As Jim notes, when you have two components coming together there is always a risk that they wouldnt release in certain conditions. The ISO has a distinct offset load release test which requires the mechanism to detach when a force is applied from around the body.

The risk of entrapment has been in the sport for a while and it is a constant factor when looking at fatalities within sailing over a period of time.

The solution to this would better be served at the wire rather than the rider, it's the way kiters handle it, either a push or twist release of the attachment point with the facility for easy re-assembly rather than total loss is favoured these days.

Since the early days we've had systems using sailing release shackles, harness loop releases, riderside hook release and now the ISO system which is currently being revised this May ensured a push release system that fires at a given load and is tested mechnically rather than manually which has been prevalent up until now, with the old North licensee owning a patent which is now being contested between the old North (now Duotone) and the new North Technology group who rumour has it are not going to be permitted to use the old North licensees patent but time will tell. However the point to all this is the wisdom in keeping the release mechanism away from the harness then the problems of harness development from multiple companies not complying doesn't arise.

So we need a simple release at the wire, another reason not to release the harness is that some are integral to flotation, they can often be under other devices like rash vests or crash jackets, impact vests and the like.

All logic points to the boat end, but since when has logic ever played a part in dinghy design.

That's all very well, but on a kite board there's only really the one thing to release from. The problem with trapeze hooks is not so much releasing from the trapeze, but getting caught on other bits of boat. I once had a very unpleasant experience when a trapeze hook caught on a reaching hook sailing singlehanded. At least one fatality has been trapeze hook caught on a lower shroud.

Looking at the ISO website, it costs 50-odd swiss francs to read the standard, and it might be futile to buy the current edition as it's nearly due for review anyway.

That's simply served by not having a 'hook' device on the harness, either the ball socket, or the inset v, or even rope spreaders as kites seem to be adopting, probably unsuitable for boats, unless of course the device that clips in is a lot more sophisticated than the current set up. Allthough it could of course just be a hook on the wire instead of at the harness, in which case a rope system would work fine as long as the hook was QD. It's just a question of thinking differently.

In fact the more I think of it as I'm posting this, a kitestyle rope spreader would be a simple cost effective answer, the hook at the wire could even be inverted which would make hooking in easier.

I like the look of the above. I wonder how often sheets would get hooked up on the old trapeze wire as you crossed the boat?

Depnds on the hook I guess, if it had a gated mouth to prevent accidental insertion.

There used to be a sailing device we used for kitesurfing before QR system became available for the life of me i can't remember could it be a Wichard shackle?It would need to be physically released each time, but that wouldn't engage without positive input.

Edit, probably not as effective as I'd imagined but this was the precursor to QR systems that kiteboarders used before there were proprietory systems available to them and they are now seeing a resurgence with the big foil competition kites along with rope spreaders..

I still don't see how you are going to get out the Zhik harness? Do you really need to get out of the whole harness or just let the hook go?
That rope kiter's harness looked interesting, you could tie one end of the rope with a slipping knot that you could pull on end and the rope will come away causing the ring to fall off.
The one think I found a pain in the boat was stuff catching around the many buckles I seemed to have around the back of my hips/lumber. Covered them up with a rash vest and like cycling shorts which helped but only a little.
There are some ba's that have a habit of catching on thinks esp arounf the shoulder straps. May they should be quick release too

Skiff harness (no buckles with a keyball or that kite spreader looks pretty good to me. Add a QR to the wire in case of side loading preventing it from releasing and you're about as safe as you can get. IME you're much more likely to get a leg tangled in something and they ain't quick release.....

Whatever the deliberations are, the rule is approved. You can debate the merits or demerits of it. Like wearing a lifejacket over a buoyancy aid, crack on. However, a new piece of safety equipment will become mandatory in the new rules cycle and as consumers your demand and education is important. As noted, the RYA as governing body has a job to do in Makkah g sure all sailors within its jurisdiction are aware of the changes and how these affect them as early as possible. I would, if buying a new harness, challenge either the seller or manufacturers as to whether it complies with new rules. Protect yourself in many more ways than financial.
