One winday fall day I took my then girlfriend and my sister out on the Hobie 16. Once we got out to open water, we spent the next half hour on screaming reaches, flying the hull. My girlfriend, who'd never been on a Hobie before, asked "What keeps us from tipping over?". Seeing as how both she and my sister were just passengers, and I was doing all the work, I responded "I do", whereupon, a slight gust hit us, I failed to compensate, the boat eased up into that "there's nothing you can do now but wait and hope" position, and proceeded to go over. My girlfriend and sister are sliding across the trampoline into the water. Because my sister has limited use of an arm due to a recent stroke, I dive across my girlfriend and grab my sister to make sure she won't go under. My sister's laughing hysterically. She's been through this drill hundreds of times, and doesn't seem to need any rescue. From then on, my sister jokingly claims that was the beginning of the end of the relationship with that girlfriend.
