Helmets

Rib Helments

Ive been looking at the John's SUM and Gecko and Gath helmets. I dont think the SUM is for me (a bit too radical) so that leaves the admittedly more expensive Gecko or Gath options.

The question arises about spray getting past the visor, Ive seen the Gecko and know there is a possibility of water dribbling down the inside from the top. The Gath helmets visor looks (from the few pics Ive seen that the visor retracts into the helmet - does this stop spray ingress?

The other question is about neck spinal damage inflicted if you hit the water wearing a helmet. Please correct me but I would assume the Gecko helmet with its inflatable liner prevents water ingress stopping the head from being dragged / whipped on impact (is that why the RNLI use them???)

However has anyone looked at the Gath helmet from this point of view?

Pete

Pete,

Hi. I have the Gecko which I've used on and off for a few years now. I have never had a problem with water dribbling down from the top, inside. I have had a problem with one of my two helmets having a visor that doesn't like staying up and has a habit of flopping down which is annoying. Biggest problem though is the fact that I have the short visors fitted, this allows spray to soak your chin and neck. I am considering buying another helmet in the New Year and I'll make sure this one has the full length visor.

Thanks That was another question about long or short visors. Did you find a workaround for the flopping visor?

Yeh I make sure my passenger gets that one

Seriously though I have found also that if you don't service the helmets with a little bit of vaseline on the studs they corrode slightly making them hard to work with. I'm going to bring the helmets in today and give them there annual sevice. I think I should be able to sort the problem one quite easy with a pair of pliers.

RIB's & Helmets

Cant quote chapter and verse but Trials and Studies by the Institute of Naval Medicine are quite conclusive. They recommend that helmets are not worn in RIB's or vessels travelling at high speed. The scoop effect caused by the helmet as it hits the water could in their opinion cause significant spinal injury. However they do recognise that the helmet will protect the wearer from injury due to impact whilst they are in the boat.

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

Depends on the type of helmet and how it fits. I would say a full face is far more prone to this - a well fitting open face would just have the visor ripped open/off.

The problem though is that facial injury is far more likely with an open face if you hit the console etc.

Maybe JK's alien masks are the ideal solution?

I've used the Gath's with the integral visor. No problem with spray ingress, and no problem with steaming up either - as the bottom of the visor is actually several inches from your nose and mouth.

The Gecko strap system is designed to break-away at a certain force - so that there is no chance of "bucketting" or the "scoop effect" as the helmet is simply ripped off your head.

Gath's have several sizes and are designed to be much closer fitting... I am unaware whether or not their strap is designed to break-away in the same way as the Gecko. However, because the volume of the helmet is a lot smaller, and the gaps for water ingress a lot narrower, the bucketting effect will be correspondingly reduced, also, they do have vent holes in the top, again reducing the potential scoop forces - although they are covered if the visor is retracted.

I think I'm gonna treat myself to the Gath Gedi for New Year.

There was a bad accident using a Gecko helmet because it WAS ripped away.

The Gath looks good and its a bit cheaper than the Gecko. However I don't think its the helmet for me. I wear a helmet primarily for when its persisting down and I think if I was out for any length of time with the Gath I would be fed up with water coming through the breather holes in the top of the helmet. I also have a habit of ducking when a ton of water comes over the top so would be exposing my bonce even more to getting wet. Personally I think the Gecko is the best, its just too expensive. Although I haven't broken one yet they don't seem as substantial as a motorbike helmet and I should imagine they could be cracked if roughly stored with heavy objects. Then I would be hacked off to find I'd broken one.

In a real world situation an Ocean Dynamics Rib capsized in heavy white water with 12 pax on board. There were no serious injuries which is prob down to the fact the pax were all sitting on the tubes so were thrown clear. Also they were wearing canoing style whitewater helmets which must have helped a lot.
