Drowns in Spill From Speedboat; Glen Dristy Victim Of Mishap At Turlock Reservoir; A speedboat enthusiast who could not swim. That summed up the story of Glen Dristy, local mechanic, who was drowned Sunday afternoon in the Turlock Irrigation District Reservoir when his outboard motorboat threw him out. The fatality occurred despite the heroic effort of Dave Goldstein, 17, who almost gave his own life in attempting to save Dristy. The two had gone to the reservoir that afternoon to try out Dristy's boat, which he had been working on in his spare time in an ambition to build the fastest speedboat in the county, a goal which he was close to achieving. With Dristy at the tiller, they were making fast speed when another craft passed across their bow and they struck the wave from its wash, causing Dristy's boat to rear up and throw him into the water some distance away. Goldstein managed to hang on, but as soon as he saw Dristy struggling in the water he dove out and swam to his aid. But by the time he reached him, Dristy had gone under a couple of times in a panicky struggle, and Goldstein had a difficult time handling him, almost being drawn under himself.. Although a good swimmer, he was of much smaller build them Dristy. But he pluckily hung on until the other motorboat swung around and came up to aid them. By that time. Goldstein was almost exhausted, so that when the rescuers reached out from the boat and tried to yank him in first, the unconscious form slipped from his tired fingers and sank like a rock.
