When two boats share the same hull type — in this case both the Lund 1700 Fisherman OB 2006 and the Lund 1875 Impact Sport 2011 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 1700 Fisherman OB 2006 at 17,0 ft versus Lund 1875 Impact Sport 2011 at 18,8 ft. Weight tells a clearer story for trailering families: the Lund 1875 Impact Sport 2011 tips the scales at 1 265 lbs — 1 252 lbs less than the Lund 1700 Fisherman OB 2006 at 13 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 — 150 hp for the Lund 1700 Fisherman OB 2006 and 150 hp for the Lund 1875 Impact Sport 2011. 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 1875 Impact Sport 2011 carries 32 gallons versus 27 gallons in the Lund 1700 Fisherman OB 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Lund 1700 Fisherman OB 2006 is rated for 7 passengers, while the Lund 1875 Impact Sport 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1700 Fisherman OB 2006 could be the deciding factor.
