SOUND INVESTMENT

Riva has striven over the years to reduce sound and vibration levels on all its yachts. At around 30 knots, the 68 Diable’s decibels just about everywhere rarely get above the mid80 range, about the same level of noise as a lawn mower. At a 10-knot chug, I measured 74 decibels at the helm and 70 to 72 decibels in the master stateroom. That’s the equivalent of a hair dryer or dishwasher.
