When two boats share the same hull type — in this case both the Lund 1800 Explorer 2005 and the Lund 2150 Baron 2012 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?
Size is the most obvious dividing line here. The Lund 2150 Baron 2012 measures 21,8 feet overall (2012), giving it roughly 3,8 additional feet of deck space compared to the Lund 1800 Explorer 2005 at 18,0 feet (2005). Weight tells a clearer story for trailering families: the Lund 1800 Explorer 2005 tips the scales at 124 lbs — 103 lbs more than the Lund 2150 Baron 2012 at 21 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 300 hp, the Lund 2150 Baron 2012 has a 150-hp advantage over the Lund 1800 Explorer 2005's 150-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 2012 carries 78 gallons versus 32 gallons in the Lund 1800 Explorer 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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.
Bottom line: The Lund 2150 Baron 2012 at 21,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Lund 1800 Explorer 2005 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
