The marketing is sleek. If the Gunboat 55 is as spacious as it looks in the video, I can see it having appeal to a large slice of the new boat buyer market. The shots and footage of it the NY harbor with the Manhattan skyline makes you realize you can be in an even better location (in fact you can be the view) than those background penthouses, for a lot less money. I could live on it for a bit.

And it looks like a pretty sleek Catamaran for the sailor as well but I don't have experience with sailing these boats(looks good in the vid, fast).

Selling the floating home any big yacht represents, this blurb below sums up the intelligent accommodation design angle. Realistic use for a boat like this.

"While many offerings in this size stuff a mansion’s worth of unused accommodations into the space, the GUNBOAT 55 shows ultimate restraint. There are simply two superyacht-style cabins, with the option of adding a third. Most people in this size range sail with their spouse and family, if a large group is onboard, the daybeds and sofas can handle the crowd."
