Fitting neatly between the Riva 56 Rivale and the Riva 76 Bahamas – and marginally quicker than both – the new Riva 68 Diable is whatever you want it to be, from an uber-chic dayboat or weekender, to a super-luxury cruiser for six. The hardtop, with its sliding sunroof and powered bimini, makes the Diable superbly versatile for a variety of conditions.
