M/Y BACK 9 AND A HALF

Italian pedigree, 31-knot performance, and a 2024 refit.

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.

Interior & Accommodation

An owner's layout built for hosting ten guests.

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:

  • Owner's Stateroom: Forward on the main deck with full-beam dimensions, en-suite facilities, and private access
  • Two VIP Staterooms: Lower deck, each with en-suite bathroom and generous natural light
  • Two Twin Staterooms: Convertible to queens — flexibility for families or mixed parties, each with en-suite
  • Crew Quarters: 6 crew accommodated in separate quarters, ensuring service levels without compromising guest privacy
  • Galley: Fully equipped, designed for extended cruising and charter-standard operation
Exterior Highlights

Sport performance, sundeck living, shallow-water freedom.

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:

  • Sundeck: Full-beam upper deck with hot tub, bar, and multiple lounge areas — the social heart of the yacht
  • Aft Deck: Shaded dining and lounge space with direct connection to the main salon via curved sliding doors
  • Lower Deck & Beach Club: Waterline access for swimming, diving, and tender launches
  • Sport-Yacht Hull: Shallow 1.5m (4'11") draft opens the Bahamas, Caribbean, and remote anchorages unreachable to deeper-draft yachts
  • Water-Jet Propulsion: Three MTU engines with water jets for 31-knot top speed and reduced vibration at rest
