Even in a non-competitive atmosphere, Navy continued its domination of area rowing in yesterday's 10th Scullers' Head of the Potomac Regatta.

The high school and college seasons don't begin until fall, but this head racing event, which had teams start at 10-second intervals and row against the clock, gave teams a chance to compete against other schools for the first time.

The Midshipmen captured the men's open eight competition for the fourth straight year, completing the three-mile course -- which ran from two miles above Key Bridge to Roosevelt Bridge -- in 14 minutes 40.7 seconds. Navy's junior varsity finished just two seconds behind to earn second place.

"Any time we're put in a competetive situation . . . we want to win," Navy captain Alden Mills said, "even if we're racing the senior citizens masters."

The day's serene waters and soft breeze made conditions perfect and helped Navy's women, who won the open eights last year, complete a one-two sweep of the event this year.

The varsity club, which started next to last because it was late getting to the starting line, passed William and Mary and Navy's junior varsity club to finish in 16:49.

The Midshipmen also finished first in the men's open fours and men's open doubles, and the men and women teamed to capture the mixed eights.

Georgetown, whose program has made great strides in recent years, gave Navy some good competition, finishing third and fourth in the men's open eights. The Hoyas also tied for second in the novice quads and placed first in the youth men's fours and the speedy octuples, which has eight rowers with two oars apiece, and is unique to this regatta.

"We can learn a lot competing with a school like Navy," Hoyas Coach Tony Johnson said. "I don't have visions of beating them yet, but . . . "

Host Potomac Boat Club was the dominant club. Craig Losee won the men's intermediate singles, Bob Spousta captured the men's masters singles and Kevin Bedell took the men's lightweight singles. Elizabeth Weber won the women's senior masters singles.
