A disabled man drowned after strapping himself into his motorised wheelchair and driving off a harbour wall, an inquest has been told.
Murdo Macleod Mackenzie, 74, was seen feeding seagulls at Poole Quay in Dorset just moments before he appeared to steer the machine towards the water.
The retired electrical engineer plunged over the edge of the quayside wall and sank 15ft to the bottom in front of shocked bystanders.
The crew of a moored-up pleasure boat used a grapple hook in attempts to save him, as emergency services rushed to the scene on Tuesday last week at about 1.10pm.
They recovered Mr Mackenzies body after about 20 minutes and he was pronounced dead at the scene.

The RNLI were called on Tuesday last week and helped in rescue efforts at Poole Quay
A woman who works in a quayside shop said following the death: We think it was an elderly man who had lost a leg late in life and was struggling with it.
Its just extremely sad. The emergency services were here very quickly.
When they got here there were still people filming and there were officers shouting at them to stop.
A local resident said: My dad was having a drink in a pub there and he rang me to say that they had seen a man in a wheelchair with one leg.
He was seen going at speed straight over the edge. He was strapped to his wheelchair so they couldnt get him out. He was under the water for some time before anybody got to him.
I just feel sorry for his family and for him.
A spokesperson for Dorset Police said officers had responded to reports of a concern for the welfare of the man in the water.
