Launched in 2012, Abbracci (ex-Serenity) was the largest displacement yacht launched by Heesen at the time. She was designed by Omega Architects with efficient naval architecture created by Heesen's in-house team in collaboration with Van Oossanen and Associates. Abbracci's layout accommodates 12 guests in a full-beam master suite on the main deck, which has two large side balconies, a full-beam VIP cabin, two doubles and two twins on the lower deck. Among the yacht's other special features is an enclosed spa area complete with steam bath, sauna and massage room.
