Just found a link from the forum at Advanced Elements to another forum -- this one for motorhome enthusiasts. The post it links to is from one of their senior members, Nigel, who is also into kayaking. He tells how he was run over by a power boat a few days ago.
Scroll down through the well-wishing to see Nigel's description of his decision to capsize and how his feet were injured. He's lucky to be alive. If Nigel hadn't capsized, the injuries (which were bad enough) might have been to his head. And if the yobs who ran him over hadn't stopped to help him, Nigel probably wouldn't have made it to shore on his own.
Memo to self:
-I'm invisible in my kayak. Yes, this colourfuly-dressed person in a bright kayak is invisible.
-Larger boats might move faster but are unable to steer out of MY way, I must stay out of THEIR way.
-My kayak's place in the spectrum of boats from floating log to ferry is solidly in the "speedbump" category.
-When a collision with a high-speed boat is inevitable, roll over (away from the approaching boat) to take the blow on the hull instead of my upper body. It's possible the fast boat will slide over my kayak, and push me down for a second or two.
