When two boats share the same hull type — in this case both the Lund 1700 Pro Sport Vazer 2008 and the Lund 1975 Pro-V IFS®/SE 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?
The power gap is worth calling out. Rated to 225 hp, the Lund 1975 Pro-V IFS®/SE 2012 has a 125-hp advantage over the Lund 1700 Pro Sport Vazer 2008's 100-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 1975 Pro-V IFS®/SE 2012 carries 51 gallons versus 2 gallons in the Lund 1700 Pro Sport Vazer 2008. 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.
Bottom line: The Lund 1975 Pro-V IFS®/SE 2012 at 19,7 ft is the right call if deck space, comfort, and entertaining are top of your list. The Lund 1700 Pro Sport Vazer 2008 at 17,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
