Matching a flat Alumacraft 1236 2007 against a deep vee Alumacraft Navigator 175 Tiller 2009 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.

Size is the most obvious dividing line here. The Alumacraft Navigator 175 Tiller 2009 measures 17,0 feet overall (2009), giving it roughly 5,0 additional feet of deck space compared to the Alumacraft 1236 2007 at 12,0 feet (2007). Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Tiller 2009 tips the scales at 1 145 lbs — 1 020 lbs less than the Alumacraft 1236 2007 at 125 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 2009 has a 60-hp advantage over the Alumacraft 1236 2007's 15-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 2009 is rated for 5 passengers, while the Alumacraft 1236 2007 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 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft 1236 2007 comes in at 8 lbs per hp versus 15 lbs per hp for the Alumacraft Navigator 175 Tiller 2009. 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.
