If you are unconscious you've probably had it anyway.  The bouyancy aid is not for such a situation - so let's put that to one side. 

I want a bouyancy aid where most of the bouyancy is in the water.  I find the high cut ones ride up and most of it is out of the water restricting my view and then to compound it getting in the way when I'm struglling to get on the board.  The only way I can see around this problem is more of the foam lower down on the body and less of it around the front.  Now I don't think it would work very well if it were around my ankles, I think it would be good to have it on my lower back, maybe around the kidneys and a little on my chest.  I'm thinking waistcoats here perhaps high cut at the front to keep clear of the hook.  With that sort of area available surely 50N would be available with a thicknes of about 1cm, and if it were sectioned like an armadilo it would provide great flexibility. 

Better still would be little pockets of air in flexible sachets sewn into a waistcoat - oh just like my old Musto kit from 20years ago!

I'm now going to trawl the web for a picture.  Meanwhile get on with it -manufacturers - you don't seem to have any imagination.

I take it back - some manufacuters are thinking out of the box.  Look at this.

Wearing a rash vest over the top of everything else helps with the riding-up thing. Or you could just get one that fits!

Actually, 50N of buoyancy is next to nothing when you consider the 80 kilos of human it's wrapped round. Whether it's evenly split between front and back or just one panel the person relies on their own awareness to retain their position in the water (although it might not seem like it).

As flimsy evidence - I offer the following. We bought my daughter (the 2 yrs old) one of those swim-vests for holidays last year. It's very similar to a buoyancy aide with several foam panels fitted radially within a neoprene vest. You can take these foam spars out individually but whatever way we tried, every time we put my daughter in the water she would just flip round. Onto her back/front/side, regardless of where the buoyancy was placed. Because she couldn't swim!

Buoyancy aids are worm to give you a bit of help when you first hit the water. If you are in the water for extended periods they mean that you don't have to tread water quite so much. But that's it. 50N won't make you float face up or down.

Redback: is that a legal bouyancy aid or just an impact vest?

If its legal im impressed and let me know where the hell you found it so I can buy one but otherwise its back to my first point: it cant be that big a leap to go from something like that to add another 10N bouyancy to clear the regulations, surely?

Zhik do a slim one similar to that

 

their description; "Slick PFD made for racing fast. No extra unnecessary straps and buckles. Once you have this PFD set to the correct comfort tension you have just the one buckle plus zip side entry. Set and forget.

Back of PFD doesn't ride up and get caught on the boom as you duck under. No more capsizing between tacks because you got caught on something.

Comes in cool grey or black to match the Zhik styling.

Approved to European CE standard EN 393 50 N so it can be raced everywhere."

But we not 80kgs of lead are we - we pretty much float so 50N will make us float no problem ...

Just because we expect a buoyancy aid to look a certain way doesn't mean they have to be like that to meet the EuroNorm.
Not really suitable for dinghy sailing, but this is a perfectly legitimate 50N buoyancy aid. I'm sure they also made a fleece one a few years ago. It would certainly get the jobsworths from the water board who hang around sailing clubs finding reasons to close them down rather excited!
On similar lines, I wonder if anyone has ever attempted to get a wetsuit classified as  a buoyancy aid - they probably almost provide enough!
Incidentally, I don't think there is anything in the rules (unless things have changed recently) that require you to wear an EN393 buoyancy aid when racing, merely "adequate personal buoyancy". Apart from anything else, you won't get the Americans and the Aussies to comply with European Standards!

Many SIs state specifically that a wetsuit is not considered as part of your personal bouyancy.

What you are required to wear when racing will depend on class or event rules. Last summer at the FD europeans there was a big fuss over bouyancy aids as class regulations state what must be carried and the rule had been updated. One of the problems that was that some of the 'small' bouyancy aids arent 50N, they are 45.

One of the things that bugs me about the current designs is that when they have a pocket to keep those handy things in when your on the water (knife, tape, spare shackle etc) its always on the front. And it catches if you have to get on the board.

Mind you Im not sure where else youd put a pocket.
