When two boats share the same hull type — in this case both the Lund 1625 Classic Sport 2007 and the Lund 1825 Explorer Sport 2010 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 Explorer Sport 2010 at 18,3 ft. At 79 lbs and 145 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 150 hp, the Lund 1825 Explorer Sport 2010 has a 100-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 Explorer Sport 2010 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 Explorer Sport 2010 could be the deciding factor.
Bottom line: Choose the Lund 1825 Explorer Sport 2010 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.
