The Lund 1448 2008 is a flat-bottom design and the Lund 1625 Rebel SS 2011 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.
On paper these two are close siblings in the size department - Lund 1448 2008 at 14,0 ft versus Lund 1625 Rebel SS 2011 at 16,3 ft. Weight tells a clearer story for trailering families: the Lund 1625 Rebel SS 2011 tips the scales at 640 lbs - 275 lbs less than the Lund 1448 2008 at 365 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.
Both boats share a closely matched power ceiling - 25 hp for the Lund 1448 2008 and 40 hp for the Lund 1625 Rebel SS 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
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 1448 2008 comes in at 15 lbs per hp versus 16 lbs per hp for the Lund 1625 Rebel SS 2011. 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.
Bottom line: The Lund 1625 Rebel SS 2011 at 16,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Lund 1448 2008 at 14,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
