When two boats share the same hull type — in this case both the SeaArk 1872MV 2009 and the SeaArk Big Easy 2011 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 SeaArk Big Easy 2011 measures 24,0 feet overall (2011), giving it roughly 6,0 additional feet of deck space compared to the SeaArk 1872MV 2009 at 18,0 feet (2009). Weight tells a clearer story for trailering families: the SeaArk Big Easy 2011 tips the scales at 186 lbs — 111 lbs less than the SeaArk 1872MV 2009 at 75 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 225 hp, the SeaArk Big Easy 2011 has a 145-hp advantage over the SeaArk 1872MV 2009's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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.
Bottom line: The SeaArk Big Easy 2011 at 24,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The SeaArk 1872MV 2009 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.
