When two boats share the same hull type — in this case both the Riviera Yachts 58 Enclosed Flybridge 2012 and the Riviera Yachts 63 Enclosed Flybridge 2012 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Riviera Yachts 58 Enclosed Flybridge 2012 at 63,3 ft versus Riviera Yachts 63 Enclosed Flybridge 2012 at 64,4 ft. At 661 lbs and 672 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 1 015 hp for the Riviera Yachts 58 Enclosed Flybridge 2012 and 1 015 hp for the Riviera Yachts 63 Enclosed Flybridge 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Riviera Yachts 63 Enclosed Flybridge 2012 carries 1 731 gallons versus 1 506 gallons in the Riviera Yachts 58 Enclosed Flybridge 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 18 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
