Navigator Yachts Navigator 4600 2008 vs Navigator Yachts Navigator 5100 2012 — Same Brand, Different Boat

Matching a other Navigator Yachts Navigator 4600 2008 against a deep vee Navigator Yachts Navigator 5100 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Navigator Yachts Navigator 5100 2012 measures 51,7 feet overall (2012), giving it roughly 4,7 additional feet of deck space compared to the Navigator Yachts Navigator 4600 2008 at 47,0 feet (2008). At 4 lbs and 5 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 500 hp, the Navigator Yachts Navigator 5100 2012 has a 170-hp advantage over the Navigator Yachts Navigator 4600 2008's 330-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 6 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 5100 2012 is rated for 15 passengers, while the Navigator Yachts Navigator 4600 2008 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Navigator Yachts Navigator 5100 2012 could be the deciding factor.

Bottom line: Choose the Navigator Yachts Navigator 5100 2012 if your priority is putting more people on the water — it handles 15 passengers and at 51,7 ft it has the deck room to back that rating up comfortably. The Navigator Yachts Navigator 4600 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.

Which is the larger boat — the Navigator Yachts Navigator 4600 2008 or the Navigator Yachts Navigator 5100 2012?
The Navigator Yachts Navigator 5100 2012 is the longer of the two at 51,7 feet overall. The Navigator Yachts Navigator 4600 2008 comes in at 47,0 feet, making it roughly 4,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Navigator Yachts Navigator 4600 2008 or the Navigator Yachts Navigator 5100 2012?
For trailering, the Navigator Yachts Navigator 4600 2008 has the edge at 4 lbs dry weight versus 5 lbs for the Navigator Yachts Navigator 5100 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Navigator Yachts Navigator 5100 2012 is rated to a maximum of 500 hp, giving it the larger power ceiling. The Navigator Yachts Navigator 4600 2008 tops out at 330 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Navigator Yachts Navigator 4600 2008 is Coast Guard rated for 14 passengers, while the Navigator Yachts Navigator 5100 2012 is certified for 15. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Navigator Yachts Navigator 4600 2008 and Navigator Yachts Navigator 5100 2012 share an 15 ft beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Navigator Yachts Navigator 4600 2008 and Navigator Yachts Navigator 5100 2012?
Both boats carry similar fuel loads — 5 gallons and 6 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Navigator Yachts Navigator 4600 2008 and Navigator Yachts Navigator 5100 2012 from the same manufacturer?
Yes — both the Navigator Yachts Navigator 4600 2008 and the Navigator Yachts Navigator 5100 2012 are built by Navigator Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
