ce for boats

Hi guys,
It seems if you make your own boat(s) that the boats need to have a CE.
Is somebody who knows how to do that? Or to find information about it?

thanks for your help,
fce

CE for homebuilders

Hi FCE,

I know that in Belgium you do not need to have the CE for a homebuilt boat.

If you would like to sell it, it is a diff. story. Normally you can't sell the boat within the first 5 years if you had it homebuilt and are not CE. You could sell it when the buyer agrees to tell that he built the boat himself...

If you want to be CE, you will have to buy, find the CE normsheets that apply to the job you are doing. As far a I searched, I didn't find much of them for free.

greetz,

what for you have drawings in your hands in case of a ce-conformity assessment?
Since you build your own boat and do not put it onto the market you are free from any procedure, if you want to sell it it depends on the size which module of assessment you need to choose...anyhow you need to fulfil the given requirements.
Drawings of any other boats won't help you anyway

CE there are 4 cats
a,b,c, d
with a, ocean going
When you build a boat you submit your design and everything else to a certified company that follows the progress from start to finish
here is the company I start to use

CE Marking

The email reply below may prove useful. The vessel I have in mind is the DE25 by Jacques Mertens, for which I have purchased the full plans.

I included in my application to CEproof International, a reference to cold moulding scantlings at

Thanks for the application. It is an interesting project and we'd be very
pleased to oversee the CE marking of your boat. There are, however, a
number of discussion points before we make a formal plan.

The first point is to clarify that there is no legal obligation for you to
CE mark the boat at all. If you are building the boat for yourself, you are
classed as "home-builder". The boats of home builders may be exempted from
the EU Recreational Directive after 5 years from completion. In the 5 years
from completion, you may use the boat but you cannot transfer the ownership.

I am not sure whether you are aware of this exemption or not. Many
home-builders do CE mark the boat, however, in order to (a) keep options
open, (b) have the confidence of a professional to call through build and
(c) to have a third-party mark of approval for when they do come to sell-on.
This is entirely your choice.

The next point is to answer your question regarding materials of
constructions. One of the good and frustrating features of EU Directives is
that they are not prescriptive. This means that anything is acceptable if
you can justify it. So no materials of construction are outlawed but it is
true to say that there is no helpful European standard to pull off the shelf
for this type of construction.

Some certifiers, who are not very clever at structural engineering, may refuse to certify with such a construction as it is beyond their capabilities but that does not make it an illegal construction. We can certainly come up with a means of assessment. There are a number of possibilities depending upon whether this is a planing, semi-displacement or displacement vessel. I am not familiar with your suggested scantling method but I see no reason why a published method would not be acceptable for RCD. We can certainly advise on that and provide secondary calculations if necessary.

The final big issue is the design category. You have stated category B -
Offshore. There are two very significant issues raised by this. The first is
that this requires certification. (Although I referred to certification
earlier, a builder of a boat <12m in category C or D is entitled to
self-certify. If you go to category B, you do need the stability to be
formally certificated and this adds around £700+VAT to the bill - just for
the cert. The second significant point is that to get the certificate, you
will need a stability curve - possibly in two load conditions. I did not
see stability/righting curves on the package contents so we would have to
make these for you. We can do this by inclining the boat and making a
computer model from the plans. This adds another £700+VAT. So category B
rather than C has already added £1400+VAT to the final bill. (Another point
is that I did not see any section drawings. These are necessary to make the
computer model. If we had to measure the hull to make the model, the cost
jumps another £800+VAT.....)

So, is category B essential to you? Most people
only use their boats in category C conditions (ie 2m wave). See our website
for wave spectra in the Channel at
www.ceproof.com/Marine/rcd_design_category.htm.
You could always upgrade the category at a later date if a buyer asked you to do so.

If the boat is in category C, (no formal certificate required but CEproof
documentation and logo on the CE plate) then the price will be £2750+VAT.
For this we complete all the mandatory documents (Technical File, Owners
Manual and Declaration of Conformity), assign formal Craft ID numbers and
issue the CE plate. We also include remote help through the build process,
in between our visits. For category B you must add £1400+VAT and if you
don't have section drawings, another £800+VAT again.

If you would like a formal proposal, please let me know the category and
whether this will be a planing boat or not.

I look forward to hearing from you.

Regards

Considering there are onsite visits included and that any costs could be passed on in the asking price, it's not as bad as I thought, especially if one were to build a series of identical craft under licence, the costs can be further amortised.

Good Reply
did you get my pm?
The Dutch and indeed most are not in favour of certain types as cat B, the are very suspect of canal barges(wide body) and power cruisers under 12.5 m which is quite understandable,
2m waves are common and very uncomfortable whilst 6m waves can be untenable, I dont think Mr and Mrs Dream of our own boat , quite realise how unforging the sea often is
