The Lund 1675 Impact XS 2021 vs Lund 1875 Impact SS 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Lund 1675 Impact XS 2021 at 16,1 ft versus Lund 1875 Impact SS 2012 at 18,8 ft. Weight tells a clearer story for trailering families: the Lund 1675 Impact XS 2021 tips the scales at 1 320 lbs — 105 lbs more than the Lund 1875 Impact SS 2012 at 1 215 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 1875 Impact SS 2012 has a 60-hp advantage over the Lund 1675 Impact XS 2021's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lund 1875 Impact SS 2012 carries 32 gallons versus 22 gallons in the Lund 1675 Impact XS 2021. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Lund 1875 Impact SS 2012 is rated for 5 passengers, while the Lund 1675 Impact XS 2021 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1875 Impact SS 2012 could be the deciding factor.
Bottom line: Choose the Lund 1875 Impact SS 2012 if your priority is putting more people on the water — it handles 5 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Lund 1675 Impact XS 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
