The Sailfish 2660 WAC 2009 is a modified-V design and the Sailfish 320 CC 2013 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Sailfish 320 CC 2013 measures 31,5 feet overall (2013), giving it roughly 5,5 additional feet of deck space compared to the Sailfish 2660 WAC 2009 at 26,0 feet (2009). Weight tells a clearer story for trailering families: the Sailfish 320 CC 2013 tips the scales at 7 200 lbs - 2 450 lbs less than the Sailfish 2660 WAC 2009 at 4 750 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 Sailfish 320 CC 2013 has a 450-hp advantage over the Sailfish 2660 WAC 2009's 250-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sailfish 320 CC 2013 carries 300 gallons versus 200 gallons in the Sailfish 2660 WAC 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 Sailfish 320 CC 2013 is rated for 10 passengers, while the Sailfish 2660 WAC 2009 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sailfish 320 CC 2013 could be the deciding factor.
