CE Design Categories Explained For Inflatable Boat Buyers

Know what it's rated for.

Somewhere on every boat sold in Europe, there is a small plate with a letter on it. A, B, C or D.

Most buyers never pay attention to it, not knowing that it is one of the most important things on the boat.

That little letter tells you the conditions that the boat was actually built and assessed for. Not the conditions in the website photos. Not the conditions the salesperson describes, but the conditions an engineer has signed off on and tested against a strict standard.

So what is the CE standard, and where does True Kit sit?

What Actually Is a CE Marking?

A CE marking on a boat is a formal declaration that it meets the essential safety requirements of the European Union Recreational Craft Directive.

That directive is not a short document. It covers how a boat is built, how the boat behaves in different conditions, how it handles, how much weight it can carry, how many people it can carry, what engine it can handle, and so on.

It's a legal requirement, not a marketing badge. Selling a boat into the EU without it is not a shortcut. It is illegal.

Why it exists

When buying a boat, most buyers aren't getting the boat surveyed, doing buoyancy and stability calculations, and checking construction methods. They are thinking of what that boat could do for them and how they will use it. Honestly, fair enough; making sure the boat is seaworthy shouldn't be on the customer.

That's why the Directive puts the burden where it belongs. On the builder, before the boat is sold, rather than on the owner, after something has gone wrong.

The four categories, and where True Kit sits

One thing worth understanding about that wave column. Significant wave height is the average size of the biggest one-third of the waves in the water at any given time, not the biggest wave the boat can take. Real water throws up individual waves noticeably bigger than that figure.

The letter gradings are given based on the conditions that the boat is suited for.

True Kit's boats are all Category C.

Why we sit at Category C, and why it matters

Plainly, Category C is an honest rating for any portable boat.

We build our boats to handle wind Force 6 and waves up to 2 m.

That is what a real portable boat should be built for. It is also where small boats most often get into trouble. Small boat incidents concentrate close to land, in bays, estuaries, bar crossings and coastal waters, not far offshore. That is exactly the water Category C describes, which makes it the rating that matters most for a boat like ours, as it is built to handle those conditions.

That being said, we do not recommend going out and chasing 2 m waves. Just because we build our boats to this standard doesn't mean you are safe in unpredictable waters, and we won't pretend otherwise. You should only go out in water conditions that you are comfortable with and have experience navigating.

We build boats to explore coastal waters, harbours, estuaries, bays, lakes and rivers, in conditions you would sensibly choose to head out in, and it is where the overwhelming majority of our owners actually spend their time.

Category C is not a runner-up prize. It is a specific engineering standard that we worked hard to meet. It gives you the peace of mind that your boat will handle what we say it will.

Being straight about what a plate can and cannot do

We are not going to tell you a CE plate keeps you safe on its own. You would be right not to believe us.

What a CE plate tells you is that the boat was assessed against a written standard rather than against somebody's opinion. Whether it stays afloat when it fills with water. Whether it stays upright with four adults and gear on one side. Whether the maximum load printed on the plate is a tested number or a hopeful one.

It's the difference between saying "we think the boat will handle this" and "we know the boat can handle this."

But there is a question sitting underneath all of that, and it is the one almost nobody thinks to ask.

Who actually did the assessing?

The catch almost nobody explains

Here is the part the industry does not advertise, and it applies to nearly every inflatable on the market.

How much independent checking a boat gets depends on its category and its length.

• Category A and B boats must involve an independent third party, called a Notified Body.

• Category C boats between 2.5 m and 12 m can be assessed by the manufacturer themselves, provided the design meets the relevant published standards.

• Category D boats up to 24 m can largely be self-assessed the same way.

Read Category C again. It covers almost every inflatable you are looking at.

A builder can fit a Category C CE plate to their boat having checked their own work against the standard. No independent surveyor. No on-water testing. No third party asking questions about swamped stability or what happens at maximum load.

The plate looks the same either way. So does the paperwork.

Which is why "is it CE certified?" is not a useful question, because almost every seller can say yes.

The four questions that separate builders

Ask these of us, and of any other builder, to make sure your future boat meets these standards.

1. Which standards was it assessed against? For inflatable boats, you want to hear ISO 6185. For stability and buoyancy on boats under 6 m, ISO 12217-3.

2. Was a Notified Body involved, and what is their number?

3. Was it physically tested on the water for load and swamped stability, or assessed on paper?

4. Can I see the Declaration of Conformity?

A builder whose boat complies with the CE standard will answer without hesitating.

A builder who does not will change the subject.

True Kit boats are tested on the water, including physical payload and stability testing, rather than certified from a desk. Our certification was done by HPI Verification Services.

What you actually get out of it

• A tested load limit. The maximum load is the figure the boat was assessed at, not an estimate.

• Legal sale and registration in the EU and EEA. An uncertified boat cannot be legally sold or registered there, and that becomes your problem rather than the builder's. Outside Europe, CE is not a legal requirement, which is exactly why it is worth asking for.

• A documented paper trail. The Declaration of Conformity and owner's manual are what surveyors, insurers and future buyers ask to see.

• Stronger resale. Complete paperwork sells a boat.

• A detailed owner's manual, covering the limits of the boat.

• Confidence that your boat is built to last and to the correct standards.

What to check on the boat itself

Find the builder's plate. It must show:

• The design category

• The maximum recommended load in kilograms, covering people, gear, fuel and the outboard

• The maximum number of persons

• The maximum rated engine power and maximum outboard weight

Then confirm the owner's manual exists and that the Declaration of Conformity names the correct standards.

While CE certification is an EU standard, it is widely recognised globally as a benchmark for safety. Before purchasing your next boat, always verify that it is CE compliant and that the builder can provide the documentation to back it up.

Remember: a Category C rating is the limit of what a hull is designed for, not a recommendation to head out in challenging conditions. Regardless of your boat's rating, your safety depends on a boat in good working order, a competent crew, and proper safety gear like lifejackets. Your judgement is your primary safety system; make sure to use it.

Every True Kit is Category C, tested on the water, not just on paper, and built for the conditions where most owners actually spend their time.
