Matching a other Alumacraft Fisherman 145 CS 2009 against a flat Alumacraft Pro 175 2011 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 Pro 175 2011 measures 17,4 feet overall (2011), giving it roughly 3,4 additional feet of deck space compared to the Alumacraft Fisherman 145 CS 2009 at 14,0 feet (2009). Weight tells a clearer story for trailering families: the Alumacraft Fisherman 145 CS 2009 tips the scales at 602 lbs — 601 lbs more than the Alumacraft Pro 175 2011 at 1 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 Pro 175 2011 has a 55-hp advantage over the Alumacraft Fisherman 145 CS 2009's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 4 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 Pro 175 2011 comes in at 0 lbs per hp versus 17 lbs per hp for the Alumacraft Fisherman 145 CS 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.
Bottom line: The Alumacraft Pro 175 2011 at 17,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumacraft Fisherman 145 CS 2009 at 14,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
