Other things make Arianna stand out, too. For one, the decor follows a Polynesian theme. The owners are working with the Delta Design Group, Delta Marine's in-house team, to set the scene. It will be executed with a combination of Macassar ebony, wenge, and koa wood paneling, among other things. Another highlight inside is a room for kids within the owner's suite, located on the upper deck. For grown-ups, there's a sauna within the gym—and it's in an unusual location, forward on the main deck. Also unusual is a float-in tender garage.
