#42: ALTITUDE—180'4"

For couples who like to cruise together yet want a bit more privacy than the typical "all guest staterooms on the lower deck" layout, here's a yacht with an interesting solution. She places an extra guest stateroom steps away from the skylounge. This is in addition to the split-level master suite on the main deck and four traditional guest staterooms below. Her high-season rate for the Caribbean this winter is $259,000 per week.
