Fire fighters doused a derelict barge with water this week as a blaze ripped through the dangerous structure just off Denton Island in Newhaven.
The well known local eyesore caught fire accidentally during demolition work which was being carried out on Tuesday June 17 by Cannon Demolition.
The company said the owner had asked it to remove the boat so a new one could be put in its place.
Trevor Cutler from Newhaven Coastguard said: “It is an eyesore especially when they are trying to regenerate Newhaven and make it a nice place.
“It is a long time coming and it will tidy up the area.”
Trevor said he had been called to numerous incidents at the boat including injuries and even a death when someone fell overboard and drowned.
He explained it was a dangerous structure, rotten, with sharp edges and littered with hypodermic needles. It was also a magnet for rough sleepers.
East Sussex Fire and Rescue Service was called to the boat along with the Coastguard and Sussex Police at 9.26am.
The A259 was closed, causing delays. Heavy smoke was seen in the area.
Fire fighters extinguished the blaze. The demolition and removal of the boat should take another two to three weeks.
It is understood the blaze started when the wind changed direction while wood was being burned on board.
