Ridinger, founder and CEO of the structural sales company "Market America", commissioned the exterior and interior of the eleven metre wide "Utopia IV" from Enrico Gobbi. The Venetian designer created a Grand Sport Coupé on water that reflects the striking custom look of Rossinavi's "Aurora" and comes with a suitably equipped engine compartment. Four MTU diesels with a total output of 7756 kilowatts work on four waterjet units from Kamewa. They propel the aluminium hull, designed by Arrabito Naval Architects, to a maximum of 28 knots and enable a range of 3300 nautical miles at a cruising speed of twelve knots. Ridinger and his wife Loren are experienced yacht owners, having previously owned a 45-metre three-decker from Trinity Yachts, "Utopia III". On "Utopia IV", the entrepreneurial duo reside in the forward-facing owner's suite with a six-metre-wide terrace, while their ten guests are spread across six cabins. On the crew side, there is space for 13 people. With a draught of just 2.20 metres, "Utopia IV" can also anchor in shallow waters, such as off the Bahamas. With the bathing platform lowered and the tender garage open, the action then takes place aft in the spacious beach club and on up to three jet skis and a RIB.
