Both the Sea Fox 160CC 2010 and the Sea Fox 172CC 2009 are modified-V designs, both built in fibreglass, so 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 2010 at 16,1 ft versus Sea Fox 172CC 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Sea Fox 172CC 2009 tips the scales at 1 350 lbs - 200 lbs less than the Sea Fox 160CC 2010 at 1 150 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 2009 has a 35-hp advantage over the Sea Fox 160CC 2010'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 2009 carries 27 gallons versus 21 gallons in the Sea Fox 160CC 2010. 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 172CC 2009 comes in at 12 lbs per hp versus 14 lbs per hp for the Sea Fox 160CC 2010. 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: Performance buyers should lean toward the Sea Fox 172CC 2009 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Fox 160CC 2010 with its 80-hp rating is the more economical daily driver.
