Oh man, I just saw this, it's horrible. Condolences to his family and friends.
It's particularly troubling because we had an incident on Saturday when a paddler came off and couldn't remount. Happily in our case he was rescued by a couple in a double... I don't have full details because I wasn't there and whoever it was is keeping a very low profile and I haven't been able to track them down. Our shore party saw some of the drama unfold - the paddler was in cold (for us - 14C?) water for about 20min, being circled by another paddler who didn't seem to know what to do. Eventually a couple went out in a double and somehow they all got back. The conditions at the time weren't particularly difficult - but the forecast was for hectic conditions and someone who couldn't remount should not have been out.
In my experience there's no one system that provides 100% coverage. We've had PLBs fail, I've been in a situation where my calls on VHF went unanswered, etc, etc. So my mantra (aside from the basics of PFD, fitness, remount practise, etc) is to have as many backup systems as is practical.
So I have:
- SafeTRX on my mobile phone in a pouch on a lanyard attached to me
- Waterproof, floating VHF on a lanyard attached to me
- Set of 3 pencil flares on a lanyard attached to me
- Whistle, on a lanyard
- belt leash to the boat
- paddle leash to the boat
I've used every single one of these things, happily mostly to help other people.
And it sounds like a nightmare tangle of shit all attached to me. But I've been using them for a decade and in spite of getting dumped at sea and in the surf, I've never become entangled; most of the stuff sits securely in the front pocket of my Mocke PFD.
And I'm thoroughly familiar with all the kit - I've fired the flares, I've used the mobile at sea; I've used the VHF and I've even summoned help in the middle of a race using the whistle. I've come off in strong winds and waves and had to roll the boat to unwrap my paddle leash. Staying calm is a vital skill.
In my experience the buddy system only works in conditions that it's unlikely that you'll need a buddy anyway - in truly hectic conditions, you can lose sight of your buddy extremely quickly and in a gale you're not going to paddle upwind in any case. So you have to be prepared to take care of yourself - you're essentially on your own, no matter how many other people are on the water.
We're lucky here in Cape Town (at least on the Miller's Run) because the water seldom gets below 16C.
One critical aspect is that you need to be prepared to call for help early - you need to recognise that you're in trouble early and you need to call for help early. Trying for too long to remount can leave you so cold that you can't call for help.
And it's fundamental that you have to have communication system(s) - not only long distance to call for help, but short-range too - because it's so difficult to see a surfski/swimmer from a boat, especially if it's speeding upwind into waves - spray can make visibility near-zero.
Sorry for the rambling stream of consciousness...
