Viper 100 #01

Four cabins for eight guests, with a crew of four to match, points to a boat built more for day speed than for long stays aboard. ISA is building hull number one of the Viper 100 #01 at its yard in Ancona, a 31 metre sports yacht due in 2027.

Build and provenance

She is hull number one of ISA's Viper 100, moulded in GRP with a GRP superstructure for a sports yacht shaped for speed rather than for carrying weight. At 230 gross tons across 31 metres, the GRP construction keeps the weight down for the speed the hull is meant to reach.

Layout and accommodation

Eight guests sleep across the Viper 100's four cabins, with a crew of four aboard to run her, a crew count close to guest count that suits short, fast outings rather than long stays aboard. The beach club at the stern opens onto the water at anchor.

Performance and engineering

She is built to cruise at 38 knots, the kind of pace that puts her hull on the plane and marks her as a sports yacht rather than a cruiser with sporting lines. Zero speed stabilisers hold her steady at rest, useful once she is off the plane and sitting at anchor.

On deck and at anchor

The beach club opens at the stern, and a swimming pool doubles as a deck jacuzzi for time in the water without leaving the boat. A gym is fitted for guests who want to keep to routine, and a jet ski is carried.

Where she lies and how to see her

Ancona, Italy, is where the Viper 100 #01 is taking shape, and Boatcrowd is arranging viewings there. Once an offer is accepted, survey and sea trial follow before handover.
