Alumacraft Navigator Classic 165 2005 vs Alumacraft Pro 175 2011 — Same Brand, Different Boat

The Alumacraft Navigator Classic 165 2005 vs Alumacraft Pro 175 2011 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 Navigator Classic 165 2005 at 16,0 ft versus Alumacraft Pro 175 2011 at 17,4 ft. At 66 lbs and 1 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.

The power gap is worth calling out. Rated to 90 hp, the Alumacraft Pro 175 2011 has a 40-hp advantage over the Alumacraft Navigator Classic 165 2005's 50-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 Navigator Classic 165 2005 is rated for 5 passengers, while the Alumacraft Pro 175 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Navigator Classic 165 2005 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Pro 175 2011 comes in at 0 lbs per hp versus 1 lbs per hp for the Alumacraft Navigator Classic 165 2005. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Choose the Alumacraft Navigator Classic 165 2005 if your priority is putting more people on the water — it handles 5 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Alumacraft Pro 175 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Alumacraft Navigator Classic 165 2005 vs Alumacraft Pro 175 2011 — Common Questions

Which is the larger boat — the Alumacraft Navigator Classic 165 2005 or the Alumacraft Pro 175 2011?
The Alumacraft Pro 175 2011 is the longer of the two at 17,4 feet overall. The Alumacraft Navigator Classic 165 2005 comes in at 16,0 feet, making it roughly 1,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Navigator Classic 165 2005 or the Alumacraft Pro 175 2011?
For trailering, the Alumacraft Pro 175 2011 has the edge at 1 lbs dry weight versus 66 lbs for the Alumacraft Navigator Classic 165 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.
Which boat can handle a bigger outboard?
The Alumacraft Pro 175 2011 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Alumacraft Navigator Classic 165 2005 tops out at 50 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 Navigator Classic 165 2005 is Coast Guard rated for 5 passengers, while the Alumacraft Pro 175 2011 is certified for 4. 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 has the better power-to-weight ratio?
The Alumacraft Pro 175 2011 has a better power-to-weight ratio at 0 lbs per hp compared to 1 lbs per hp for the Alumacraft Navigator Classic 165 2005. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Alumacraft Pro 175 2011 measures 88" wide, compared to 76" for the Alumacraft Navigator Classic 165 2005. 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 Navigator Classic 165 2005 and Alumacraft Pro 175 2011 from the same manufacturer?
Yes — both the Alumacraft Navigator Classic 165 2005 and the Alumacraft Pro 175 2011 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.
