The Lund 1660 Classic SS 2007 is a modified-V design and the Lund 1825 Rebel XL SS 2013 is a deep-V design, so you're likely deciding between two noticeably 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 - Lund 1660 Classic SS 2007 at 16,0 ft versus Lund 1825 Rebel XL SS 2013 at 18,3 ft. At 840 lbs and 895 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.

The power gap is worth calling out. Rated to 125 hp, the Lund 1825 Rebel XL SS 2013 has a 50-hp advantage over the Lund 1660 Classic SS 2007's 75-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 19 gal and 19 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Lund 1825 Rebel XL SS 2013 is rated for 6 passengers, while the Lund 1660 Classic SS 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1825 Rebel XL SS 2013 could be the deciding factor.
