When two boats share the same hull type — in this case both the Sailfish 1900 BB 2009 and the Sailfish 2660 WAC 2008 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 2660 WAC 2008 measures 26,0 feet overall (2008), giving it roughly 7,0 additional feet of deck space compared to the Sailfish 1900 BB 2009 at 19,0 feet (2009). Weight tells a clearer story for trailering families: the Sailfish 2660 WAC 2008 tips the scales at 475 lbs — 280 lbs less than the Sailfish 1900 BB 2009 at 195 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 250 hp, the Sailfish 2660 WAC 2008 has a 100-hp advantage over the Sailfish 1900 BB 2009's 150-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 1900 BB 2009 carries 52 gallons versus 2 gallons in the Sailfish 2660 WAC 2008. 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 2660 WAC 2008 is rated for 7 passengers, while the Sailfish 1900 BB 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sailfish 2660 WAC 2008 could be the deciding factor.
