The SeaArk 1652MVJT 2006 vs SeaArk 1860MV 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — SeaArk 1652MVJT 2006 at 16,0 ft versus SeaArk 1860MV 2011 at 18,0 ft. Weight tells a clearer story for trailering families: the SeaArk 1652MVJT 2006 tips the scales at 345 lbs — 340 lbs more than the SeaArk 1860MV 2011 at 5 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.
Both boats share a closely matched power ceiling — 45 hp for the SeaArk 1652MVJT 2006 and 60 hp for the SeaArk 1860MV 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The SeaArk 1860MV 2011 is rated for 7 passengers, while the SeaArk 1652MVJT 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 1860MV 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk 1860MV 2011 comes in at 0 lbs per hp versus 8 lbs per hp for the SeaArk 1652MVJT 2006. 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 1860MV 2011 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The SeaArk 1652MVJT 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
