Unlike its more classically shaped siblings, the Custom Line 100 (+39.0543.787511, www.customline-yacht.com), the first of which the Ferretti Group unveiled last July, features a sporty design with a voluminous, wide-body shape. The 100-foot yacht’s standout features include a fold-down balcony off the main-deck salon, plentiful windows, and strategically placed LED lighting that further brightens the interior. The forward main-deck master suite and four lower-deck staterooms all have large windows and en-suite bathrooms. Powered by twin MTU 16V 2000 M94 engines, the Custom Line 100, a planing-hull design, reaches a maximum speed of 27 knots. A Mitsubishi Anti-Rolling Gyro stabilization system helps steady the yacht. The exterior offers sunning, dining, and lounging spaces, as well as a grill and a bar. The Custom Line 100 is a highly customizable design; the owner of hull number one chose wide-planked wood floors finished in a gray varnish, leather paneling throughout the interior, and neutral-toned fabrics.
