Both the Sea Fox 21 BF Sport 2007 and the Sea Fox 236CC Pro Series 2012 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 21 BF Sport 2007 at 21,0 ft versus Sea Fox 236CC Pro Series 2012 at 23,0 ft. Weight tells a clearer story for trailering families: the Sea Fox 236CC Pro Series 2012 tips the scales at 2 800 lbs - 700 lbs less than the Sea Fox 21 BF Sport 2007 at 2 100 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 250 hp, the Sea Fox 236CC Pro Series 2012 has a 50-hp advantage over the Sea Fox 21 BF Sport 2007's 200-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 236CC Pro Series 2012 carries 101 gallons versus 47 gallons in the Sea Fox 21 BF Sport 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 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.
