When two boats share the same hull type — in this case both the Lund 1900 Pro-V 2005 and the Lund 2150 Baron Gran Sport 2006 are modified vee designs with aluminum 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 — Lund 1900 Pro-V 2005 at 19,0 ft versus Lund 2150 Baron Gran Sport 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Lund 2150 Baron Gran Sport 2006 tips the scales at 2 255 lbs — 370 lbs less than the Lund 1900 Pro-V 2005 at 1 885 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 power gap is worth calling out. Rated to 250 hp, the Lund 2150 Baron Gran Sport 2006 has a 25-hp advantage over the Lund 1900 Pro-V 2005's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lund 2150 Baron Gran Sport 2006 carries 78 gallons versus 45 gallons in the Lund 1900 Pro-V 2005. 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 Lund 1900 Pro-V 2005 is rated for 6 passengers, while the Lund 2150 Baron Gran Sport 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1900 Pro-V 2005 could be the deciding factor.
Bottom line: Choose the Lund 1900 Pro-V 2005 if your priority is putting more people on the water — it handles 6 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Lund 2150 Baron Gran Sport 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
