Best way to dispose of old boat?
Gas bomb!! But make sure you are well clear yourself and from other boats. It would require some sort of remote detonation device.
Any suggestions on what could do that job??
If the boat is insured to the hilt it could be a bonus.
A bloke did it many years ago on Auckland Harbour. He did it when there plenty of boats on the harbour to see it and by the way rescue him.
He sat on the transom with his back to the cabin and his fingers in his ears and I think he tossed a sparkler over his shoulder into the cabin when he could smell the gas from his position.
