Both the Sea Fox 205BF 2010 and the Sea Fox 216WA 2010 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 205BF 2010 at 20,5 ft versus Sea Fox 216WA 2010 at 21,3 ft. Weight tells a clearer story for trailering families: the Sea Fox 216WA 2010 tips the scales at 2 900 lbs - 500 lbs less than the Sea Fox 205BF 2010 at 2 400 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.
Both boats share a closely matched power ceiling - 200 hp for the Sea Fox 205BF 2010 and 200 hp for the Sea Fox 216WA 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sea Fox 216WA 2010 carries 101 gallons versus 60 gallons in the Sea Fox 205BF 2010. 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 216WA 2010 is rated for 8 passengers, while the Sea Fox 205BF 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Fox 216WA 2010 could be the deciding factor.
Bottom line: Choose the Sea Fox 216WA 2010 if your priority is putting more people on the water - it handles 8 passengers and at 21,3 ft it has the deck room to back that rating up comfortably. The Sea Fox 205BF 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
