Inoui is Vitters' 33.4 metre lean, mean, green superyacht sailing machine. She was christened in 2013 and has been racing ever since.
Boat International went on board with Inoui's racing yacht owner Marco Vögele last year. He and his crew came second in Class A at the 2015 regatta and will be hoping to go one better this year.
The 46 metre Vitters sailing yacht Ganesha is the successor of the 38.9 metre yacht Ganesha I. She was launched in 2013 and has an impressive 62 metre Southern Spars carbon mast.
Ganesha won the 2014 World Superyacht Awards category for best sailing yacht over 40 metres.
She is primed for cruising and regatta racing, with her lines inspired by the beam-to-length ration and the low freeboard of the J Class yachts.
Ganesha raced in last year's event as well as coming second in June's 2015 Loro Piana Superyacht Regatta in Sardinia.
Ohana is a 50 metre flybridge sloop built by Fitzroy Yachts in New Zealand for a European owner.
Launched in 2012, she features naval architecture by Dubois Naval Architects and a huge beam of almost 10 metres. She has a distinctive grey and yellow hull and has been offered with a special charter rate in the Caribbean for the rest of the season.
Ohana can reach speeds of 18 knots under sail, making her a serious contender at previous Loro Piana Regattas. The crew will hope to put her speed to good use again at this year's event.
