#33: HELIOS—189'3"

Fitting for a yacht bearing the name of the sun god, there's a spacious sundeck onboard and a fold-down section of the transom that transforms into the ultimate beach deck. She spent time in Australia last fall getting a new helipad installed. The yacht charters for up to $395,000 per week.
