When two boats share the same hull type — in this case both the Lund 1675 Impact SS 2011 and the Lund 1725 Pro Guide 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 Impact SS 2011 at 16,8 ft versus Lund 1725 Pro Guide 2012 at 17,3 ft. Weight tells a clearer story for trailering families: the Lund 1675 Impact SS 2011 tips the scales at 1 125 lbs — 1 013 lbs more than the Lund 1725 Pro Guide 2012 at 112 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 1675 Impact SS 2011 and 75 hp for the Lund 1725 Pro Guide 2012. 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. Fuel capacity breaks the other way: the Lund 1725 Pro Guide 2012 carries 27 gallons versus 19 gallons in the Lund 1675 Impact SS 2011. 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 1725 Pro Guide 2012 comes in at 2 lbs per hp versus 13 lbs per hp for the Lund 1675 Impact SS 2011. 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.
