Bowhunter, you're VERY lucky! Glad you were able to keep your wits about you and make it out alive. However, had it been during the winter, the sudden shock of cold water would likely have produced a different outcome.
Since I had encephalitis last year, being on the water is different than it used to be. Because of the fact that I had a seizure with that illness, and I am on Depakote, I'm really not supposed to be by myself on the water. Even though I only had 2 seizures on the day I was admitted to the ER, and no more since then, because it was viral encephalitis, there is a chance that seizures could develop later on. I hope that prognosis is wrong.....I've managed to defy all the other odds so far.
In the winter time, I am always wearing a type 3 PFD float coat, and a kill switch. Unfortunately, in the summer, I'm a little more lax about it, and rarely wear any kind of PFD or a kill switch. Both my boats are console steering, but even so, I really should get into the habit, especially after reading about your near-miss, and even more so because of my medical condition.
