Alumacraft Competitor 185 CS 2012 vs Alumacraft Navigator 185 Sport 2006 — Same Brand, Different Boat

Matching a deep vee Alumacraft Competitor 185 CS 2012 against a modified vee Alumacraft Navigator 185 Sport 2006 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 CS 2012 at 18,7 ft versus Alumacraft Navigator 185 Sport 2006 at 18,0 ft. At 142 lbs and 144 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 — 150 hp for the Alumacraft Competitor 185 CS 2012 and 150 hp for the Alumacraft Navigator 185 Sport 2006. 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 Alumacraft Competitor 185 CS 2012 carries 35 gallons versus 4 gallons in the Alumacraft Navigator 185 Sport 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 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.

Bottom line: The Alumacraft Competitor 185 CS 2012 and Alumacraft Navigator 185 Sport 2006 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Alumacraft Competitor 185 CS 2012 vs Alumacraft Navigator 185 Sport 2006 — Common Questions

Which is the larger boat — the Alumacraft Competitor 185 CS 2012 or the Alumacraft Navigator 185 Sport 2006?
The Alumacraft Competitor 185 CS 2012 is the longer of the two at 18,7 feet overall. The Alumacraft Navigator 185 Sport 2006 comes in at 18,0 feet, making it roughly 0,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Competitor 185 CS 2012 or the Alumacraft Navigator 185 Sport 2006?
For trailering, the Alumacraft Competitor 185 CS 2012 has the edge at 142 lbs dry weight versus 144 lbs for the Alumacraft Navigator 185 Sport 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Alumacraft Competitor 185 CS 2012 is Coast Guard rated for 6 passengers, while the Alumacraft Navigator 185 Sport 2006 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Alumacraft Navigator 185 Sport 2006 measures 96" wide, compared to 95" for the Alumacraft Competitor 185 CS 2012. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Alumacraft Competitor 185 CS 2012 or the Alumacraft Navigator 185 Sport 2006?
The Alumacraft Competitor 185 CS 2012 has the bigger tank at 35 gallons, versus 4 gallons on the Alumacraft Navigator 185 Sport 2006. That 31-gallon difference translates to roughly 93–155 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Competitor 185 CS 2012 and Alumacraft Navigator 185 Sport 2006 from the same manufacturer?
Yes — both the Alumacraft Competitor 185 CS 2012 and the Alumacraft Navigator 185 Sport 2006 are built by Alumacraft. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
