The Lund 1448 Jon 2011 is a flat-bottom design and the Lund 1625 Rebel XL SS 2008 is a modified-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.
The power gap is worth calling out. Rated to 75 hp, the Lund 1625 Rebel XL SS 2008 has a 50-hp advantage over the Lund 1448 Jon 2011's 25-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 4 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Lund 1625 Rebel XL SS 2008 and its 75-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 1448 Jon 2011 with its 25-hp rating is the more economical daily driver.
