Back in 1975 I used to take tourists out for rides on a Hobie 14. US$10/hour. Had just convinced a potential customer that you only flip if you're careless, or don't know what you're doing. He said he'd try it after lunch. That was about 90 mins away, so I figure I could get-in another trip before then. I pushed off the beach to go prospecting and was just slumming sitting comfortable on the trampoline looking down when a strong hit me. The 14 took off. It went up quickly on one side and then before I could react to release the the mainsheet, it dove-in deep. You know how those 14s and 16s don't like to come out of the hole. Before I knew it, both rudders came up and over we (hobie and I) went, nose first. I got long gash on my right thigh from hitting one of the stays, but I'm not sure which. It was violent and bloody. Needless the say, my potential customer saw the whole thing. I wonder why he didn't show up for the 12:30 appointment. I could have explained the whole thing favorably. Honest.
