Georgetown, the host school, dominated the Cadle Cup Regatta at Thompson's Boat Center yesterday, winning six of the 11 events, including the men's varsity heavyweight eights.

The Hoyas unveiled a new rowing plan in easing to a six-second victory over rival George Washington and a near 10-second advantage over third-place Virginia.

GW got off to a good start as the teams began the race near Three Sisters Island below the Georgetown campus, but the Hoyas took the lead coming under Key Bridge, the halfway point in the race. Georgetown rowed smoothly for the final 1,000 meters and coasted in for the victory under the shadows of Watergate.

"We raced our own race. The idea was to sprint at the beginning, settle down and lengthen it out during the middle five-eighths of the race, and then sprint again at the end," said 118-pound coxswain Andy Kind of Georgetown, who was accorded the traditional victory dunking in the still chilly Potomac.

"They looked like a machine today," said Colonial coxswain Diane Godorov.

The Hoya varsity eight is working toward next weekend's Dad Vail championships in Philadelphia. Georgetown finished seventh among 56 schools in last year's Dad Vail, and this year the competition is expected to be just as intense.

"We're pretty happy as far as things went today," said Hoya Coach J.J. Forster. "I think we'll be right there in the thick of things at the Dad Vails. But it'll be tough."

Georgetown teams captured five other events yesterday: the women's novice fours, varsity fours and novice eights, and the men's freshman heavyweights and junior varsity heavyweight eights.

Bob Spousta of the Potomac Boating Club won the open single skulls over Mark Coulson of the same club. The two men were the only entrants.

In the women's varsity eight competition, Navy rolled to a convincing victory over Georgetown. Navy finished in 6:39 and the Hoyas were two lengths behind in 6:43. The Navy junior varsity eights also beat Georgetown.

At Annapolis, the Navy men's varsity heavyweight eight lost its first race of the season in the Adams Cup Regatta. Harvard outsprinted the Midshipmen in the final 400 yards to win by two seconds.
