When two boats share the same hull type — in this case both the Navigator Yachts Navigator 5500 2013 and the Navigator Yachts Navigator 58 Rival 2010 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 — Navigator Yachts Navigator 5500 2013 at 55,7 ft versus Navigator Yachts Navigator 58 Rival 2010 at 57,8 ft. At 54 lbs and 56 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.
The power gap is worth calling out. Rated to 530 hp, the Navigator Yachts Navigator 5500 2013 has a 30-hp advantage over the Navigator Yachts Navigator 58 Rival 2010's 500-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 75 gal and 75 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Navigator Yachts Navigator 58 Rival 2010 is rated for 17 passengers, while the Navigator Yachts Navigator 5500 2013 caps at 16. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Navigator Yachts Navigator 58 Rival 2010 could be the deciding factor.
Bottom line: Choose the Navigator Yachts Navigator 58 Rival 2010 if your priority is putting more people on the water — it handles 17 passengers and at 57,8 ft it has the deck room to back that rating up comfortably. The Navigator Yachts Navigator 5500 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 16 that costs less to run day-to-day.
