Online ship intelligence and information service VesselValue.com has launched a series highlighting the world's most expensive active vessels, and this week focuses on the costliest of all: QMAX liquefied natural gas (LNG) carrier Zarga, which prices in at a whopping $221.8 million. According to VesselValue, Zarga’s sticker price is equal to 1.5 of Real Madrid footballer Gareth Bale’s $145 million transfer fee, 13 12-carat Pink Diamonds at a value of $17 million each, or 49 Lamborghini Veneno Roadsters which cost $4.5 million apiece.
