The Lund 1625 Rebel XL Sport 2009 is a modified-V design and the Lund 1648 2008 is a flat-bottom 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 1625 Rebel XL Sport 2009 at 16,0 ft versus Lund 1648 2008 at 15,0 ft. Weight tells a clearer story for trailering families: the Lund 1625 Rebel XL Sport 2009 tips the scales at 890 lbs - 470 lbs more than the Lund 1648 2008 at 420 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 75 hp, the Lund 1625 Rebel XL Sport 2009 has a 40-hp advantage over the Lund 1648 2008's 35-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.

At this size, power-to-weight ratio matters more than outright horsepower. The Lund 1625 Rebel XL Sport 2009 comes in at 12 lbs per hp versus 12 lbs per hp for the Lund 1648 2008. 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.
