When two boats share the same hull type — in this case both the Sea Fox 160CC Pro Series 2012 and the Sea Fox 172CC Pro Series 2012 are modified vee designs with fiberglass 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 — Sea Fox 160CC Pro Series 2012 at 16,1 ft versus Sea Fox 172CC Pro Series 2012 at 17,1 ft. Weight tells a clearer story for trailering families: the Sea Fox 172CC Pro Series 2012 tips the scales at 155 lbs — 142 lbs less than the Sea Fox 160CC Pro Series 2012 at 13 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 115 hp, the Sea Fox 172CC Pro Series 2012 has a 35-hp advantage over the Sea Fox 160CC Pro Series 2012's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Fox 172CC Pro Series 2012 carries 27 gallons versus 21 gallons in the Sea Fox 160CC Pro Series 2012. 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 Sea Fox 160CC Pro Series 2012 comes in at 0 lbs per hp versus 1 lbs per hp for the Sea Fox 172CC Pro Series 2012. 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.
