The Lund 1448M Jon 2011 is a flat-bottom design and the Lund 1660 Classic Tiller 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.
On paper these two are close siblings in the size department - Lund 1448M Jon 2011 at 15,8 ft versus Lund 1660 Classic Tiller 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the Lund 1660 Classic Tiller 2008 tips the scales at 785 lbs - 420 lbs less than the Lund 1448M Jon 2011 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.
The power gap is worth calling out. Rated to 60 hp, the Lund 1660 Classic Tiller 2008 has a 35-hp advantage over the Lund 1448M 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund 1660 Classic Tiller 2008 comes in at 13 lbs per hp versus 15 lbs per hp for the Lund 1448M Jon 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: Performance buyers should lean toward the Lund 1660 Classic Tiller 2008 and its 60-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 1448M Jon 2011 with its 25-hp rating is the more economical daily driver.
