When two boats share the same hull type — in this case both the Lund 1675 Impact Sport 2012 and the Lund 1800 Pro-V Tiller 2008 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 Sport 2012 at 16,8 ft versus Lund 1800 Pro-V Tiller 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Lund 1675 Impact Sport 2012 tips the scales at 1 055 lbs — 1 040 lbs more than the Lund 1800 Pro-V Tiller 2008 at 15 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 Sport 2012 and 90 hp for the Lund 1800 Pro-V Tiller 2008. 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 1675 Impact Sport 2012 carries 19 gallons versus 4 gallons in the Lund 1800 Pro-V Tiller 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Lund 1800 Pro-V Tiller 2008 comes in at 0 lbs per hp versus 12 lbs per hp for the Lund 1675 Impact Sport 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.
