Alumacraft Competitor 185 Tiller 2013 vs Alumacraft Navigator 165 Sport 2005 — Same Brand, Different Boat

The Alumacraft Competitor 185 Tiller 2013 vs Alumacraft Navigator 165 Sport 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Alumacraft Competitor 185 Tiller 2013 at 18,7 ft versus Alumacraft Navigator 165 Sport 2005 at 16,0 ft. At 13 lbs and 105 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 — 90 hp for the Alumacraft Competitor 185 Tiller 2013 and 90 hp for the Alumacraft Navigator 165 Sport 2005. 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 Tiller 2013 carries 34 gallons versus 23 gallons in the Alumacraft Navigator 165 Sport 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 Alumacraft Competitor 185 Tiller 2013 is rated for 6 passengers, while the Alumacraft Navigator 165 Sport 2005 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 2013 could be the deciding factor.

Bottom line: Choose the Alumacraft Competitor 185 Tiller 2013 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 165 Sport 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Alumacraft Competitor 185 Tiller 2013 vs Alumacraft Navigator 165 Sport 2005 — Common Questions

Which is the larger boat — the Alumacraft Competitor 185 Tiller 2013 or the Alumacraft Navigator 165 Sport 2005?
The Alumacraft Competitor 185 Tiller 2013 is the longer of the two at 18,7 feet overall. The Alumacraft Navigator 165 Sport 2005 comes in at 16,0 feet, making it roughly 2,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Competitor 185 Tiller 2013 or the Alumacraft Navigator 165 Sport 2005?
For trailering, the Alumacraft Competitor 185 Tiller 2013 has the edge at 13 lbs dry weight versus 105 lbs for the Alumacraft Navigator 165 Sport 2005. 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 Tiller 2013 is Coast Guard rated for 6 passengers, while the Alumacraft Navigator 165 Sport 2005 is certified for 5. 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 165 Sport 2005 measures 96" wide, compared to 95" for the Alumacraft Competitor 185 Tiller 2013. 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 Tiller 2013 or the Alumacraft Navigator 165 Sport 2005?
The Alumacraft Competitor 185 Tiller 2013 has the bigger tank at 34 gallons, versus 23 gallons on the Alumacraft Navigator 165 Sport 2005. That 11-gallon difference translates to roughly 33–55 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Competitor 185 Tiller 2013 and Alumacraft Navigator 165 Sport 2005 from the same manufacturer?
Yes — both the Alumacraft Competitor 185 Tiller 2013 and the Alumacraft Navigator 165 Sport 2005 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.
