Both the Lund 1800 Alaskan Tiller 2012 and the Lund 1825 Rebel XL Sport 2009 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 1800 Alaskan Tiller 2012 at 18,8 ft versus Lund 1825 Rebel XL Sport 2009 at 18,0 ft. At 975 lbs and 965 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.
The power gap is worth calling out. Rated to 115 hp, the Lund 1825 Rebel XL Sport 2009 has a 40-hp advantage over the Lund 1800 Alaskan Tiller 2012's 75-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 19 gal and 19 gal - so range won't be a tiebreaker here.
Both boats are rated for 5 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.
Bottom line: Performance buyers should lean toward the Lund 1825 Rebel XL Sport 2009 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 1800 Alaskan Tiller 2012 with its 75-hp rating is the more economical daily driver.
