Much as I loved the quiet operation of this boat, an even bigger comfort boost comes in the cabin. And no, I'm not just talking about the full galley with a dishware rack, Amtico sole, and under-counter refrigerator, freezer, and microwave/convection oven. Nor am I talking about the washer/dryer, a feature commonly found on larger boats, built into the companionway. I'm not even talking about the leather settee, liquor cabinet with icemaker, electric-opening overhead rodbox, or dedicated midship machinery room, which boosts the accessibility of the air conditioning handlers, water heater, shower sump, battery chargers, and freshwater manifolds. So I must be referring to the three-stateroom layout, which provides privacy for six, unusual in a boat of this size? Nope. The coolest comfort booster on Riviera's 45 Flybridge is the massive aft salon window -- because the entire thing is hinged and secured with huge stainless-steel dogs. Swing it open, let the ocean breezes flow, and enjoy the great outdoors from the indoors.
