As announced a few weeks back Riviera is offering new IPS propulsion option to the 51 model, but this is not only available to the Open Flybridge but also to the Enclosed Flybridge Series II. Following extensive testing, the Enclosed Bridge version of the 51 is now available with triple Volvo Penta IPS drive systems. The same 51 Enclosed Flybridge Series will continue to be offered with shaft drive. With more than 150 of Riviera 51 Flybridge delivered this classy three cabin Sportfish Yacht, now has the option of Volvo innovative front looking IPS pod drives offering additional space amidships. Standard engine room area is now used for storage, stowing diving, fishing gear, and an optional crew’s quarters including bunk and a fully-equipped bathroom. Access to the space is via a door from the cockpit but there is also an option to provide a second access via a hatch in the saloon. This space also includes the boat’s gen set, air conditioning units and battery banks, offering very easy servicing. It is also used to access the front of the three Volvo Penta IPS engines. Main access to the engines is via the hinged cockpit floor that lifts on an electric actuator. The fuel tank is forward, immediately behind the accommodation bulkhead, offering noise protection to the accommodation area. The IPS propelled option features an entirely new hull, developed by Riviera’s design team in consultation with Volvo Penta senior designers. Dead rise at the transom is now 15 degrees. The new propulsion option builds on the features of the Riviera 51 Enclosed Flybridge Series II model launched at the 2008 Sydney International Boat Show.
