Gunboat 78

The Gunboat 78 is the maximum sized catamaran to fit the CE Class A ocean going yacht classification. Any larger, and yachts get weighted down with commercial style code regulations, and enormous crew requirements. The Gunboat 78 remains lightweight & practical, and delivers renowned Gunboat performance with her obvious luxury. Beautiful Italian interior styling by Nauta Yachts and impeccable fit and finish complete the yacht. A whisper of wind leads to acceleration you can feel. Her waterline enables smooth sailing without motion. The Gunboat 78 is a magical size that delivers all of the comfort of much larger yachts, without the headaches, expense and complication. Beyond this size requires a quantum jump in crew and crew space, without much increase in space dedicated to the owner and guests. The Gunboat 78 is a testament to experience, clear thinking and cleverness. She is for owners who love sailing, and understand exactly what they need from a large yacht without going to gauche proportions and expense.
