Super yachts are 24 meters or over in length. This was about a 5 million pound boat. Insurance fraud for yachts is nearly unheard of, except in the comments section of YouTube. The last time someone had this happen, it was due to an electrical short (220 volts) in the galley. Last fatality I recall was a 440 volt unearthed fault in the engine room. Electricity is dangerous. Glass Reinforced Plastic is deadly when it burns.
