Hi Thanks for the quick reply I have read that about 3 times and the official VOSA manual too.
has anyone been to any kind of test like this and what do they do there??

Hi, sorry to be downbeat but you'll likely to struggle to get one through type approval. The rules are pretty tough. It will be mega expensive and too be honest it would be easier to buy one.

Why is that is there something more than an IVA test I need to do??

Much easier just to buy an old one and - ahem - restore it.

But it's the same standards as I was getting equipment tested to in the early 1970's, mid 70's we were getting O2 trailer type approved, remember doing Keith Sinclair's horse box's for him.
Even a new trailer to IVA looks straight forward.

The requirements have changed a few times since the mid '70s

I've never put a trailer through IVA, but plenty of cars. The main IVA problems with a trailer will be getting the necessary "documentary evidence" of compliance for brakes and hitch. The brake (or axle) manufacturer SHOULD (if you go to a good one like Knott or indespension) be able to send you a braking test report to EC Directive 71/320/EC (or maybe ECE Regulation 13), proving that they meet the braking requirements for your all-up weight (boat and trailer combined). VOSA (now called DVSA) will need that. Likewise the hitch - again, worth buying a hitch that is definitely compatible with the brakes you've chosen - again, they'll need proof of compatibility between it and the three sets of brakes, I believe.
However, I seem to remember that boat trailers were a "special case" with DVSA. Can't remember whether it was something to do with the lights. They need to meet positional requirements relative to the extremities of the trailer, but of course, in the case of a boat trailer, the extremities are "the boat"! Also, the lights will need to be e-marked (and not e-marked for a motorcycle or a car. They'd have to be e-marked for trailer use).
Well worth calling their technical helpline (0300 123 9000) and asking to speak to someone about an IV technical question regarding a boat trailer.
Obviously, I could never suggest such a thing, but without legislation demanding compulsory registration and marking of trailers, I don't think anyone would ever know how old it was...
For that reason, I think VOSA have had very few private enquiries for Category O1 (up to 3.5 tonnes laden) trailer IVA tests!

Have you checked width boat / trailer and towing vehicle?, if you take 2200kg as boat weight, you are pushing 3200 kg gross, are coupling / brakes / axles approved for weight and configuration ? are all the lights etc EU type approved ? towbar / trailer stress calculations ?

I thanks for all your replys and thanks halcyon yes everything is calculated boat width etc
Axles are alko axles with plates for 1300kg
here are the links to parts I will be using

max trailer would appear to be 7 M x 2.55 M 27 foot = 8.23 M ?
Axles / brakes / couplings need to have a type approval for use as the set you have, compatibility if not you will probably need type approval.
Lights etc need to have type approval for the application, you will have to show test that they comply.

Auto reverse brakes became mandatory (March 31st 1989). Oh, the posts above have more than a few items to condsider as well since the mid 70s.
The OP mentions a 2.7tonne hitch and a boat at 2.2 tonnes. (OK 2200Kgs) That leaves very little for the trailer mass, considering it's a three axle trailer.
I think the front marker lights are not mandatory for boat trailers.

why do you need 3 axles?

The load can overhang the trailer. The 7m is for the trailer, not the load. Here is a 9.2m boat with a scary overhang...

We had auto reverse, early 70's it was inline with the brake rod, later using the brakes, we were working on these regs from 1971 when 71/320/EEC came out.
What we should have kept was the disc brakes we fitted in the 1960's, the electric brakes were okay, work both ways and no overrun but ideal boat trailers, been there done most and thrown the tee shirt away.

It is, or was when it was designed in the late 90's, a EuroMax trailer sailor - legal to tow in all EU countries - but only just, it's really close. The boat was designed to be as big as possible but still legally road trailerable on a non-commercial basis. It met the regs at the time, but I don't know how they have changed. The trailer is supplied by the manufacturer of the boat and is professionally built.
