Matching a tunnel SeaArk 1660MVT 2010 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.
On paper these two are close siblings in the size department — SeaArk 1660MVT 2010 at 16,0 ft versus SeaArk Mud Runner 170 2013 at 16,8 ft. At 475 lbs and 475 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 — 50 hp for the SeaArk 1660MVT 2010 and 45 hp for the SeaArk Mud Runner 170 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 1660MVT 2010 is rated for 6 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 1660MVT 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk 1660MVT 2010 comes in at 10 lbs per hp versus 11 lbs per hp for the SeaArk Mud Runner 170 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the SeaArk 1660MVT 2010 if your priority is putting more people on the water — it handles 6 passengers and at 16,0 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.
