When two boats share the same hull type — in this case both the Sea Fox 172CC Pro Series 2012 and the Sea Fox 205 BF Pro 2007 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?
Size is the most obvious dividing line here. The Sea Fox 172CC Pro Series 2012 measures 17,1 feet overall (2012), giving it roughly 15,1 additional feet of deck space compared to the Sea Fox 205 BF Pro 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Fox 172CC Pro Series 2012 tips the scales at 155 lbs — 131 lbs more than the Sea Fox 205 BF Pro 2007 at 24 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 200 hp, the Sea Fox 205 BF Pro 2007 has a 85-hp advantage over the Sea Fox 172CC Pro Series 2012's 115-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 6 gallons in the Sea Fox 205 BF Pro 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Sea Fox 205 BF Pro 2007 is rated for 8 passengers, while the Sea Fox 172CC Pro Series 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Fox 205 BF Pro 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Sea Fox 205 BF Pro 2007 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.
Bottom line: Choose the Sea Fox 205 BF Pro 2007 if your priority is putting more people on the water — it handles 8 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Sea Fox 172CC Pro Series 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
