A: It’s rated at 900kg, perfect for large boats and serious trailer loads.
Q: What’s special about the magnetic handle?
A: It locks into place magnetically and only releases when you want it to—safe and secure during use.
Q: How many gear speeds does it have?
A: Two! A 5:1 gear for heavy pulling and a 1:1 for fast rewinding.
Q: Is the strap long enough for boat ramps?
A: Yes, the strap is 7.5m long—ideal for most ramp lengths.
Q: Is it saltwater resistant?
A: Absolutely. Built with rust-resistant components and sealed bearings for marine use.
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?
Boat Weight | Recommended Winch Rating | Ideal Strap Type |
---|---|---|
Under 500kg | 200–300kg | Webbing |
500–900kg | 400–650kg | Webbing or Dyneema |
900–1200kg | 650–900kg | Dyneema or Steel |
1200kg+ | 900–1150kg or more | Dyneema or High-Rated Webbing |
Pro tip: Always check that the winch is mounted securely to a strong point and use quality mounting bolts!
