When two boats share the same hull type — in this case both the Meridian Yachts 391 Sedan 2009 and the Meridian Yachts 459 Motoryacht 2009 are modified 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?

Size is the most obvious dividing line here. The Meridian Yachts 459 Motoryacht 2009 measures 47,0 feet overall (2009), giving it roughly 7,0 additional feet of deck space compared to the Meridian Yachts 391 Sedan 2009 at 40,0 feet (2009). Weight tells a clearer story for trailering families: the Meridian Yachts 459 Motoryacht 2009 tips the scales at 30 700 lbs — 5 700 lbs less than the Meridian Yachts 391 Sedan 2009 at 25 000 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.

Both boats share a closely matched power ceiling — 8 hp for the Meridian Yachts 391 Sedan 2009 and 8 hp for the Meridian Yachts 459 Motoryacht 2009. 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 Meridian Yachts 391 Sedan 2009 carries 350 gallons versus 330 gallons in the Meridian Yachts 459 Motoryacht 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Meridian Yachts 459 Motoryacht 2009 is rated for 14 passengers, while the Meridian Yachts 391 Sedan 2009 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Meridian Yachts 459 Motoryacht 2009 could be the deciding factor.
