The Whittley CW2100 2009 vs Whittley Voyager 580 2007 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 Whittley CW2100 2009 measures 21,0 feet overall (2009), giving it roughly 19,0 additional feet of deck space compared to the Whittley Voyager 580 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Whittley Voyager 580 2007 tips the scales at 318 lbs — 151 lbs less than the Whittley CW2100 2009 at 167 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 225 hp, the Whittley CW2100 2009 has a 50-hp advantage over the Whittley Voyager 580 2007'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 Whittley CW2100 2009 carries 59 gallons versus 34 gallons in the Whittley Voyager 580 2007. 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 Whittley CW2100 2009 is rated for 6 passengers, while the Whittley Voyager 580 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Whittley CW2100 2009 could be the deciding factor.
