A boat that was a great success, very aggressive and powerful with a 425-horsepower quad engine at the stern. We tried it at the end of the summer on our skin to tell you all the secrets of this roaring RIB.

It is already a reality in America, but here in Europe we have yet to see an inflatable boat with four 425-hp outboard engines. Capelli took care of that, proposing a boat where power and performance trump everything. The Tempest 50 – 15 meters in length, 4.20 in beam and a weight of 9,000 kg – is aimed at those who want to have a high-performance support vehicle that is comfortable and easy to operate even without a crew and … decidedly flashy. The four Yamaha XTOs, in fact, make this dinghy one of a kind: lots and lots of power in plain sight.


Electric steering, world’s first 4-stroke direct-injection engine with a significant benefit on torque and fuel consumption, very powerful alternator (42A at 1500 rpm), alternator cooling air outlet on the forward-direction grille (unusual position for an air outlet duct, but when the engine is up, during non-use, rainwater is prevented from entering), two standard water pumps (one made of metal to make volume, one made of neoprene to make pressure), possibility of changing the foot oil without having to wing the boat (in fact, by removing the grille, two “little tubes” are provided through which, by creating a vacuum with the help of a pump, the foot is emptied of the old oil to replace it, using the other little tube, with the new one). To those who were considering an upgrade from the “old” 350hp to the new 425hp XTO we can say that it is entirely feasible as the wheelbase and drilling jig are the same. The only possible problem is the approval of the boat

Tempest 50 design

Let’s move on to the boat. The layout of the Tempest 50, designed by Roberto Curtò, is intended to give the customer the privacy that an owner of boats of this size appreciates, even in a Day-Cruiser. In fact, the prototype we tested is proposed with two separate cabins, one in the bow and one amidships, to have maximum discretion on board even when accompanied by the crew.
