A passing yacht called the Coastguard and reported a large net floating in the vicinity of the Mewstone. As it would be a hazard to other passing craft the inshore lifeboat was asked to investigate. The lifeboat was launched after the crew was assembled. A sector search was carried out using the last reported position of the sighting and also along the tideline. Despite communications with the yacht at the scene and the National Coastwatch station at Froward Point overlooking the area, a net was not found and the crew returned to station.
