The Sea Guardian: Corrosion Prevention For Painted Aluminium Boats

Sea Guardian System

If you’re struggling with bubbling paint in your alloy boat, you’re not alone.

But there’s now an alternative to repainting…The Sea Guardian.

Put simply, the Sea Guardian is an electronic system, designed to prevent corrosion in painted aluminium boats. 

It does this by applying a negative static charge to the boat, reducing the reactiveness of the aluminium and thus, the rate of corrosion. The article will outline the following: 

Sea Guardian System

What It's Designed To Do:

  • Help protect paintwork and prevent it from bubbling, spidering, lifting or ‘flaking off’ 
  • Slow or stop existing corrosion from further developing or spreading 
  • Help prevent new corrosion from forming 
  • Help prevent galvanic reaction (areas where dissimilar metals meet usually aluminium and stainless steel)
  • Slow paint oxidization (oxidization of paint often leads to dull or powdery paint)

What It Does

Put simply, the Sea Guardian is an electronic system, designed to prevent corrosion in painted aluminium boats. It does this by applying a negative static charge to the boat, reducing the reactiveness of the aluminium and thus, the rate of corrosion. 

The Sea Guardian System is designed to:

  1. Slow or stop existing corrosion from further developing or spreading
  2. Prevent new corrosion from forming
  3. Prevent Galvanic reaction (areas where dissimilar metals meet – usually aluminium and stainless steel)
  4. Help Protect Paintwork and prevent it from bubbling, spidering, lifting or ‘flaking off’
  5. Slow paint Oxidization (Oxidization of paint often leads to dull or powdery paint)

How It Does It

The Sea Guardian system applies a negative static charge to the hull of the boat – as a negative charge is rich in electrons, its able to replace lost electrons in the alloy. This slows or prevents corrosion by lowering the alloy’s voltage potential and as a result, the alloy becomes less likely to corrode. Here’s a picture to make it a little easier:

What Others Have Said:

John:

The size of the corrosion has remained exactly the same, hasn’t grown. The paint hasn’t bubbled up…normally it would bubble higher and higher.

I couldn’t afford to replace it…so it’s simple maths, it’s worthwhile looking after. I honestly was going to strip it all off, repaint it, all around the top, the cabin – not anymore, no way. I’ve got stone chips all out the front from towing. In the past, the stone chips have turned into corrosion. It’s still there, but it hasn’t moved – it’s stopped dead in its tracks, I’m very happy’.

Murray:

‘I had the boat about 18 months – had corrosion come on straight away (within 6 months).The boat I had before got eaten away pretty bad – pretty much all of it. I didn’t want that to happen to this one. 

We’ve had the system on for 12 months, it seems to be pretty good. Hasn’t seemed to be any movement in the corrosion at all. I’m pretty sure you’ve fixed the problem – I’m over the moon really, to tell you the truth.’

Peter:

‘Spidering under the paint, bubbling up – the paint was lifting. When it all starts bubbling – that’s not the right thing to see when you spend a lot of hard work on it.

12 months to today he’s come around and had a look, we’ve gone around it with a ruler. Checked it out with a fine-toothed comb. And the corrosion’s basically slowed right down to nothing – no more existing corrosion has come out since. It stopped the corrosion where it started. It hasn’t grown any bigger since then, and any new points it hasn’t lifted. It doesn’t get any worse or change anything…not like before I am very happy – and it works very well..’

How To Install it

The installation of the Sea Guardian System is a relatively simple one. It can be undertaken by any DIY handyman with a minimum of specialist equipment. 

When installing the system, you have 2 main options: 

1. Installing it yourself by following our full installation instruction manual (download below) 

2. Having it professionally installed by your local automotive electrician or boat servicing specialist. 

This will come down to your level of confidence, time and budget constraints, however, we are confident that most people will be able to fit the system themselves. We have created a complete installation guide which is available for download here, which you can check out prior to your purchase:
