When two boats share the same hull type — in this case both the Meridian Yachts 391 Sedan 2008 and the Meridian Yachts 408 Motoryacht 2008 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 408 Motoryacht 2008 measures 42,0 feet overall (2008), giving it roughly 38,0 additional feet of deck space compared to the Meridian Yachts 391 Sedan 2008 at 4,0 feet (2008). At 25 lbs and 29 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 425 hp, the Meridian Yachts 408 Motoryacht 2008 has a 417-hp advantage over the Meridian Yachts 391 Sedan 2008's 8-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 35 gal and 33 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 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.
