The vessel underwent several ownership changes over the years, taking on names such as Excalibur and Mayan Queen II before her current owner rechristened her as Hilarium. Diana Yacht design from Holland is the studio behind her naval architecture and design while Sue Wade is the designer of the yacht’s interior. In 2014, Halirium received her navy blue hull finish that today sets her apart from other Hakvoort yachts during a refit at the Derecktor yard in Florida. Here she is seen in downtown Boston by photographer Patrick Brusil.
