Sue, to settle where some people are trying to drag this argument how fast were you traveling???
Seriously, if the boat was traveling that fast do you really think the kayaker would have walked away??? I think that if I hit a kayak at 25mph in my 30 footer there would not be much left of the kayak or the occupant. I doubt highly that the boat was traveling that fast.
I am sure if a few members that have chimed in would like to be the kayak test pilots there are plenty more that would drive the boat...
