Matching a modified vee SeaArk Coastal 200 (SC) 2009 against a flat SeaArk Mud Runner 180 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.

Size is the most obvious dividing line here. The SeaArk Mud Runner 180 2013 measures 18,0 feet overall (2013), giving it roughly 16,0 additional feet of deck space compared to the SeaArk Coastal 200 (SC) 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the SeaArk Coastal 200 (SC) 2009 tips the scales at 119 lbs — 112 lbs more than the SeaArk Mud Runner 180 2013 at 7 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 140 hp, the SeaArk Coastal 200 (SC) 2009 has a 90-hp advantage over the SeaArk Mud Runner 180 2013'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 Coastal 200 (SC) 2009 is rated for 12 passengers, while the SeaArk Mud Runner 180 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 Coastal 200 (SC) 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk Mud Runner 180 2013 comes in at 0 lbs per hp versus 1 lbs per hp for the SeaArk Coastal 200 (SC) 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.
