The Sailfish 2100 BB 2007 vs Sailfish 2660 WAC 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Sailfish 2660 WAC 2007 measures 26,0 feet overall (2007), giving it roughly 5,0 additional feet of deck space compared to the Sailfish 2100 BB 2007 at 21,0 feet (2007). Weight tells a clearer story for trailering families: the Sailfish 2660 WAC 2007 tips the scales at 475 lbs — 454 lbs less than the Sailfish 2100 BB 2007 at 21 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 2007 has a 275-hp advantage over the Sailfish 2100 BB 2007's 225-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 2100 BB 2007 carries 63 gallons versus 2 gallons in the Sailfish 2660 WAC 2007. 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 2007 is rated for 7 passengers, while the Sailfish 2100 BB 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sailfish 2660 WAC 2007 could be the deciding factor.
