Navigator Yachts 56 Classic 2006 vs Navigator Yachts Navigator 58 Rival 2011 — Same Brand, Different Boat

The Navigator Yachts 56 Classic 2006 vs Navigator Yachts Navigator 58 Rival 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Navigator Yachts 56 Classic 2006 at 56,0 ft versus Navigator Yachts Navigator 58 Rival 2011 at 57,8 ft. Weight tells a clearer story for trailering families: the Navigator Yachts 56 Classic 2006 tips the scales at 455 lbs — 399 lbs more than the Navigator Yachts Navigator 58 Rival 2011 at 56 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Navigator Yachts Navigator 58 Rival 2011 tops out at 500 hp. Engine specs for the Navigator Yachts 56 Classic 2006 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Navigator Yachts Navigator 58 Rival 2011 carries 75 gallons versus 6 gallons in the Navigator Yachts 56 Classic 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 17 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.

Bottom line: The Navigator Yachts 56 Classic 2006 and Navigator Yachts Navigator 58 Rival 2011 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
