Boat Lift Sizes: How to Select the Right Boat Lift Size for Your Boat | HydroHoist

Let’s be honest, as valuable as they are to preserving your precious vessel, shopping for boat lifts isn’t exactly the most thrilling part of owning a boat. You’d probably rather be out there exploring coves or reeling in the catch of the day. But here you are–researching boat lifts because you understand that nothing sinks the joy of boat ownership faster than a sluggish engine caused by a waterlogged hull or persistent biofouling.

Below, we walk you through the essential considerations for finding the optimal boat lift size and capacity to help keep your vessel protected and primed for many smooth launches ahead.

Understanding Boat Lift Capacity: Key Factors to Consider

Boat lifts are rated for specific weight capacities. The lift must be strong enough to handle not only the dry weight of your boat but also additional weight from fuel, water, gear, accessories, and other equipment typically stored onboard. For reference, 600 gallons of fuel and 200 gallons of drinking water can add over 5,300 lbs to the boat’s weight (Ita Yachts Canada, 2024). We recommend getting a lift with a capacity of 20-25% more than your boat’s dry weight. 

 

Many seasoned boaters will even suggest getting the highest capacity lift you can afford to account for future enhancements or the inevitable upgrade.

Measuring Your Boat: Essential Dimensions for Boat Lift Selection 

Measuring your boat accurately is crucial for selecting the right boat lift. Here’s a quick guide: 

 

  • Length: Measure from the very tip of the bow (including any structural extensions like a pulpit or bow spirit) to the stern, ensuring the measuring tool runs along the boat’s centerline. Include any permanent extensions, such as a swim platform or integrated outboard bracket, as these add to the boat's overall length.
  • Beam: The beam is the boat’s maximum width, which is often found at the midpoint or slightly forward of the midpoint of the hull. Use a measuring tape to go straight from one side of the boat to the other at this widest point. Be sure to include any fixed structures like rub rails if they extend beyond the hull, as they contribute to the total width. When adding guideposts, you also want at least a 10-inch cushion.
  • Height: Measure from the lowest point of the hull (usually the keel) to the highest fixed point on the boat. Don’t forget to account for fixed structures like T-tops, radar arches, or wakeboard towers. If the lift will operate under a roof or structure, measure from the waterline to the highest fixed point to ensure enough clearance when raising the boat.
  • Draft: This is the depth of the hull below the waterline. Identify where the boat's hull meets the water when floating under normal conditions and locate the deepest point of the hull below the waterline. On most boats, this will be the bottom of the keel. If your boat has an outboard or inboard motor, ensure the motor is tilted up and not included in the draft measurement.

 

These measurements help ensure the boat fits securely on the lift without overhangs or balance issues. 

Matching Your Boat Type to the Ideal Boat Lift 

Your vessel's size, shape, and weight distribution all play a role in determining the boat lift type that provides optimal support and performance. For example, pontoons typically require wider platforms and cradle support to prevent stress on toons. In contrast, larger vessels, such as sailboats or powerboats, often need deeper lifts with keel clearance. Meanwhile, watercraft with unique features—like deep-V hulls or wide beams—require adjustable bunks to support their distinct hull designs.

Considering Water Conditions and Dock Location 

Assess your waterfront conditions, including water depth, bottom composition, and other environmental factors that may impact installation and operation. These conditions will help you determine the most suitable type of boat lift and the appropriate anchorage solutions. For instance, while a vertical lift may be easy to install in more shallow waters, floating boat hoists may be better suited for areas with deeper or fluctuating water levels.

 

Your dock setup must also be robust enough to support the weight and movement of the hoist while leaving adequate space for boarding, disembarking, and maneuvering your boat. Ideally, you also want a location that provides shelter from strong waves and winds to avoid straining the lift structure and your boat. 

 

Thoroughly assessing these factors will help you choose a solution that provides a seamless fit, reliable operation, and long-term protection for your boat.

Installation and Maintenance Considerations for Your Boat Lift Size 

A well-maintained boat lift could very well be the last one you purchase. Here are some maintenance essentials to keep your lift in prime condition:

 

  • Regular Inspections: Conduct periodic inspections of the entire lift structure, checking for any signs of wear, damage, or corrosion. Depending on your lift type, this can involve inspecting the power source wiring, hydraulic fluid levels, or flotation tanks. 
  • Lubrication: Regularly lubricate moving parts and pivot points to prevent rust and corrosion. When moving parts dry out, they start to rust and usher potential issues. 
  • Periodic Cleaning: Regularly rinse the lift with fresh water and mild soap solution to remove dirt, debris, and any buildup of algae or marine growth, using a soft brush to scrub away stubborn spots.

Different boat lift types may have specific maintenance requirements. Always adhere to the manufacturer’s maintenance recommendations to preserve the lift's longevity, safety, and performance.

FAQs

  • Can I install a boat lift myself, or do I need professional help?

While there are numerous DIY tutorials online walking you through boat hoist installation, we always recommend hiring a professional to tackle the project, especially if it’s your first install. Boat lifts are complex systems with several moving parts. Incorrectly setting up a boat lift can pose safety hazards that can damage the lift and your boat or cause injury to yourself and others. 

  • How much does a boat lift typically cost?

The cost of a boat lift can vary widely depending on the type, size, and features, with prices ranging from $1,500 to over $20,000. Smaller lifts for personal watercraft or lightweight boats typically cost between $1,500 and $3,500, while mid-range lifts for boats up to 10,000 lbs can range from $5,000 to $12,000 (Brady, 2023). High-capacity or specialized lifts, such as hydraulic or floating lifts for larger vessels, can exceed $20,000. 

You will also need to factor in installation costs, which can vary depending on the complexity of the installation, including factors like water depth, bottom conditions, and dock type.
