When two boats share the same hull type — in this case both the Lund 170WPE 2005 and the Lund 1810 Predator SS 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 170WPE 2005 at 17,0 ft versus Lund 1810 Predator SS 2011 at 18,1 ft. At 995 lbs and 965 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.
Both boats share a closely matched power ceiling — 115 hp for the Lund 170WPE 2005 and 125 hp for the Lund 1810 Predator SS 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 1810 Predator SS 2011 carries 19 gallons versus 2 gallons in the Lund 170WPE 2005. 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 1810 Predator SS 2011 is rated for 5 passengers, while the Lund 170WPE 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1810 Predator SS 2011 could be the deciding factor.
Bottom line: Choose the Lund 1810 Predator SS 2011 if your priority is putting more people on the water — it handles 5 passengers and at 18,1 ft it has the deck room to back that rating up comfortably. The Lund 170WPE 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
