Matching a modified vee SeaArk BayFisher 2008 against a tunnel SeaArk BayRunner MVT 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.
Size is the most obvious dividing line here. The SeaArk BayRunner MVT 2012 measures 20,1 feet overall (2012), giving it roughly 18,1 additional feet of deck space compared to the SeaArk BayFisher 2008 at 2,0 feet (2008). At 113 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.
Both boats share a closely matched power ceiling — 140 hp for the SeaArk BayFisher 2008 and 140 hp for the SeaArk BayRunner MVT 2012. 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 BayFisher 2008 is rated for 12 passengers, while the SeaArk BayRunner MVT 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 BayFisher 2008 could be the deciding factor.
Bottom line: Choose the SeaArk BayFisher 2008 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The SeaArk BayRunner MVT 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.
