Matching a tunnel SeaArk Jet Tunnel 1860MVJT 2008 against a flat SeaArk Mud Runner 170 2012 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 Jet Tunnel 1860MVJT 2008 at 18,0 ft versus SeaArk Mud Runner 170 2012 at 16,8 ft.
