Frequently Asked Questions

Q: What’s the maximum load it can handle?

A: 1150kg, which makes it ideal for extra-large boats and heavy trailer setups.

Q: What’s the benefit of having three gears?

A: The 12:1 gear gives maximum torque for heavy loads, 5:1 is for moderate loads, and 1:1 is for fast rewinding after launching.

Q: How does the magnetic handle work?

A: It clicks securely into place and stays there—no popping off during use. You remove it only when you want to.

Q: Is the strap long enough for deep ramps?

A: Yes, the 7.5m UV-coated webbing is extra wide (65mm) and perfect for long-distance winching.

Q: Does it have a brake system?

A: Absolutely. It comes with a smooth launch-control brake and quick-release lever for safety and ease.

How to Measure Winch Load Rating – What Does It Really Mean?

When choosing a hand winch for your trailer or boat, it’s crucial to understand what the rated capacity (also called “load rating”) actually refers to, and how it’s determined. Let’s break it down:

1. What Is a Winch’s Load Rating?

The load rating is the maximum weight a winch can pull under ideal conditions on a level surface, assuming no friction. For example, a winch rated to 900kg means it can pull up to 900kg of rolling weight.

Important: This is not the same as lifting weight vertically – it’s pulling a load across a surface (usually a boat hull on rollers or skids).

2. What Is It Measuring?

• It measures the pulling power of the winch itself (the gear system strength and crank leverage).
• It does not measure the load your trailer can carry – that’s a separate rating.
• It does not mean your boat or vehicle has to weigh less than 900kg – more on this next!

3. How Do You Choose the Right Winch for Your Boat?

Here’s a basic rule of thumb:

Winch rating = 1/2 to 1/3 of the boat’s total weight

Why? Because most trailers have rollers or skids to reduce friction. A 1200kg boat on a roller trailer might only need a 400–600kg rated winch.

But if you’re using a skid trailer or launching uphill or on grass, increase the winch rating to be closer to the boat’s weight.

4. Factors That Affect Pulling Power

• Friction: Boat slides on rollers easier than skids.
• Incline: Pulling uphill increases effective load dramatically.
• Winch Gear Ratio: Higher ratios (e.g., 12:1) = more power, less speed.
• Length of Strap Out: More line out = less mechanical advantage due to drum diameter change.

5. What Happens If You Underrate or Overrate?

• Underrated winch = heavy cranking, risk of breakage or failing gears
• Overrated winch = okay, but heavier, more expensive, and sometimes slower

6. What About Dyneema vs Steel Cable vs Webbing?

• Dyneema Rope: Super light, strong, safe to handle, floats – great for marine use
• Steel Cable: Strong but heavy, can fray, needs gloves
• Webbing Strap: Easy to handle, won’t kink, ideal for light to medium boats

7. Final Summary – Who Needs What?

Pro tip: Always check that the winch is mounted securely to a strong point and use quality mounting bolts!
