You may possibly be right but in my experience I would have to disagree with you.

I can't think of any around here and there are plenty of ribs.

I doubt if Cobras add up to any significant number on the Solent either, as a % of total number of ribs.

In my humble opinion ... In normal use why would you ever need to turn sharp enough and fast enough for hooking to occur? The tightness of the turn required can be seen in the video and can only happen by intention. If you were towing a wake boarder/water skier/ringo etc. then you would know tight turns were involved and take the necessary precautions. I agree with all the comments that the danger does not lie in the design of these ribs but with the use of these ribs.

In the Padstow case there was a last minute change of direction made because they didn't think they would clear an obstruction. SO... Yes it was an intentional manoeuvre but that didn't mean they understood the consequence of it until too late.

Yes if you do tight turns all the time you will get used to how it behaves. If you only do one High speed tight turn you may discover at the wrong moment.

Kill Cord - the padstow guys normally used theirs. They had PB2. They just forgot during a helm change. The needles incident it was not the helm who went over.

I'm not sure if there is something fundamentally wrong with Cobra Ribs. BUT if I was about to get on a plane and AAIB said they should change the landing gear and they said 'nowt wrong with the gear if used correctly' would I get on the plane? There are three options in my opinion why they haven't changed:

1. There is genuinely no way to make it better. I'd like to see what they tried.

2. There is genuinely no issue. I'd like to see the head to head comparison between it and competitors.

3. They know changing going forward opens up (a) consumer liability to fix previous models (b) (some) liability for the deaths.

Did the changes made to design in the past make hooking worse?

Aren't there two fundamental questions:

Will any 8m rib "hook" if driven into a tight enough turn at a high enough speed?

Does the particular model of Cobra do this at a significantly lower speed and wider turn?

I suspect the answers are "yes" and "no - but a little lower and a little wider because of a hull that is slightly flatter than most".

You'd hope so, but I wouldn't want to rely on it. Anyone can tow something behind their boat, but it doesn't necessarily follow that they are competent.
