A grid search of the area failed to find anything and the search was later called off.

In the Serpentine River last weekend a 6.3m vessel with three people on board had mechanical problems and had to be towed to the Mary Street jetty.

On a separate incident, four people on board a 5.1m vessel ran out of fuel between the Mandurah Estuary Bridge and the Old Mandurah Bridge.

Mandurah Water Rescue group is still looking for new people who want to join.
