You'll will find as they are not approved under Aust Standards...
That's interesting. I've used and tested pencil flares on a couple of occasions and they were very effective.
I used them in anger to call for help when a friend got into trouble; they were seen by multiple people on shore and the NSRI were called.
When we did our sea-rescue exercise with the NSRI, we got permission to fire some, and they were found to be effective - particularly for the helicopter who reported that the smoke trail acted as a pointer to the paddlers.
The beauty of them is that they are so compact - they weigh nothing and can easily be stored in your front PFD pocket.
Smoke flares may well be even more effective, but for surfski paddlers they are bulky and cannot be carried on your person - so overall their effectiveness is reduced.
No safety measure is 100% effective, but every measure you take adds a little to the odds of your survival.
There are a number of things about the WA safety regulations that I think are wrong for surfskis. For one thing leashes are vital - and they're not even mentioned.
