The Sea Fox 205BF 2009 vs Sea Fox 236 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - Sea Fox 205BF 2009 at 20,0 ft versus Sea Fox 236 2006 at 23,0 ft. Weight tells a clearer story for trailering families: the Sea Fox 236 2006 tips the scales at 2 700 lbs - 300 lbs less than the Sea Fox 205BF 2009 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.
The power gap is worth calling out. Rated to 250 hp, the Sea Fox 236 2006 has a 75-hp advantage over the Sea Fox 205BF 2009's 175-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 236 2006 carries 122 gallons versus 60 gallons in the Sea Fox 205BF 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 236 2006 is rated for 8 passengers, while the Sea Fox 205BF 2009 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 236 2006 could be the deciding factor.
Bottom line: Choose the Sea Fox 236 2006 if your priority is putting more people on the water - it handles 8 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Sea Fox 205BF 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
