The Lund 1625 Classic SS 2007 vs Lund 1675 Adventure SS/Sport 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 1625 Classic SS 2007 at 16,0 ft versus Lund 1675 Adventure SS/Sport 2021 at 16,1 ft. Weight tells a clearer story for trailering families: the Lund 1675 Adventure SS/Sport 2021 tips the scales at 1 350 lbs - 685 lbs less than the Lund 1625 Classic SS 2007 at 665 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 90 hp, the Lund 1675 Adventure SS/Sport 2021 has a 50-hp advantage over the Lund 1625 Classic SS 2007's 40-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 4 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund 1675 Adventure SS/Sport 2021 comes in at 15 lbs per hp versus 17 lbs per hp for the Lund 1625 Classic SS 2007. 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 1625 Classic SS 2007 isn't listed as trailerable, which may mean a permanent berth or mooring is required.
Bottom line: Performance buyers should lean toward the Lund 1675 Adventure SS/Sport 2021 and its 90-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 1625 Classic SS 2007 with its 40-hp rating is the more economical daily driver.
