Tempest 44, pure emotion

A super R.I.B. built by Cantieri Capelli and marketed by Yamaha Motor Italia, which we tested with a triple engine for a total of 900 hp. A strong emotion to be experienced safely with outstanding comfort on board

WHAT SORT OF FEELING DO YOU THINK YOU’D GET CLIMBING ABOARD A HUGE INFLATABLE BOAT WITH THREE OUTBOARD ENGINES OF 300 HORSEPOWER EACH TOTALLING 900 HORSEPOWER AT THE AFT? Well, I can tell you that even for someone like me who does this sort of thing for a job, it is very exciting. Particularly when the engines are turned on and even more when everything “sings” together. This is my experience of testing the Capelli Tempest 44 in the water at the Yamaha European Meeting in the Netherlands. The boat is a R.I.B. (Rigid Inflatable Boat) produced by the Capelli boat yard in the RIBS Division, though commercialised in Italy by Yamaha Motor Italia. Two engine solutions are available: three outboard 300 horsepower engines, as I tried, or alternatively, three F350s, raising the maximum power to some 1,050 horsepower. “But isn’t that too much?” some might ask. Well no, because the Tempest 44 is not just a very large inflatable boat, but it also weighs a hefty 6 tonnes without its engines and therefore needs high horsepower. Whoever chooses this boat is obviously looking for the “best” and what better way to stand out from the crowd than with an extraordinary inflatable boat and three engines at the aft?

Right, the appropriate introductions over, let’s talk about the Tempest 44 which is the flagship of the boat yard run by Umberto Capelli. To all extents and purposes a Walk Around, the inflatable boat has a cabin at the bow under the deck. It can be topped with cushions to obtain a generous sundeck, well protected by robust steel handrails culminating in a bow delfiniera/ladder. As traditional for WAs, the cockpit can be accessed by two corridors flanking the captain area and going down a few steps. The console is central but it shares the instrumental area in part with the door to the cabin. The smoked windscreen has steel mouldings that end in handles for holding while navigating. The captain and co-captain seats are well-filled armchairs complete with back and arm rests. The front part of the cushions can be removed. The cockpit is vast and has been designed for total comfort when the boat is both stationary and moving.

It has been entirely cladded with teak and features two wooden flip-up tables, a large sofa in the beam, two lockers just behind the captain’s chair which are topped with cushions to sit on and, in the area behind the captain and co-captain’s chairs, a kitchen area including a sink, two hobs, fridge, various cupboards and side glass rack. Topping everything off, there is a large circa 5m2 sundeck in the aft. What was originally an “engine room” is here a storage locker, whose cover can be lifted electronically. The area can be shaded from the sun with an awning that disappears in the fibreglass structure of the hull. The engines are bolted, the ladder is fixed and there are four fenderholds in the hull. While by day you can enjoy the boat’s extensive outdoor space, by night you can count on comfortable, elegant and functional spaces. There is a sophisticated dinette in the bow offering a classical bivalent table solution to make a bed sleeping two into a double. A second sleeping area for guests is in the aft under the access ladder, and offers a bed and a half and shelves along the side to place personal belongings. There is also a separate bathroom area, including a marine toilet, shower, chocolate coloured sink and tasteful fittings. The Luxury Pack offers clients the option to add air conditioning and leather cushions. Meanwhile the series version is cladded with dark grey wood.

The test
The deep V of the hull provides superb behaviour in the water even when there are waves. The test inflatable boat does not have the maximum power available, but even with 150 less horsepower there is no lack of adrenaline. That’s because on board the Tempest 44 you don’t feel the speed as the weight of the boat and the engines soften any impact with the water surface. The fact is we reached 48 knots with 6,000 revs practically without realising it, apart from the tears in our eyes caused by the air and speed. The three 300 horsepower outboards are ready, reactive and have been equipped with Saltwater Series II SDS propellers with 19” pitch. When changing direction there is no hint of losing adherence or control and the boat is easy to manoeuvre; captains don’t need to be “veterans”. The boat planes in about five seconds and maintains it at the minimum value of 15/16 knots, which is not insignificant given the tonnage at around 3,000/3,200 rpm. A good cruising speed can be considered to be 32 knots at 4,500 revs, a performance recording a total consumption of 200 litres per hour (for the three engines). With these engines, 1,000 litres in the tank is not a lot and balancing performance and consumption the autonomy is at about 150/160 miles.
