When two boats share the same hull type — in this case both the Lund 186 Pro Sport GL 2010 and the Lund A 14 Tiller 2009 are modified vee designs with fiberglass 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?
Size is the most obvious dividing line here. The Lund 186 Pro Sport GL 2010 measures 18,5 feet overall (2010), giving it roughly 4,5 additional feet of deck space compared to the Lund A 14 Tiller 2009 at 14,0 feet (2009). Weight tells a clearer story for trailering families: the Lund A 14 Tiller 2009 tips the scales at 194 lbs — 176 lbs less than the Lund 186 Pro Sport GL 2010 at 18 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 A 14 Tiller 2009 tops out at 15 hp. Engine specs for the Lund 186 Pro Sport GL 2010 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Lund 186 Pro Sport GL 2010 is rated for 5 passengers, while the Lund A 14 Tiller 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 186 Pro Sport GL 2010 could be the deciding factor.
Bottom line: Choose the Lund 186 Pro Sport GL 2010 if your priority is putting more people on the water — it handles 5 passengers and at 18,5 ft it has the deck room to back that rating up comfortably. The Lund A 14 Tiller 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
