Detailed Evaluation & Buyer Recommendation
Alumacraft Fisherman 145 CS 2003 vs Alumacraft Navigator 185 CS 2006 — Same Brand, Different Boat
The Alumacraft Fisherman 145 CS 2003 vs Alumacraft Navigator 185 CS 2006 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 150 hp, the Alumacraft Navigator 185 CS 2006 has a 115-hp advantage over the Alumacraft Fisherman 145 CS 2003'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 Navigator 185 CS 2006 is rated for 6 passengers, while the Alumacraft Fisherman 145 CS 2003 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 185 CS 2006 could be the deciding factor.
Bottom line: Choose the Alumacraft Navigator 185 CS 2006 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Alumacraft Fisherman 145 CS 2003 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
