hit your head on the way in and a life jacket ain't gonna help much, still need to swim out from the rocks to avoid getting bashed around. If you think you need a life jacket then obviously its too rough to be fishing that spot, and if you can't swim you shouldn't be fishing off the rocks anyway, a bit of commonsense is needed.
I fished the same Catho area were the car was found on sat arvo, swell was up then with a swell direction that was wiping out normally safe rocks, and swell was building, i could of told you it wasn't a smart idea to fish the area of a night time as could most well experienced rock fishos.
