When two boats share the same hull type — in this case both the SeaArk 1872 Pro 2012 and the SeaArk 2472SS 2009 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 2472SS 2009 measures 24,0 feet overall (2009), giving it roughly 6,0 additional feet of deck space compared to the SeaArk 1872 Pro 2012 at 18,0 feet (2012). Weight tells a clearer story for trailering families: the SeaArk 1872 Pro 2012 tips the scales at 875 lbs — 794 lbs more than the SeaArk 2472SS 2009 at 81 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 130 hp, the SeaArk 1872 Pro 2012 has a 40-hp advantage over the SeaArk 2472SS 2009's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The SeaArk 2472SS 2009 is rated for 13 passengers, while the SeaArk 1872 Pro 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 2472SS 2009 could be the deciding factor.
Bottom line: Choose the SeaArk 2472SS 2009 if your priority is putting more people on the water — it handles 13 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The SeaArk 1872 Pro 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
