When two boats share the same hull type — in this case both the Sailfish 2660 WAC 2011 and the Sailfish 2860 CC 2010 are modified vee designs with fiberglass construction — 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 2011 at 26,2 ft versus Sailfish 2860 CC 2010 at 28,5 ft. Weight tells a clearer story for trailering families: the Sailfish 2660 WAC 2011 tips the scales at 7 325 lbs — 6 820 lbs more than the Sailfish 2860 CC 2010 at 505 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.

Both boats share a closely matched power ceiling — 500 hp for the Sailfish 2660 WAC 2011 and 500 hp for the Sailfish 2860 CC 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sailfish 2860 CC 2010 carries 24 gallons versus 2 gallons in the Sailfish 2660 WAC 2011. 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 2010 is rated for 8 passengers, while the Sailfish 2660 WAC 2011 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 2010 could be the deciding factor.
