When two boats share the same hull type — in this case both the SeaArk 2072MVJT 2011 and the SeaArk BayRunner MVJT 2012 are tunnel 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?
On paper these two are close siblings in the size department — SeaArk 2072MVJT 2011 at 20,1 ft versus SeaArk BayRunner MVJT 2012 at 20,1 ft. At 81 lbs and 119 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.
The power gap is worth calling out. Rated to 115 hp, the SeaArk BayRunner MVJT 2012 has a 25-hp advantage over the SeaArk 2072MVJT 2011'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 2072MVJT 2011 is rated for 13 passengers, while the SeaArk BayRunner MVJT 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 2072MVJT 2011 could be the deciding factor.
Bottom line: Choose the SeaArk 2072MVJT 2011 if your priority is putting more people on the water — it handles 13 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk BayRunner MVJT 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
