When two boats share the same hull type — in this case both the Lund 1625 Classic Sport 2007 and the Lund 1825 Rebel XL Sport 2011 are modified vee designs with aluminum construction — 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 1625 Classic Sport 2007 at 16,0 ft versus Lund 1825 Rebel XL Sport 2011 at 18,3 ft. Weight tells a clearer story for trailering families: the Lund 1825 Rebel XL Sport 2011 tips the scales at 965 lbs — 886 lbs less than the Lund 1625 Classic Sport 2007 at 79 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 125 hp, the Lund 1825 Rebel XL Sport 2011 has a 75-hp advantage over the Lund 1625 Classic Sport 2007's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Lund 1825 Rebel XL Sport 2011 is rated for 5 passengers, while the Lund 1625 Classic Sport 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1825 Rebel XL Sport 2011 could be the deciding factor.
Bottom line: Choose the Lund 1825 Rebel XL Sport 2011 if your priority is putting more people on the water — it handles 5 passengers and at 18,3 ft it has the deck room to back that rating up comfortably. The Lund 1625 Classic Sport 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
