Alumacraft 1648 2006 vs Alumacraft Tournament Pro 185 CS 2003 — Same Brand, Different Boat

The Alumacraft 1648 2006 vs Alumacraft Tournament Pro 185 CS 2003 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.

The power gap is worth calling out. Rated to 200 hp, the Alumacraft Tournament Pro 185 CS 2003 has a 165-hp advantage over the Alumacraft 1648 2006's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Tournament Pro 185 CS 2003 is rated for 6 passengers, while the Alumacraft 1648 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Tournament Pro 185 CS 2003 could be the deciding factor.

Bottom line: Choose the Alumacraft Tournament Pro 185 CS 2003 if your priority is putting more people on the water — it handles 6 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Alumacraft 1648 2006 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 1648 2006 vs Alumacraft Tournament Pro 185 CS 2003 — Common Questions

Which is easier to trailer — the Alumacraft 1648 2006 or the Alumacraft Tournament Pro 185 CS 2003?
For trailering, the Alumacraft Tournament Pro 185 CS 2003 has the edge at 151 lbs dry weight versus 285 lbs for the Alumacraft 1648 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.
Which boat can handle a bigger outboard?
The Alumacraft Tournament Pro 185 CS 2003 is rated to a maximum of 200 hp, giving it the larger power ceiling. The Alumacraft 1648 2006 tops out at 35 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Alumacraft 1648 2006 is Coast Guard rated for 5 passengers, while the Alumacraft Tournament Pro 185 CS 2003 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 Tournament Pro 185 CS 2003 measures 96" wide, compared to 7" for the Alumacraft 1648 2006. 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.
Are the Alumacraft 1648 2006 and Alumacraft Tournament Pro 185 CS 2003 from the same manufacturer?
Yes — both the Alumacraft 1648 2006 and the Alumacraft Tournament Pro 185 CS 2003 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.
