The Grady-White Canyon 336 2012 vs Grady-White Journey 258 2008 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.
Size is the most obvious dividing line here. The Grady-White Canyon 336 2012 measures 33,5 feet overall (2012), giving it roughly 9,5 additional feet of deck space compared to the Grady-White Journey 258 2008 at 24,0 feet (2008). Weight tells a clearer story for trailering families: the Grady-White Canyon 336 2012 tips the scales at 9 200 lbs - 4 880 lbs more than the Grady-White Journey 258 2008 at 4 320 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 700 hp, the Grady-White Canyon 336 2012 has a 350-hp advantage over the Grady-White Journey 258 2008's 350-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Grady-White Canyon 336 2012 carries 350 gallons versus 127 gallons in the Grady-White Journey 258 2008. 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 Grady-White Canyon 336 2012 is rated for 10 passengers, while the Grady-White Journey 258 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grady-White Canyon 336 2012 could be the deciding factor.
Bottom line: Choose the Grady-White Canyon 336 2012 if your priority is putting more people on the water - it handles 10 passengers and at 33,5 ft it has the deck room to back that rating up comfortably. The Grady-White Journey 258 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
