The Lund 1675 Adventure SS/Sport 2021 vs Lund 1810 Predator SS 2009 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 Adventure SS/Sport 2021 at 16,1 ft versus Lund 1810 Predator SS 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Lund 1675 Adventure SS/Sport 2021 tips the scales at 1 350 lbs — 455 lbs more than the Lund 1810 Predator SS 2009 at 895 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 115 hp, the Lund 1810 Predator SS 2009 has a 25-hp advantage over the Lund 1675 Adventure SS/Sport 2021's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 21 gal and 19 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Lund 1810 Predator SS 2009 is rated for 5 passengers, while the Lund 1675 Adventure SS/Sport 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 1810 Predator SS 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund 1810 Predator SS 2009 comes in at 8 lbs per hp versus 15 lbs per hp for the Lund 1675 Adventure SS/Sport 2021. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
The Lund 1675 Adventure SS/Sport 2021 is trailerable — a genuine lifestyle advantage at this size. The Lund 1810 Predator SS 2009 isn't listed as trailerable, which may mean a permanent berth or mooring is required.
Bottom line: Choose the Lund 1810 Predator SS 2009 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lund 1675 Adventure SS/Sport 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.
