When two boats share the same hull type — in this case both the Alumacraft All-Weld MV 1756 CC 2011 and the Alumacraft Tournament Pro 185 Tiller 2007 are modified vee designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Alumacraft All-Weld MV 1756 CC 2011 at 17,0 ft versus Alumacraft Tournament Pro 185 Tiller 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Tournament Pro 185 Tiller 2007 tips the scales at 1 385 lbs — 1 299 lbs less than the Alumacraft All-Weld MV 1756 CC 2011 at 86 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 90 hp, the Alumacraft Tournament Pro 185 Tiller 2007 has a 40-hp advantage over the Alumacraft All-Weld MV 1756 CC 2011's 50-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 All-Weld MV 1756 CC 2011 carries 21 gallons versus 4 gallons in the Alumacraft Tournament Pro 185 Tiller 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft All-Weld MV 1756 CC 2011 comes in at 2 lbs per hp versus 15 lbs per hp for the Alumacraft Tournament Pro 185 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: Performance buyers should lean toward the Alumacraft Tournament Pro 185 Tiller 2007 and its 90-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumacraft All-Weld MV 1756 CC 2011 with its 50-hp rating is the more economical daily driver.
