Both the Sailfish 2660 WAC 2010 and the Sailfish 2860 CC 2009 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 - Sailfish 2660 WAC 2010 at 26,2 ft versus Sailfish 2860 CC 2009 at 28,0 ft. Weight tells a clearer story for trailering families: the Sailfish 2860 CC 2009 tips the scales at 5 050 lbs - 300 lbs less than the Sailfish 2660 WAC 2010 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 500 hp, the Sailfish 2660 WAC 2010 has a 250-hp advantage over the Sailfish 2860 CC 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 2860 CC 2009 carries 240 gallons versus 200 gallons in the Sailfish 2660 WAC 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 Sailfish 2860 CC 2009 is rated for 8 passengers, while the Sailfish 2660 WAC 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sailfish 2860 CC 2009 could be the deciding factor.
