When two boats share the same hull type — in this case both the Lund 1675 Pro Guide 2012 and the Lund 1775 Impact Sport 2012 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 1675 Pro Guide 2012 at 16,7 ft versus Lund 1775 Impact Sport 2012 at 17,8 ft. At 108 lbs and 122 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 125 hp, the Lund 1775 Impact Sport 2012 has a 50-hp advantage over the Lund 1675 Pro Guide 2012's 75-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 1775 Impact Sport 2012 carries 27 gallons versus 19 gallons in the Lund 1675 Pro Guide 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 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 1775 Impact Sport 2012 comes in at 1 lbs per hp versus 1 lbs per hp for the Lund 1675 Pro Guide 2012. 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.
