I have a similar story about a Hobie 18 that went turtle. When I was living in Hong Kong, sailing a Dart 15, a buddy of mine capsized in his Hobie 18. I was on the beach and after seeing him struggle to right it for about 10 minutes, I set off with a burly partner to try to help. I circled as my partner jumped in to lend assistance. Little did we know that leaks on alone the V chine on the bottom of the hulls ((from repeatedly being dragged across coarse sand and, well, from lack of maintenance) had filled one or both hulls. It was all but impossible to right the thing. We probably spent an hour out there before we managed to get the mast to point skyward again and limp back to the beach. If it had happened in anything but warm tropical waters, we''d have been forced to abandon the boat or risk hypothermia!
