The Jongert 500 LE motor yacht is an exclusive superyacht measuring 50 meters in length. The new 50 Jongert LE 500 motor yacht was developed in cooperation with Azure Naval Architects and Guido de Groot and is characterized by Privacy, reliability, comfort and performance. The 500 LE yacht will feature an aluminium hull and superstructure.
The Jongert 500LE superyacht measures 50m in length with a gross tonnage of slightly less than 500 GT. The LE 500 yacht is equipped with a hybrid diesel electric propulsion system using Lithium-ion batteries. If desired the yacht can be equipped with fully wheelchair accessibility and/or a lift. One of the many special facilities on board is the telescopic anchor system. This system allows the yacht to be moored quickly and easily in any place up to 15 meters depth. The first two yachts will be built as a special “limited edition”.
The idea for the Jongert motor yacht was the outcome of discussions with customers about their dreams and wishes when it comes to the ideal motor yacht. ‘Our design team, in cooperation with leading national and international yacht architects and designers, has translated these wishes into the designs we now present. We are very proud of the result.’ The fact that, in the meantime the first orders have been signed shows that the customers are also pleased with the new yachts.
The Jongert 500 LE motor yacht is expected to reach a maximum speed of 16 knots at half load with a Range of 6.200 Nm @ 10 knots. The yacht will be able to accommodate up to 10 guests and 10 crew members.
The Jongert 500 LE motor yacht features Naval Architecture by Azure Naval Architects and Interior and Exterior styling by Guido de Groot and is to be built at the Jongert Shipyard. The first motor yacht of the Jongert 500LE motor yacht series will be built under the hull number Bn433 and is expected to be launched in 2013.
