Suspicious fire destroys Vic party boat A SUSPICIOUS fire has destroyed a party boat in Melbourne and caused $100,000 of damage. The 20-metre boat, moored at Banana Alley in Melbourne, was engulfed in flames on Tuesday at 2.30am (AEST). The boat, believed to be owned by Melbourne River Cruises, was completely destroyed in the blaze. MFB commander Brad Quinn says the fire is deemed to be suspicious because of its high fuel load and police are investigating. "It was well alight when crews arrived and started to sink below the water line," Mr Quinn said. Two other boats were threatened by fire but were saved. The MFB have set up pollution booms around the sunken vessel.
