Pagarus the amphibious catamaran concept

Pagarus is the 25m, solar-powered, amphibious catamaran concept launched by Lazzarini Design Studio. The idea began life as a military vehicle, the name Pagarus originates from the Latin word for crab hence its shape. 

To reinforce the main body and stiffen the ride, a bridge steel structure connects each side to the other. The twin steel hulls can be configured with up to three bedrooms on each side. In total, Pagurus can accommodate up to eight passengers plus four crew . The yacht subdivides the living spaces in two side hulls, connected to each other through a bridge tower deck station. 

The vessel takes its power from both sun and water. In the immersed part of the yacht, the hulls are designed with a recess space that houses a 6.5-metre steel cylinder, each with a helical spiral flange like the thread of a screw. As the screw cylinders generate water friction, energy is made available to recharge the yacht batteries while sailing. The cylinders are connected to an independent engine and through “transfluid transmission” are able to move the yachts up to 5 knots and simultaneously generate energy. 

Non sail propulsion comes via stern driven dual propellers and twin 890hp diesel engines capable of moving the Pagarus to an estimated top speed of 24 knots. When the Pagarus reaches land it can increase its draft by lowering down the rotating cylinders to transform the catamaran into an amphibious vehicle, able to move on sand or mud terrains to speeds of up to 30kmh. 

Pagarus can be built to order from a starting price of €6.58m (£5.93m) for a carbon version with a twin-jet drive, which can reach 32 knots. Whilst it can also be built for a price of up to €24m  (£21.6m) for the amphibious “Crabmaran” version with reinforced steel.
