ISA Granturismo 33

Four pod drives instead of shafts is the detail that will matter most to whoever runs the ISA Granturismo 33 day to day: four Volvo Penta IPS 1350 units, 1,000 hp each, turning propellers that steer rather than a rudder behind a shaft. ISA is building her for a 2028 delivery, a 33-metre flybridge yacht engineered as much for the person driving her as for the guests aboard.

Build and provenance

ISA is developing her as part of its Granturismo line, with naval engineering by Palumbo Superyachts and the exterior and interior design by Enrico Gobbi's Team for Design, so the hull and the styling come from two separate specialist studios rather than one in-house team. The ISA Granturismo 33 measures 33 metres with a 7.5-metre beam and a 1.6-metre draft, and construction is under way in Italy for a 2028 delivery.

Layout and accommodation

Ten guests are accommodated across five cabins, with a crew of five to run the boat, a ratio that supports full service without the cabins competing with guest space for room. The bow is pushed forward and the superstructure is set back toward the stern, an arrangement that opens a long, uninterrupted run of deck aft of the bridge.

Performance and engineering

Four Volvo Penta IPS 1350 pod drives, each rated at 1,000 hp, give the ISA Granturismo 33 a 19.5-knot cruise and a 24-knot top speed. Pod drives place the propellers under the hull rather than behind a shaft, which is what lets a flybridge yacht of this size handle tightly at low speed as well as run fast in a straight line.

Where she lies and how to see her

The ISA Granturismo 33 is being built in Italy, on course for a 2028 delivery. We follow her build on a buyer's behalf, arrange a yard visit or sea trial once she is complete, and coordinate the survey that follows an accepted offer.
