Alumacraft Navigator 165 Tiller 2007 vs Alumacraft Trophy 175 2011 — Same Brand, Different Boat

Matching a modified vee Alumacraft Navigator 165 Tiller 2007 against a deep vee Alumacraft Trophy 175 2011 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 Navigator 165 Tiller 2007 at 16,0 ft versus Alumacraft Trophy 175 2011 at 17,7 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 165 Tiller 2007 tips the scales at 925 lbs — 770 lbs more than the Alumacraft Trophy 175 2011 at 155 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 Trophy 175 2011 has a 90-hp advantage over the Alumacraft Navigator 165 Tiller 2007's 60-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 Trophy 175 2011 carries 38 gallons versus 22 gallons in the Alumacraft Navigator 165 Tiller 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 Trophy 175 2011 is rated for 7 passengers, while the Alumacraft Navigator 165 Tiller 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 Trophy 175 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Trophy 175 2011 comes in at 1 lbs per hp versus 15 lbs per hp for the Alumacraft Navigator 165 Tiller 2007. 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 Trophy 175 2011 if your priority is putting more people on the water — it handles 7 passengers and at 17,7 ft it has the deck room to back that rating up comfortably. The Alumacraft Navigator 165 Tiller 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.

Alumacraft Navigator 165 Tiller 2007 vs Alumacraft Trophy 175 2011 — Common Questions

Which is the larger boat — the Alumacraft Navigator 165 Tiller 2007 or the Alumacraft Trophy 175 2011?
The Alumacraft Trophy 175 2011 is the longer of the two at 17,7 feet overall. The Alumacraft Navigator 165 Tiller 2007 comes in at 16,0 feet, making it roughly 1,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Navigator 165 Tiller 2007 or the Alumacraft Trophy 175 2011?
For trailering, the Alumacraft Trophy 175 2011 has the edge at 155 lbs dry weight versus 925 lbs for the Alumacraft Navigator 165 Tiller 2007. 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 Trophy 175 2011 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Alumacraft Navigator 165 Tiller 2007 tops out at 60 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 165 Tiller 2007 is Coast Guard rated for 5 passengers, while the Alumacraft Trophy 175 2011 is certified for 7. 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 Trophy 175 2011 has a better power-to-weight ratio at 1 lbs per hp compared to 15 lbs per hp for the Alumacraft Navigator 165 Tiller 2007. 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 Trophy 175 2011 measures 94" wide, compared to 91" for the Alumacraft Navigator 165 Tiller 2007. 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 Navigator 165 Tiller 2007 or the Alumacraft Trophy 175 2011?
The Alumacraft Trophy 175 2011 has the bigger tank at 38 gallons, versus 22 gallons on the Alumacraft Navigator 165 Tiller 2007. That 16-gallon difference translates to roughly 48–80 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Navigator 165 Tiller 2007 and Alumacraft Trophy 175 2011 from the same manufacturer?
Yes — both the Alumacraft Navigator 165 Tiller 2007 and the Alumacraft Trophy 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.
