A pickup crew of experienced Potomac Boat Club scullers overcame several faulty strokes, caught Georgetown University's Henley-bound eight and won the open eight finale of the President's Cup Regatta yesterday on the Potomac River.

The second of two Potomac entries, a crew that had not taken a stroke together before yesterday's races, finished the 2,000-meter course in 5:51.1. Georgetown was second in 5:58.2.

"Not bad at all," said Bob Spousta, who earlier had won the elite single and open single dashes.

"We had some problems early, caught a couple of crabs, but we seemed strong at the finish."

Overall, Potomac fared well in a regatta that this year doubled as the Mid-Atlantic Regional Championship of the U.S. Rowing and National Women's Rowing associations. The club won nine of the 18 events.

Spousta, who coaches at T.C. Williams High School, said that the conditions were too choppy and windy for scullers. "But scullers have to row in all conditions," he said after defeating Eric Meyers in the elite open single dash.

Danny Rutenberg of Undine Boat Club in Philadelphia won twice, as did Potomac members Richard Schmitt, Simon Williams and coxswain Elizabeth Zipf.
