Matching a tunnel SeaArk Predator 200 AK 2012 against a modified vee SeaArk RiverCat 180 SC 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 Predator 200 AK 2012 at 20,5 ft versus SeaArk RiverCat 180 SC 2013 at 18,0 ft. Weight tells a clearer story for trailering families: the SeaArk RiverCat 180 SC 2013 tips the scales at 1 193 lbs — 1 048 lbs less than the SeaArk Predator 200 AK 2012 at 145 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 200 hp, the SeaArk Predator 200 AK 2012 has a 60-hp advantage over the SeaArk RiverCat 180 SC 2013's 140-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 4 gal and 3 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The SeaArk Predator 200 AK 2012 is rated for 6 passengers, while the SeaArk RiverCat 180 SC 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 Predator 200 AK 2012 could be the deciding factor.
Bottom line: Choose the SeaArk Predator 200 AK 2012 if your priority is putting more people on the water — it handles 6 passengers and at 20,5 ft it has the deck room to back that rating up comfortably. The SeaArk RiverCat 180 SC 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.
