The partially keeled hull has been designed with twin massive steps, triple propeller tunnels and bulb.
The keel runs over two third of the hull length to increase stability at slow speed and in following seas.
The two steps play two roles, reducing the buoyancy aft to keep pitching movement to the minimum at displacement speeds and compensate the weight of the superstructure installed very much forward, while they will ventilate the propellers at higher speed.
The specific bulb design that has been studied at the Rome tank testing facility (Insean), increases the running surface at slow speed, thus reducing fuel consumption.
Above 20 knots, the bulb will partially be out of the water and will also help reducing pitching movements.
The three propellers tunnels where designed to reduce the draft of the yacht that will be limited to 2,10 metres at half load, opening extended shallow waters cruising grounds.
As a result, with these new engines, the Oceanic 140’ Fast Expedition will offer a range in excess of over 6000 nautical-miles at 10 knots while at 21 knots, she has an 800 nautical mile range and a top speed of 25 knots.
This superyacht will offer an aft deck of about 110 square meters, with aft Jacuzzi, sun pads, bar, dining room and day head with direct access to the tender bay for a 6-metre tender and plenty of toys located amidship. Underneath the tender bay will be installed a Veem® 145 SD gyroscope stabilisation system.
