Writes Jake Moore....
Shaun Jeffers put the visitors ahead on 13 minutes, converting a penalty, before the Clarets conceded one themselves, which allowed captain Josh McQuoid to restart the comeback.
McQuoid then added a second penalty after half-time, before adding to the scoreline from open play, before Ben Thompson got in on the rout to complete the scoring.
Weymouth won the first chance of the game through a free-kick in a dangerous position. Callum Buckley curled effort went just wide of the post without troubling Carl Pentney.
Chelmsford started the game strongly themselves through goalscorer Jeffers, who’s header fell narrowly wide after connecting with a Jordan Gibbons cross on five minutes.
Mickey Spillane won the Clarets a penalty on 12 minutes, which Jeffers concerted past Weymouth goalkeeper, Callum Ward.
The hosts didn't let their heads drop and had a few penalty shouts of their own waved away by the referee.
Weymouth came close to equalising after 20 minutes as Ben Thomson headed wide from Yemi Odubade's teasing cross.
Weymouth won themselves a penalty five minutes before the interval when midfielder Yemi Odubade fell to ground following pressure from Clarets defenders, Frazer Shaw and Jarvis Edobor. Captain McQuoid then sent Carl Pentney the wrong way to equalise.
Jordan Gibbons then came close to restoring the lead just two minutes later, but his strike whistled just past the post.
The first notable action of the second half came on 51 minutes when the referee pointed to the spot for a second time for the hosts. Jordan Ngalo was adjudged to have been fouled by Mickey Spillane through an outstretched leg, before McQuoid dispatched for the second time of the afternoon to give Weymouth the lead.
Chez Isaac came close to equalising a few minutes later but his low strike was claimed easily by Ward.
Weymouth then doubled their lead a minute later through McQuoid following a defensive mix-up. The Terras forward finished past Pentney to get his, and Weymouth’s third of the afternoon.
Alex Osborn came close to getting a goal back for the Clarets with their only notable chance of the second half, however the midfielder’s effort was blocked and cleared off the line to keep the score at 3-1.
This was only the case for the following 15 minutes however, as Ben Thomson managed to get hold of the ball and finish beyond Pentney to increase the hosts advantage.
Weymouth ensured all three points stayed on the south cost, handing the Clarets a second successive defeat, and certainly a day to forget.
