Zonon Yarding Block With Shackle And Pin (3 Ton)

The Zonon 3-ton yarding block is a sturdy, silver-painted cable puller equipped with a shackle and pin for quick attachments. It includes a grease nipple for easier maintenance, helping extend service life in marine environments. Its compact footprint (about 8 x 4.9 x 3.1 inches) fits a 3/8 inch cable, making it suitable for mid-sized boat lifts, dinghy hoists, and tight-duty rigging on docks.
Best for: boaters performing mid-range lifts where a reliable, corrosion-resistant steel block is needed without excessive bulk. This model is a practical choice for dockside maintenance, small sailboats, and aluminum fishing boats.
Caution: ensure proper lubrication around the shackle pin to prevent seizing in salt air and avoid using with loads exceeding the stated capacity. The block’s efficiency relies on correct alignment to prevent rope wear.
Zonon Yarding Block With Shackle And Pin (4.5–6 Ton)

This larger Zonon block expands capacity to 4.5–6 tons, making it better for bigger boats or heavier loads on docks and lifting systems. Built from durable steel with a shackle and pin, it shares a grease nipple for maintenance, ensuring smoother operation under load. Its 5-inch sheave offers more control when feeding cable and reduces rope wear in challenging pulling tasks.
Best for: larger watercraft, heavier lifting tasks, and situations where you need a robust, long-lasting block that tolerates frequent use in outdoor marine environments.
Caution: larger blocks require properly matched winches and lines; mismatching components can lead to inefficiency or rope fatigue. Regular checks for rust or wear are advised in salty atmospheres.
Rocaris M100 Lifting Single Pulley Block

The Rocaris M100 is a stainless steel single-pulley block designed for indoor or outdoor rope applications. Its 360-degree rotation helps prevent rope knotting and provides smooth operation under demanding loads. With a 3300 lb capacity, it suits mid-to-heavy lifting tasks, including dockside rigging and marine hoists. Its stainless construction offers moisture and corrosion resistance for longer service life near saltwater.
Best for: users needing a rugged, corrosion-resistant single pulley for frequent lifting tasks in marina settings, workshops, or boatyards. The 360-degree rotation minimizes rope binding during operation.
Caution: stainless steel parts still require regular inspection for wear and corrosion, especially in highly salted environments. Ensure the rope diameter stays within recommended limits to avoid excessive wear.
YATOINTO 8:1 Pulley System (4400LBS)

The YATOINTO system combines an 8:1 lift with a 4400 lb capacity, making it a strong option for lofting heavier loads. It features upgraded rope, a metal bearing for smoother operation, and a 65 ft reach. The included hardware includes a shackle and high-strength rope designed to handle demanding lifting tasks in garages, warehouses, or boatyards.
Best for: heavier hoisting applications where a high-leverage system simplifies lifting tasks and reduces manual effort. It suits boaters who regularly require lifting bulky gear or heavy equipment onto docks.
Caution: while high capacity is advantageous, ensure the rope and hardware are properly sized for each lift. Avoid exceeding the rated load and check for wear on bearings and pins after heavy use.
FEIMIRE Crab Pot Puller Davit And Pulley Kit

FEIMIRE’s heavy-duty kit combines a 304 stainless steel davit with a 7-inch open-face pulley block and robust mounting hardware. Rated for up to 800 lbs, this setup is designed for crab pots, traps, and other near-sharable lifting tasks on boats and docks. Its corrosion-resistant framing and smooth pulley action help reduce deck clutter and improve retrieval efficiency.
Best for: boaters and dock helpers who need a dedicated, low-friction system for crab pots, traps, or similar loads. The stainless construction helps resist marine corrosion, increasing longevity.
Caution: the 800 lb rating is a ceiling; always verify load distribution and avoid dynamic loads that can exceed the rating during retrieval.
Buying Guide: How To Pick The Right Boat Lift Pulleys And Blocks
- Load capacity: Match the maximum lift to the size and weight of your boat or equipment. Choose a higher capacity if you frequently lift heavy gear.
- Material and corrosion resistance: Stainless steel and galvanized hardware fare better in marine environments, reducing rust and wear.
- Rope compatibility: Check the recommended rope diameter and type. Using the wrong rope can cause wear or failure.
- Sheave size and rotation: Larger sheaves reduce rope wear and provide smoother operation. 360-degree rotation helps prevent rope binding.
- Maintenance features: Grease nipples and accessible pins simplify upkeep in saltwater conditions.
- Mounting compatibility: Ensure mounting hardware and davits fit your boat, dock, and winch setup.
- Portability and storage: For mobile docks, consider compact blocks that still deliver ample capacity.
Frequently Asked Questions
- What is a snatch block and when should I use it? A snatch block changes the direction of the pull and can double the lifting capacity in certain configurations, useful for tight spaces.
- Can I mix brands for a dock lifting system? Mixing components is possible, but ensure you do not exceed any component’s rated capacity and confirm compatible rope sizes.
- Is stainless steel worth the extra cost for marine use? Yes, it resists corrosion better, increasing longevity in salty environments.
- What maintenance steps are essential for longevity? Regularly lubricate moving pins, inspect for rust, check rope wear, and replace any worn components promptly.
- Are there safety considerations with these pulleys? Always use proper PPE, avoid standing under loads, and ensure load is evenly distributed.
