New MAIB Safety Digest - including RIB incident

http://www.maib.gov.uk/cms_resources...re%20craft.pdf

Last "article" includes the findings of the RIB accident originally reported on RIBnet here http://rib.net/forum/showthread.php?t=14245

All the usual stuff about drinking and boating, understanding the handling characteristics. However their are also comments on the suitability of the life jackets worn (both were wearing PFDs).

The driver WAS wearing the kill cord - but the MAIB imply that as it was attached round his WRIST it got tangled and so failed to operate.

Always useful reading - learn by the mistakes of others.

They weren't both wearing PFDs - the poor bloke who died was wearing a 150N lifejacket - but a manually inflated one. For some reason he didn't inflate it even though he was alive for a while. the person who survived WAS wearing a PFD so you could say a PFD is better than a manual 150N jacket!!!

As to the kill cord it could just as easily got stuck around something if clipped on elsewhere.

They mention drink as a factor but I am not so sure. He was 2x the road limit for driving but that didn't seem to be a factor. This was a tragic ACCIDENT and I don't think any amount of hindsight could have prevented it.

I was using PFD in the generic sense of "personal flotation device" as they would (I believe) in the US (and I think elsewhere too) - which covers both bouyancy aids and life jackets. Appologies if I confused you.

I'm not convinced of that. I do think it is more likely to get tangled round the wrist. But I think the point is - if it is securely attached to leg or PFD then it is much less likely to come off during "ejection" than if it only has to slip off the wrist.

They certainly didn't dwell on it the way they have in other reports. But they do suggest it may have contributed to the initial event in the chain. It may also have contributed to the driver not inflating his life jacket and/or his ability to survive whilst awaiting rescue.

I agree it was an accident but I think there are lessons to be learnt and declaring something as simply an accident suggests the outcome cannot be avoided in the future - which contradicts your opening statement:

I have read the report and take issue with the statement that it was a nice spring day. I was out on a RIB that day in the West Solent during lunch time. Having launched in Southampton I went to the Needles, visited yarmouth briefly and returned to Southampton. In my view it wasn't a very nice day at all. Okay it wasn't raining but it was breezy and it was cold. Off the Needles there was a big swell, with large rollers coming in. Bad enough for me to not hang around in them. I did hear of this report later on when I got home and I immediately thought that if the guys were in the drink for more than 10 minutes without a drysuit they would probably die.

Without seeing the proper report which is usually very detailed it would be unfair to pass judgement on anything that happened that day. This report is almost like a poster. Usually the reports are very detailed and it seems this one is missing much of the finer print.

My own experience moves me to disagree with you here - I've tried various points for attaching the killcord and found that the wrist was the worst, the lifejacket the most secure but most difficult to attach and detach, and around the knee to be the best as it has never snagged on anything for me.[/I]

I think that you'll find that you're contradicting medical fact here - IIRC you are more at risk of hypothermia if you have been drinking. Where's that Manning bloke when you need him?

As with all reports its always good to be wise after the event. sorry to hear someone died, but if we worried about every risk we took wouldn't life be boring.
Whats worrying is the fact that the killcord didn't work, which left the two guys without a means of getting out of the water, because the boat carried on its merry way, and subsequently one of the poor guys froze to death.
Irrelevant of alchohol issues or lifejacket issues to me the kill cord working properly might have saved them.
Thats the issue that should be looked at more in my mind, and its probably one that should be thought about more by all us RIBSTERs than anything else.
Being in a high speed boat in rough seas is fun but when you fall out of it some means of getting back in is required. I have often mulled over this because I have personal experience of struggling to get back in to a RIB. Firstly I think we need to make sure the killcord is going to work. Then we need a means of getting back on the stationary boat. I don't think swimming is one of those options unless its dead calm. My answer would be to have an extending line on our lifejacket that we could pull on to get ourselves back to the boat. And by extending line I mean one that is perhaps 50 meters long and not one that the yachties use. It might not be feasable most of the time but if your going to have some fun in big waves then I think it should be considered part of your safety equipment along with a lifejacket and for us RIBSTERs a drysuit.

Absolutely correct. Alcohol will cause the blood vessels at the extemities to dilate which will take blood away from the body core. You will 'feel' warmer, however body core temperature will drop much more quickly.
