Matching a tunnel SeaArk 2072MVT 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.
Size is the most obvious dividing line here. The SeaArk 2072MVT 2010 measures 20,1 feet overall (2010), giving it roughly 3,1 additional feet of deck space compared to the SeaArk Forecast 170C 2010 at 17,0 feet (2010). Weight tells a clearer story for trailering families: the SeaArk Forecast 170C 2010 tips the scales at 775 lbs — 694 lbs less than the SeaArk 2072MVT 2010 at 81 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.
Both boats share a closely matched power ceiling — 90 hp for the SeaArk 2072MVT 2010 and 75 hp for the SeaArk Forecast 170C 2010. 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 2072MVT 2010 is rated for 13 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 2072MVT 2010 could be the deciding factor.
Bottom line: Choose the SeaArk 2072MVT 2010 if your priority is putting more people on the water — it handles 13 passengers and at 20,1 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.
