When two boats share the same hull type — in this case both the Alumacraft Fisherman 145 Tiller 2007 and the Alumacraft PF170 2006 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 Fisherman 145 Tiller 2007 at 14,0 ft versus Alumacraft PF170 2006 at 17,0 ft. At 46 lbs and 8 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 60 hp, the Alumacraft PF170 2006 has a 35-hp advantage over the Alumacraft Fisherman 145 Tiller 2007's 25-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 PF170 2006 comes in at 0 lbs per hp versus 2 lbs per hp for the Alumacraft Fisherman 145 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: The Alumacraft PF170 2006 at 17,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumacraft Fisherman 145 Tiller 2007 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.
