When two boats share the same hull type — in this case both the Lund 1852MT 2008 and the Lund 186 Pro Sport GL 2009 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 1852MT 2008 at 18,0 ft versus Lund 186 Pro Sport GL 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Lund 1852MT 2008 tips the scales at 475 lbs — 300 lbs more than the Lund 186 Pro Sport GL 2009 at 175 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.
The Lund 1852MT 2008 carries a rated maximum of 45 hp. Engine data for the Lund 186 Pro Sport GL 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The Lund 1852MT 2008 is rated for 6 passengers, while the Lund 186 Pro Sport GL 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1852MT 2008 could be the deciding factor.
Bottom line: Choose the Lund 1852MT 2008 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lund 186 Pro Sport GL 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
