Ovni 365 now reclassified as Cat B

[olewsaa]

I had some email exchange with Alubat in France early this year as we are thinking about a 365. After the new EU-regulation "Directive 2013_53_EU" (finally enforcement January 2017), the 365 is no longer cat A, it require a carbon mast and 200kg extra ballast to be classified as cat A.

All the old 365 will of cause have it's A classification, but if classified by the new rules it would be B. In my view all the 365s are essential cat B. After this re start looking at 395.

Any comments on the new regulation? It might have implications for other yachts too.

It will be interesting to see if this is an isolated incident or if existing Category A class vessels will have their classifications scrutinized.

It would be nice to hear from some NA's if it really means anything anyway. I have heard that it really isn't a good measure of a boats capabilities.

Obvously it a stability related issue with it not now complying somehow. I wonder what has changed.

It might be the rules, or it might be the auditing process catching some creative or wishfull thinking on the part of manufacturers.

I've always wondered how those designs could meet the AVS requirements with mostly internal ballast and a fairly wide hull. Not to take anything away from the boats as by all accounts they are very capable.

I am suprized they didn't go down the usual route of adding some sort of pilothouse to increase the range of stability. And decrease the inverted stability.

It's my understanding that the class A rating is primarily from the STIX rating which is a rating based on resistance to rolling and self righting. The downside is that it doesn't really have anything to do with how well the boat is built nor the quality of components.
I believe that these boats can't be judged the same way as their fin keeled brothers because they are retractable keels which can be raised in storm conditions which means they don't have a keel to trip over when faced with a breaking wave on the beam. These boats tend to slide down the wave somewhat reducing the tendency to roll. They are in other respects built to a much higher level of robustness compared to your average high production cruising boats.

& the comparative areas sort of look scary...

You're absolutely right, only problem is that it might poser problems with authorities and insurance companies if one gets into trouble on the open ocean. They might process the case that the yacht is not suited for the high seas.

There are only isolated cases of capsizing of 365, one outside of Norway some years back. They had not lifted the keel and nobody have told them that they should have done so. (Article in Norwegian :
https://www.seilas.no/innhold/naviga...ticle_id=16560 )

We are think of buying a 365 or 395, and it all started when I looked at the prices for second hand 365 and compared with a new one. Some email with Alubat revielded that after medio Janurary it was category B unless some costly options were selected.

That pushed us over to a 2nd hand 395.

Yes the infamous Stix rating, I wonder if its been tweaked slightly or if the original STIX formula has just now been applied correctly to the design. As far as I recall the stix ratings and categories were self declared by the manufacturer and their NA, with minimal external checks.

I like the Ovni's very much, but I am always concerned slightly about the theoretical amount of time a boat like that might spend upside down if by some chance she was inverted.

the secondhand prices of old ovnis are simply crazy, I don't think they ever get paid that much.
when buying a used one check:
insulation (there were times the yard fitted NONE-condensation was severe!!!)
electrical installation
rudder- & centerboard (please: not "keel", izza plate!) hydraulic (if model has it
cutless bearing (people love to fit brass-sleeved ones...)
(had 3 on the base I was managing in the 90ies)

Please further explain the comment.

the areas under the curve, one being the positive, the other being the negative stability...

I am really upset about standardization. Just leave us alone and keep your ********.
If you drive a car you are allowed to be lefthanded but if you want to own a boat?

Well my ships short specs: 20 tons, 2 Masts 47 ft.v 4,2 litre, max. rpm 1800, hull thickness 1 inch GRP.

Going to trow everything out that is not abdolutely necessary ( air condition and such) nad I am in the 3rd year bringing my baby to my standards. (renew-/upgrade AC/DC a.s.o.) By now I know every screw on the boat.

Pinpointing it: if someone is willing to undergo this procedure he is capable of calculating any risks that may occur and look for him self when he enters another boat. And if not - he should keep off boating before he will be th dangerous part for all out there.

And I would notv even think about any standards. We are talking sbout Ovni and Alubat. do we?

At a first glance: there can be nothing, copy that nothing wrong with an ovni.
Nevertheless and as always I would inspect the boat verx carefully to create my personal report of findings and emergency roles.
