Matching a tunnel SeaArk 1652MVT 2010 against a modified vee SeaArk Forecast 170C 2010 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 1652MVT 2010 at 16,0 ft versus SeaArk Forecast 170C 2010 at 17,0 ft. Weight tells a clearer story for trailering families: the SeaArk Forecast 170C 2010 tips the scales at 775 lbs — 430 lbs less than the SeaArk 1652MVT 2010 at 345 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 Forecast 170C 2010 has a 30-hp advantage over the SeaArk 1652MVT 2010'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 1652MVT 2010 is rated for 6 passengers, while the SeaArk Forecast 170C 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 1652MVT 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk 1652MVT 2010 comes in at 8 lbs per hp versus 10 lbs per hp for the SeaArk Forecast 170C 2010. 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 1652MVT 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 Forecast 170C 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
