Tortoise, a 115-foot, eco-friendly superyacht built in 2015 by Arcadia Yachts, is essentially a fiberglass floating fortress—and it is currently available for charter in the Mediterranean. For about $112,000 per week, plus expenses, guests can escape the winter blues and find solace aboard with its contemporary interiors lavishly designed by the renowned Italian firm Poltrona Frau, known for its decadent leathers.

Dressed in an ocean-like turquoise-and-white motif, the yacht also brings the outdoors in, through floor-to-ceiling windows that allow the sun to dance across the roomy interiors. Six cabins (each with a private veranda) are broken down to a master suite, two twin cabins, and three double cabins, accommodating up to 12 guests. The gym, television room, and deck Jacuzzi are all popular hideaways. Guests also can choose to play in the water with a plethora of adrenaline-producing toys, including a WaveRunner, wakeboard, and water skis.
