Matching a tunnel SeaArk BayFisher MVJT 2013 against a modified vee SeaArk Stealth 186 2009 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 BayFisher MVJT 2013 at 20,1 ft versus SeaArk Stealth 186 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the SeaArk BayFisher MVJT 2013 tips the scales at 119 lbs — 108 lbs more than the SeaArk Stealth 186 2009 at 11 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 140 hp, the SeaArk Stealth 186 2009 has a 25-hp advantage over the SeaArk BayFisher MVJT 2013's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the SeaArk Stealth 186 2009 carries 25 gallons versus 3 gallons in the SeaArk BayFisher MVJT 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The SeaArk BayFisher MVJT 2013 is rated for 6 passengers, while the SeaArk Stealth 186 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk BayFisher MVJT 2013 could be the deciding factor.
Bottom line: Choose the SeaArk BayFisher MVJT 2013 if your priority is putting more people on the water — it handles 6 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk Stealth 186 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
