The Lund 1425 Classic Tiller 2007 is a modified-V design and the Lund 1436L Jon 2013 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 1425 Classic Tiller 2007 at 14,0 ft versus Lund 1436L Jon 2013 at 14,0 ft. Weight tells a clearer story for trailering families: the Lund 1425 Classic Tiller 2007 tips the scales at 590 lbs - 445 lbs more than the Lund 1436L Jon 2013 at 145 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 40 hp, the Lund 1425 Classic Tiller 2007 has a 25-hp advantage over the Lund 1436L Jon 2013's 15-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 1436L Jon 2013 comes in at 10 lbs per hp versus 15 lbs per hp for the Lund 1425 Classic Tiller 2007. 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 1425 Classic Tiller 2007 and its 40-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 1436L Jon 2013 with its 15-hp rating is the more economical daily driver.
