MERCURY measures 50 metres, hosting twelve guests across five cabins with a crew of twelve. A 2001 yacht chartering from Monaco, she has the proportions of a proper superyacht and decades of seasons under her keel. The Riviera lies on her doorstep — Cannes and the Îles de Lérins one way, the Estérel and Saint-Tropez the other. From €170,000 a week.
