Matching a tunnel SeaArk 1660MVT 2009 against a modified vee SeaArk Stealth 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 2009 at 16,0 ft versus SeaArk Stealth 170 2013 at 17,2 ft. Weight tells a clearer story for trailering families: the SeaArk 1660MVT 2009 tips the scales at 475 lbs — 332 lbs more than the SeaArk Stealth 170 2013 at 143 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 75 hp, the SeaArk Stealth 170 2013 has a 25-hp advantage over the SeaArk 1660MVT 2009's 50-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 1660MVT 2009 is rated for 6 passengers, while the SeaArk Stealth 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 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk Stealth 170 2013 comes in at 2 lbs per hp versus 10 lbs per hp for the SeaArk 1660MVT 2009. 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 2009 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 Stealth 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.
