A Perth plumber has built an epic 'floating bar' that can hold six adults and a full esky of beer, perfect for hot days on the water. The boat, appropriately named 'Bottoms Up', was created for Australia Day festivities to provide one man and his group of mates the perfect opportunity to sink some cans while relaxing in the sun. Mark Quattrini told PerthNow the group christened the vessel on Tuesday to enjoy some well-earned beverages. Doesn't get much better: The friends enjoyed their well earned drinks aboard the 'floating bar' on a sand bar at South Fremantle 'It was a great Australia Day, we spent it on the sand bar there at South Fremantle and had a few drinks and that. It worked really well, it was great.'
