In a nutshell? A heap of all that a rubber boat can be. It isn’t a boat with large fenders fixed on the sides, it doesn’t want only to astonish and show off, it isn’t conceived only for high speed. It is a pneumatic boat.
Capelli has accustomed us to high standards and everything seems predictable. But, by inspecting 755 Tempest, it is clear that it can be successful on an increasingly competitive market thanks to its strenghts: on one hand, functionality ( no special effects but everything is in the right place), with a perfect circulation on board, proper free spaces on the console’s sides, well-arranged manropes, small astern gangways to reach the dash board; on the other hand, high quality details and finishings 
(especially in consideration of the package price): so, beautiful lockers, excellent fabrics, 26 big equipments.
The rubber boat has a perfect interaction between hull and tubes; consequently a good static and dynamic gear and an excellent stability. In addition to a 42-knot-maximum speed we want to highlight the precise trajectories, the soft hull and the excellent stability, even at high speed.
The F225 FETX engine used during our sea trial belongs to the large Japanese family of six cylinders, from 200 to 250 HP. It is always the same monobloc, a fourstroke 4,2-liter- V6, with 24 valves (EFI electronic injection), Drive by Wire accelerator and gear. Fast cruising speed is 35 knots (61 l/h) while medium speed is 27 knots (39 l/h). Japanese propellers are excellent in terms of consumption.
As usual, Capelli-Yamaha collaboration offers interesting final prices and a good quality/price ratio. Tempest 775, with its 225 Yamaha, costs less more than 63,000 Euros (VAT included). If you prefer a 250 HP engine, the cost increase of 1,000 Euros.
