When two boats share the same hull type — in this case both the Alumacraft Navigator 175 Tiller 2007 and the Alumacraft Vs and Ts T12V 2011 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?

Size is the most obvious dividing line here. The Alumacraft Navigator 175 Tiller 2007 measures 17,0 feet overall (2007), giving it roughly 5,0 additional feet of deck space compared to the Alumacraft Vs and Ts T12V 2011 at 12,0 feet (2011). Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Tiller 2007 tips the scales at 1 145 lbs — 1 129 lbs more than the Alumacraft Vs and Ts T12V 2011 at 16 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 75 hp, the Alumacraft Navigator 175 Tiller 2007 has a 65-hp advantage over the Alumacraft Vs and Ts T12V 2011's 10-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 175 Tiller 2007 is rated for 5 passengers, while the Alumacraft Vs and Ts T12V 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Navigator 175 Tiller 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Vs and Ts T12V 2011 comes in at 2 lbs per hp versus 15 lbs per hp for the Alumacraft Navigator 175 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.
