Matching a tunnel SeaArk 1872 Tunnel Pro (CC) 2013 against a modified vee SeaArk Rebel 15 2009 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 1872 Tunnel Pro (CC) 2013 at 18,0 ft versus SeaArk Rebel 15 2009 at 15,0 ft. At 78 lbs and 6 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 1872 Tunnel Pro (CC) 2013 could be the deciding factor.
