Both the Lund 1825 Explorer SS 2009 and the Lund SSV 18 2011 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 1825 Explorer SS 2009 at 18,0 ft versus Lund SSV 18 2011 at 18,3 ft. Weight tells a clearer story for trailering families: the Lund 1825 Explorer SS 2009 tips the scales at 1 400 lbs - 940 lbs more than the Lund SSV 18 2011 at 460 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 150 hp, the Lund 1825 Explorer SS 2009 has a 90-hp advantage over the Lund SSV 18 2011's 60-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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 Explorer SS 2009 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund SSV 18 2011 with its 60-hp rating is the more economical daily driver.
