Its about time someone invented a decent helmet then.

What do racing boat drivers wear ?

It varies - mainly full face - often just motorbike types. A lot of the F1 powerboat drivers wear open helmets - full harness tends to stop you hitting anything!!!

The vast majority of people on RIBs only wear a helmet to keep out the rain and keep their ears warm - a leggy blonde does the same trick.....

That's not really correct - it is believed that the helmet was too large for the victim in the accident. A better piece of reading can be found here: http://www.maib.gov.uk/cms_resources...etin3-2005.pdf

You're right, they are certainly not as substantial as a motorcycle helmet, (however they are much lighter). As the accident that codprawn referred to involved direct contact of the spinning propellor, the helmet, and the victim's skull, the RYA had no option but to cover impact tests in their risk assessment. the RYA now use the motorcycle British Standard for impact protection (in respect of powerboat and RIB racing)... they had no choice really after the accident otherwise they could be found to be negligent in their duty of care if, god forbid, another similar accident ever happened. For day to day leisure use, you need to make up your own mind up about what you're protecting against - is it impact with objects inside the boat, or other more dangerous ones spinning at the transom... your own risk assessment!

Our Geckos have been stored in poor conditions without any damage (we do have the Gecko storage bags) as they do seem to flex quite a bit.

I wasn't aware that the prop had hit his head - didn't see it mentioned in the accident report - lucky he didn't die!!!

Hope this is of some use !!!!!!!

Im still confused ....

.... I understand the possible scoop effect but surley Gecko helmets have found a way around this otherwise why do the RNLI use them? (surley the RNLI have a greater risk of going overboard in the bad weather they go out in...)

No chinstrap I think?

I removed the chinstrap from that pisspot I was wearing on the Folly cruise for that reason-its held on my head by a lace-up webbing part at the back.

No... the Geck helmets have two features designed to avoid breaking your neck (desirable!)
1. The helmet is "cut" high at the rear, so it sits above your neck not on it.
2. The chinstrap is designed to break away at a certain load (like a shear pin).
If you have questions about the design of these helmets you would be well advised to speak to Jeff Sacree at Gecko - he's one of the nicest and most approachable guys in the business.

You need to tailor the helmet choice to the risks anticipated, just like any item of PPE.

The advantage of the Gecko, especially for SAR crews, is that it is pretty good at most things, rather than being excellent at just one. For LB crews, it protects you against knocks, both from your own boat and casualty vessel, it is suitable for helo working applications (winching and downdraught) and has a degree of thermal retention as well. The risk of "bucketing" is there, but very slight due to (a) the high cut design, and (b) the many different mechanisms of entry when going into the water - the drag created by your lifejacket, drysuit or most likely bum is likely to slow you down before your helmet collects enough water to bucket.

However, its all horses for courses - DS Developments helmets are better for pure comms work and impact protection but are heavier, Geckos are a better all round helmet but should never be worn for swiftwater / inland flood applications, and Palm / whitewater types are best for flood or swiftwater work.

Hope this helps

Simon

And there's a third feature I forgot about...
3. The press studs which attach the visor are designed to break away as well. This is why you must keep them coated with vaseline or similar to avoid corrosion as advised in the helmet's instructions.

I would say this is the MOST important - you will not get a "bucket" effect with a properly fitted open face helmet anyway - only from the visor. I would say any visor on an open face would be ripped off or open. I think the "bucket" effect only applies to full face.
