Matching a tunnel SeaArk 1872MVJT 2011 against a modified vee SeaArk DXS 1548 SLD 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — SeaArk 1872MVJT 2011 at 18,0 ft versus SeaArk DXS 1548 SLD 2012 at 15,0 ft. Weight tells a clearer story for trailering families: the SeaArk DXS 1548 SLD 2012 tips the scales at 355 lbs — 280 lbs less than the SeaArk 1872MVJT 2011 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 80 hp, the SeaArk 1872MVJT 2011 has a 50-hp advantage over the SeaArk DXS 1548 SLD 2012's 30-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 1872MVJT 2011 is rated for 11 passengers, while the SeaArk DXS 1548 SLD 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 1872MVJT 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk 1872MVJT 2011 comes in at 1 lbs per hp versus 12 lbs per hp for the SeaArk DXS 1548 SLD 2012. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the SeaArk 1872MVJT 2011 if your priority is putting more people on the water — it handles 11 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The SeaArk DXS 1548 SLD 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
