The deck and coach roof are designed to minimise wind resistance whilst ensuring that movement around and out of the cockpit is safe and easy. Bevelled edges throughout ensure that the lines are both attractive and functional and efficiency is emphasized by the high freeboard giving a drier ride for crew and helm. This is achieved without compromising locker space on deck or the space below. The importance of obtaining fair lines on deck has been the guiding line for the design team who have designed a functional, ergonomically efficient and safe deck suitable for both race crews and family sailors.

Externally, Bellissima differs from Fuoriserie for the twin wheels, the cockpit benches in synthetic teak and the integrated bowsprit.

The IY 9.98 is also suitable for long cruises, complementing the exciting sailing performance with a refined, carefully crafted and welcoming interior. Both versions have two cabins – one forward and one aft, an aft head, open plan central saloon, a galley and a comfortable navigation station. The modern look below is light, bright and airy characterized by a polished gelcoat finish giving surfaces that are attractive yet functional for racing. Innovative fabric lockers are removable to minimise displacement in race mode. An attractive antislip coating is bonded to the marine plywood cabin floors. All cabin doors have aluminium frames for greater durability. The chart table on the starboard side is opposite the galley equipped with a sink, generous fridge and a gimballed 2 burner stove.
