Detailed Evaluation & Buyer Recommendation
Alumacraft Competitor 185 Tiller 2012 vs Alumacraft Navigator 175 Sport 2007 — Same Brand, Different Boat
Matching a deep vee Alumacraft Competitor 185 Tiller 2012 against a modified vee Alumacraft Navigator 175 Sport 2007 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Alumacraft Competitor 185 Tiller 2012 at 18,7 ft versus Alumacraft Navigator 175 Sport 2007 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Sport 2007 tips the scales at 1 357 lbs — 1 344 lbs less than the Alumacraft Competitor 185 Tiller 2012 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.
The power gap is worth calling out. Rated to 150 hp, the Alumacraft Navigator 175 Sport 2007 has a 60-hp advantage over the Alumacraft Competitor 185 Tiller 2012's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Alumacraft Competitor 185 Tiller 2012 carries 35 gallons versus 4 gallons in the Alumacraft Navigator 175 Sport 2007. 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 Alumacraft Competitor 185 Tiller 2012 is rated for 6 passengers, while the Alumacraft Navigator 175 Sport 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Competitor 185 Tiller 2012 could be the deciding factor.
Bottom line: Choose the Alumacraft Competitor 185 Tiller 2012 if your priority is putting more people on the water — it handles 6 passengers and at 18,7 ft it has the deck room to back that rating up comfortably. The Alumacraft Navigator 175 Sport 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
