Both the Lund 1450 Rebel Tiller 2006 and the Lund 1625 Rebel Tiller 2010 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Lund 1450 Rebel Tiller 2006 at 14,0 ft versus Lund 1625 Rebel Tiller 2010 at 16,3 ft. At 615 lbs and 595 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 40 hp for the Lund 1450 Rebel Tiller 2006 and 40 hp for the Lund 1625 Rebel Tiller 2010. 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 1625 Rebel Tiller 2010 comes in at 15 lbs per hp versus 15 lbs per hp for the Lund 1450 Rebel Tiller 2006. 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 Tiller 2010 at 16,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Lund 1450 Rebel Tiller 2006 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.
