Delivered in 2017 as the 11th hull of the acclaimed ISA 120 Sport series, BACK 9 AND A HALF brings together Italian craftsmanship, proven sport-yacht performance, and a lifestyle-first approach to onboard living. Her sleek exterior, penned by Andrea Vallicelli, is paired with contemporary interiors by ISA Yachts and Guida Design — an atmosphere that feels both modern and immediately welcoming.
A comprehensive 2024 refit has brought every system and surface up to current standards, positioning her among the most turnkey yachts in her class. With three MTU engines delivering a 31-knot top end, zero-speed stabilization, and a 1.5m draft for shallow-water cruising, she is engineered for owners who want pace, versatility, and access to cruising grounds larger yachts simply cannot reach.
Critically, she is US Duty Paid — a significant financial advantage for American buyers — and qualifies as an IRS Bonus Depreciation candidate with commercial registration potential for charter revenue.







The main salon is bright and open, defined by large windows and curved sliding glass doors that create a seamless connection between interior and exterior. The atmosphere — contemporary, tactile, and unforced — sets the tone for the rest of the yacht.
Accommodation is arranged for up to 10 guests across 5 staterooms, with a dedicated owner's configuration that prioritises privacy and light:
BACK 9 AND A HALF is built for owners who cruise hard and entertain harder. Her exterior zones are each distinct, functional, and set up for immediate use:
