The Lund 1800 Alaskan 2005 vs Lund 1875 Renegade SS 2021 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 1800 Alaskan 2005 at 18,0 ft versus Lund 1875 Renegade SS 2021 at 18,9 ft. Weight tells a clearer story for trailering families: the Lund 1875 Renegade SS 2021 tips the scales at 1 400 lbs — 1 301 lbs less than the Lund 1800 Alaskan 2005 at 99 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.
Both boats share a closely matched power ceiling — 90 hp for the Lund 1800 Alaskan 2005 and 75 hp for the Lund 1875 Renegade SS 2021. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 19 gal and 22 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Lund 1800 Alaskan 2005 is rated for 7 passengers, while the Lund 1875 Renegade SS 2021 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1800 Alaskan 2005 could be the deciding factor.
Bottom line: Choose the Lund 1800 Alaskan 2005 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lund 1875 Renegade SS 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
