The MAIB has issued a safety bulletin after the capsize of a sailing boat on Windermere with the loss of one life on 12 June 2019. The bulletin contains details on the background of the accident, initial findings, action taken and a safety lesson.

At approximately 1220 on 12 June 2019, a RS Venture Connect sailing boat fully inverted, its crew comprised an assistant instructor and an experienced disabled crewman. The boat was knocked down in the windy conditions on the day and heeled to such an extent that the keel fully retracted. During the subsequent capsize, the disabled crewman became trapped under the inverted boat. The safety boat crew saw the accident and attended the scene quickly, but had difficulty righting the boat and so were unable to reach the crewman in sufficient time to effect a successful rescue.

It was found that the retractable keel restraining VelcroTM strap was not fitted, allowing the keel to move freely in its housing.

Safety lesson
To prevent a similar accident, owners and operators of boats with retractable keels or retractable weighted centreboards, regardless of make or model, are recommended to ensure that:

– prior to use, checks should be made to ensure the manufacturer’s instructions regarding the securing of the keel or centerboard have been followed;
– their procedures and drills for recovering a capsized boat include the scenario where the keel or centreboard has retracted from its ‘lowered’ position
