That’s because another Beanpot trophy is headed to Weld Boathouse. The team added to its collection yesterday morning, impressively topping a five-school field on the Charles River.

In the featured varsity race, Radcliffe (the name used by Harvard women’s rowing) pulled clear of the competition shortly after the 1,000-meter mark and won with a time of 6 minutes 43.9 seconds. Northeastern was the closest pursuer, finishing in 6:52.0, while Boston University (6:59.7) held off a spirited MIT (7:02.4) for third. Boston College (7:19.6) was fifth.

“What I liked best about our effort was our poise and patience,’’ said Radcliffe coach Liz O’Leary, whose varsity won the Beanpot for the fourth time in the event’s five-year history. “Northeastern kept right with us early on, but we stayed with our race plan and showed great energy in the third 500 to take control.’’

The win comes on the heels of a victory over defending national champion Yale that lifted Radcliffe to third in the East. Northeastern, though, didn’t go away quietly.

“I told our crew that we had to be prepared to race [Radcliffe] right from the start,’’ said NU coach Joe Wilhelm. “We did that, but they were just stronger than us in the second half. We need to be able to hold our pace longer.’’

The second varsity and varsity four races also went Radcliffe’s way, helping it clinch the Beanpot team points banner for the fifth straight year.

However, the awards ceremony, scheduled for BU’s DeWolfe Boathouse, was canceled after a suspicious package was found in the area along Memorial Drive. Authorities also did not allow several rowers and coaches to come ashore. BU assistant director of athletic communications Scott Ellis described the package as being about a half-block from the boathouse and having a heavy amount of black tape on it.

“We knew right away the authorities were taking this seriously,’’ said Ellis.

Since a number of boats were still on the water and no one could approach or leave the boathouse, the presentation couldn’t take place.

Back on the water, the Harvard men got the best of Northeastern to win the Smith Cup for the 14th straight year. The Crimson, ranked first in the East and third nationally, wasted little time, gaining open water in the first 500 meters and cruising to a 4-length win, 5:56.7 to 6:11.4.

“The conditions allowed for good racing,’’ said Harvard coach Harry Parker. “We came out and set a fast pace, but even with us moving well, we couldn’t take anything for granted against a Northeastern crew that rows very hard.’’

Still, NU coach John Pojednic knows his varsity is struggling right now. “Our goal is to work on the things to help find the spark that’s eluded us this spring,’’ he said. “We’ll keep at it — part of it is getting the lineup right — so we can be competitive at Sprints. We need to do that so our team can qualify for IRAs.’’

Pojednic’s underlying motivation is to make sure his talented freshman boat has the opportunity to race beyond Sprints. Just a week ago, the NU freshmen defeated Brown for the first time in 31 years. Yesterday morning, they went toe to toe with Harvard — which hasn’t lost a dual race since 2006 — before being edged by 1.2 seconds.

The day’s most exciting contest came in men’s lightweight as second-ranked Harvard broke free of No. 1 Princeton and No. 4 Yale to win the Goldthwait Cup. The three boats were level through the first 1,000 meters before Harvard seized the upper hand.

“We had our best 30 or 40 strokes in that third 500 and got the space we needed,’’ said Harvard coach Charley Butt, whose crew finished the dual season 9-0. “Before and after that, the boats had equal speed. We just found a real good rhythm in that burst.’’

The Crimson were timed in 6:03.7, with Princeton (6:04.7) two seats behind. Yale (6:08.5) ended up 1 1/2 lengths off the pace.

In women’s lightweight action, fourth-ranked Radcliffe easily outpaced No. 7 MIT, 7:04.12 to 7:29.3.
