The Alumacraft All-Weld MV 1860 AW SC 2012 vs Alumacraft Tournament Pro 175 CS 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 All-Weld MV 1860 AW SC 2012 at 18,0 ft versus Alumacraft Tournament Pro 175 CS 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 175 CS 2005 tips the scales at 1 415 lbs — 540 lbs less than the Alumacraft All-Weld MV 1860 AW SC 2012 at 875 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 175 hp, the Alumacraft Tournament Pro 175 CS 2005 has a 85-hp advantage over the Alumacraft All-Weld MV 1860 AW SC 2012's 90-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 Tournament Pro 175 CS 2005 carries 34 gallons versus 21 gallons in the Alumacraft All-Weld MV 1860 AW SC 2012. 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 All-Weld MV 1860 AW SC 2012 is rated for 6 passengers, while the Alumacraft Tournament Pro 175 CS 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 All-Weld MV 1860 AW SC 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Tournament Pro 175 CS 2005 comes in at 8 lbs per hp versus 10 lbs per hp for the Alumacraft All-Weld MV 1860 AW SC 2012. 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 All-Weld MV 1860 AW SC 2012 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 Tournament Pro 175 CS 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.
