Matching a modified vee SeaArk BayFisher 2011 against a flat SeaArk Mud Runner 170 2013 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 BayFisher 2011 measures 20,1 feet overall (2011), giving it roughly 3,3 additional feet of deck space compared to the SeaArk Mud Runner 170 2013 at 16,8 feet (2013). Weight tells a clearer story for trailering families: the SeaArk Mud Runner 170 2013 tips the scales at 475 lbs — 356 lbs less than the SeaArk BayFisher 2011 at 119 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 BayFisher 2011 has a 95-hp advantage over the SeaArk Mud Runner 170 2013's 45-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 BayFisher 2011 is rated for 12 passengers, while the SeaArk Mud Runner 170 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 BayFisher 2011 could be the deciding factor.
Bottom line: Choose the SeaArk BayFisher 2011 if your priority is putting more people on the water — it handles 12 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk Mud Runner 170 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.
