When two boats share the same hull type — in this case both the Sailfish 2660 CC 2009 and the Sailfish 3160 CC Pilot House 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?

Size is the most obvious dividing line here. The Sailfish 3160 CC Pilot House 2010 measures 31,5 feet overall (2010), giving it roughly 5,5 additional feet of deck space compared to the Sailfish 2660 CC 2009 at 26,0 feet (2009). Weight tells a clearer story for trailering families: the Sailfish 2660 CC 2009 tips the scales at 405 lbs — 333 lbs more than the Sailfish 3160 CC Pilot House 2010 at 72 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 3160 CC Pilot House 2010 has a 450-hp advantage over the Sailfish 2660 CC 2009's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 2 gal and 3 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sailfish 3160 CC Pilot House 2010 is rated for 9 passengers, while the Sailfish 2660 CC 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 3160 CC Pilot House 2010 could be the deciding factor.
