know your boat’s real weight. Add fuel, water, batteries and the gear you leave aboard to the dry weight, and choose a lift rated comfortably above it.
2. Match the hull. Pontoons, V-hulls and personal watercraft need different bunks or cradles. Make sure the lift fits your boat’s shape.
3. Look at your site. Water depth, the bottom, how much the level changes and how much wave action you get all point toward one type or the other.
4. Check your dock. A floating lift is tied to your dock, so the dock must be strong enough for the extra load.
5. Ask about permits. Lifts are usually permanent or seasonal structures, and many lakes and towns require approval.
6. Ask about service. A local dealer who installs and services lifts is worth a lot when something needs fixing mid-season.

Which one fits your situation?

• Deep water, a soft bottom or a level that rises and falls: a floating air lift is often the easier fit.
• Shallow, firm bottom and steady water: a frame lift is a proven, simple choice.
• A light, flimsy dock: be careful with any lift that hangs its load on the dock; a free-standing frame may suit better.
• A boathouse or covered slip: lifts built into the structure keep the boat out of the sun as well as the water.

Common lift problems and what to check

Most hiccups have simple causes. Start with these checks, and call the maker or your dealer if the fix isn’t obvious.

• An air lift rises slowly or sags overnight. Check the blower, hoses and valves for loose fittings, then look for leaks in the chambers. Weed or debris in a hose can also slow things down.
• The boat sits crooked. Lower it, re-center the boat over the bunks or chambers, and check that the bunks are set for your hull.
• A frame lift is noisy or jerky. Inspect cables for fraying, pulleys for wear and the motor or winch for loose mounts. Don’t keep using a lift with a damaged cable.
• The lift has shifted. Wind, waves and ice can move a lift over time. Check that it’s still level and secured, especially after storms.

A quick look at the start of each month during the season, and a full check before and after winter, catches most of these early.

Using a boat lift safely

• Inspect the lift before each use: lines, cables, straps, chambers and fittings.
• Never go over the rated capacity, and center the boat before lifting.
• Nobody in the water near the lift, and nobody aboard, while it’s raising or lowering.
• Approach slowly and switch the engine off before raising.
• Keep kids and swimmers away from the lift area, and keep life jackets on during docking.
• Secure the boat on the lift, and don’t operate it in storms or strong wind.
• Fix leaks, frayed cables or worn parts right away rather than waiting for the off-season.

Related gear: inflatable docks for swimming

We don’t review boat lifts, so we can’t point you to a specific lift. The products below are not lifts. They’re inflatable docks: floating swim decks you tie to your boat at anchor or float off your dock, for lounging, jumping and climbing out of the water. If you’re setting up the waterfront, they’re the fun half of the project.

• Island Hopper Yacht Dock 10 x 6: a 10 x 6 ft swim deck designed to sit beside a boat, with rubber corner bumpers, an EVA foam top and stainless D-rings. It holds 1,500 lb (people, not boats).
• Island Hopper Patio Dock 15: a 15 x 6 ft floating patio for 10 or more people, with a 12V electric pump and a six-step soft ladder included.

Boat dock lift questions

Is an inflatable dock the same as an inflatable boat lift?

No. An inflatable dock is a floating swim deck for people. An inflatable or air boat lift is a system built to raise a boat out of the water. Never try to lift or park a boat on a swim dock.

Are inflatable boat lifts safe?

A lift that’s correctly sized for your boat, properly installed and well maintained is designed to hold it securely. Stay within the rated capacity, inspect it regularly and follow the maker’s instructions.

Can I install a boat lift myself?

Some owners do, with the maker’s instructions and a few helpers. Many prefer a dealer, especially for heavier boats, tricky bottoms or anything that needs a permit.

Can a boat lift be used in salt water?

Many are sold for salt water, with corrosion-resistant materials. Ask the maker whether a model is rated for salt, and rinse and inspect hardware more often if it is.

What should I do with my lift in winter?

It depends on your climate and lift. Where water freezes, many owners pull lifts out or protect them for the season. Follow the maker’s winter guidance and ask a local dealer what works on your lake.
