The SeaArk 2072MVT 2007 vs SeaArk RXV 186 2013 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.
Size is the most obvious dividing line here. The SeaArk RXV 186 2013 measures 18,5 feet overall (2013), giving it roughly 16,5 additional feet of deck space compared to the SeaArk 2072MVT 2007 at 2,0 feet (2007). At 81 lbs and 9 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 90 hp for the SeaArk 2072MVT 2007 and 90 hp for the SeaArk RXV 186 2013. 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 2072MVT 2007 is rated for 13 passengers, while the SeaArk RXV 186 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 2072MVT 2007 could be the deciding factor.
Bottom line: Choose the SeaArk 2072MVT 2007 if your priority is putting more people on the water — it handles 13 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The SeaArk RXV 186 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
