When two boats share the same hull type — in this case both the Sea Fox 160CC 2009 and the Sea Fox 187CC 2011 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 2009 at 16,0 ft versus Sea Fox 187CC 2011 at 18,0 ft. At 115 lbs and 19 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 140 hp, the Sea Fox 187CC 2011 has a 60-hp advantage over the Sea Fox 160CC 2009'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 187CC 2011 carries 51 gallons versus 21 gallons in the Sea Fox 160CC 2009. 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 187CC 2011 is rated for 6 passengers, while the Sea Fox 160CC 2009 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 187CC 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sea Fox 187CC 2011 comes in at 0 lbs per hp versus 1 lbs per hp for the Sea Fox 160CC 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.
